Hello, dear readers of the inforkomp blog. So, as you understand from the title of the article, today I want to return to the topic again: setting up a wireless access point. To be more precise, I want to talk about: how to flash a router and why do it. I will show the process of resetting the software using an example. Wi-FI router Dlink Dir-300. But, if your router model is different from the one shown here, it’s okay, the process itself is the same, except that only the design of the settings window and the name of the menu items will differ.

Why did I decide to write specifically about the router firmware? First of all, the idea of ​​writing an article about router firmware update, but I couldn’t get it together and do it. The second reason is that recently, many of my friends have begun to ask me exactly this question: how to flash a router, what to press and what firmware to use.

As a rule, many users initially try to update it. For example, when purchasing or setting up a new device, I personally check the firmware version and, if possible, update it to the latest version. And you know what, my router has probably been working for more than a year now and has never frozen.

I believe that it is necessary to update the firmware on the router. The very meaning of updates is that when developers release new firmware versions, they correct all the shortcomings and errors that could appear when working with the Internet and the router. Moreover, the process of flashing the router itself is very easy.

Therefore, if you have serious problems with Wi-Fi, then be sure to read the article and try to reflash your Wi-Fi router.

Why reflash your router?

Well, there can be a lot of reasons to flash a router. Here are a few of them:

• 1. The most common reason is updating the firmware for stable and high-quality operation of the Wi-Fi signal;
• 2. No device receives a Wi-Fi signal;
• 3. The message that the smartphone and computer is constantly on;
• 4. The Internet cable inserted into the WAN port is not visible or not detected;
• 5. The Wi-Fi signal constantly disappears and appears; etc.

In general, there are simply a huge number of types of problems that the router firmware can help you deal with.

Preparation and selection of firmware

IMPORTANT!!!

• Choose your firmware carefully. Do not make a mistake in determining the hardware version of the device;
• Disconnect the Internet cable from the router, leaving only the power supply and connection to the computer;
• You should only flash the router using a network cable, which we connect to any port of the access point (except WAN), and the other side to the computer’s network card. You cannot update the router software using WiFi;
• All settings, passwords and logins will be reset to factory settings. What, after the update you will have to configure it again;
• Do not turn off the access point while flashing;

Well, let's start by determining the revision of the router and downloading the required firmware. In order to find out the hardware version, we need to turn the device over and look at the sticker with technical information. I have this " H/W Ver.: B5" And " F/W Ver.: 1.2.94“Therefore, for those who have the same revision or B6, then download the firmware here: link.

For those who have Dlink dir-300 NRU B7, download the update from this link, selecting the desired version. For owners of routers with revision B1, B2, B3, download. If you have a different router, then go here, and in the list that appears, select the device with the appropriate revision. Then, going to the folder " Firmware", which contains the latest firmware version in the form of a "bin" file.

Now, by clicking on the file, we save it to the computer.

Once again, be careful when choosing the firmware version. Because if you try to install the firmware that is required for revisions B1-3 on a router with revisions B5-7, this may cause it to break. And it will be possible to restore its functionality only at a service center by paying a certain amount for it.

Firmware for D-Link Dir 300 router

As always, for any setup, first use the technical data (password, login) indicated on the sticker. If you accidentally forgot your password, then you will need.

The web interface window of our device will open.

To start updating the router firmware, you need to go to the following menu items: “ System» -> « Software Update».

In the firmware update menu, click on the " Choose"We will be required to find the downloaded file and open it. If the name appears next to the selection button, then everything is in order. To start the process, click on “ Update».

All that remains is to wait for the firmware update to finish and reboot the router.

The next time you enter the settings, use the standard password and check the current software version.

Also, do not forget that all settings are abandoned. Therefore, be sure not to forget. Leave comments if you have questions or need help finding the right firmware.

Updating the firmware of the D-Link Dir 300 router

Hello, I have already written a lot in various articles about setting up Dlink routers. And I received many comments with the question of changing the firmware or restoring the firmware. I decided to write one complete article about router firmware from Dlink Dir 300 companies. Here I will try to answer all questions, explain the change to a newer firmware on all previous versions of the software. And of course, we’ll consider restoring the firmware of this model.

How to determine what router model you have

In order to start downloading the firmware. You must first decide on the version of your router, since the Dlink company has released a huge number of series for the Dir-300 model. To find out exactly what model of router you have, you need to look at the back panel of the router, where your version of the router is written on a special label. They look something like this.

As is clear from the images, “H/W Ver:” indicates the router model, for example B5 C1 A1, and F/W Ver.: the firmware version.

Where to download software (firmware)

After we have decided on our router model, we need to download new firmware. We can do this on the official website of the Dlink companies, here is a direct link to all versions https://ftp.dlink.ru/pub/Router/. Here you can find firmware for all routers and company devices. We find our devices in the lists

Let's go to the folder of our model, I will go to the DIR-300_NRU folder since there are firmwares for several router models at once.

Going to the model folder, select the folder with the firmware for it “Firmware”. After that, inside this folder we will select our router model, I will select the B7 folder.

After entering this folder, the very first file will be the latest version of the software for our model, and in the “Old” folder there will be all previous versions.

Firmware DIR-300 is the latest developed interface.

Let's start with the most important thing: the latest version of the Dlink development interface. This version includes firmware (1.4.0, 1.4.9, 1.5.0, 2.5.0 and many others starting with versions 1.4.0). This firmware is supported by models C1, B2, B2, B3, B5, B6, B7 (maybe there are other models, write in the comments and I’ll add them). Externally, this interface is designed in dark colors, dark gray. Detailed description about that.

After we have entered the interface, go to “Advanced settings”. Then in the “System” column, click on the forward arrow once.

And select “Update software” from the menu item.

In the soldered window, click the “browse” button and find and select our .bin file. Then you will need to click the “Update” button and wait until the firmware is installed.

Attention: Do not turn off the power of the router until it is completely updated, otherwise the update will fail.

Firmware 1.3.0 previous interface

This type of firmware has a white-blue interface and is suitable for models DIR-300 NRU B1, B2, B3, B5, B6, B7. To update the firmware, you need to go to the router settings; if you don’t know how to do this, then you first need to find out. By default, it is usually 192.168.0.1 Login and password are also by default admin/admin or the data that you specified in the settings.
Then select in the window that opens. Select “System” from the top menu, then select “Software Update” from the menu below. Now, by clicking on the “Select file” button, find your .bin file, and click update settings.

.

Firmware 1.2.x second version of the interface

The interface of this firmware is a combination of white and dark green (probably something like this, if not, correct it in the comments). Just like 1.3.0 is suitable for many routers. To configure, let's go to the router interface (if you don’t know how, read). Then select “System” in the menu on the right, and in the drop-down menu, select your new firmware. Then click the "Update" button.

.

Firmware 1.x.x first version series A1 C1 B1

The very first version of the firmware, if you have it, it means you bought the router a long time ago. The appearance of the interface is a combination of dark gray and yellow. Suitable for initial series like A1 C1 B1 and B2. We go to the router interface, . Then select “MAINTENANCE” in the top menu, then select “Firmware” in the left menu. In the “Firmware upgrade” section, click on the “Browse” button and select our new software version. Then click on the “Upload” button.

.

Solving the problem with changing the DIR-300 C1 firmware

The D-Link DIR-300 C1 router with firmware 1.0.0 has a problematic firmware method. To flash the firmware for this router, you need to install a third-party program from Dlink companies. You can download this program from the link ftp://ftp.dlink.ru/pub/Router/DIR-300A_C1/Firmware/bootloader_update/dcc_v.0.2.92_2012.12.07.zip. Then unpack the archive and run the dcc.exe file, a window will open

After which you need to click on the “Connect and configure device” button. Then keep clicking “Next” (you can read the information in the windows). Then the flashing process will begin, it will take some time.

Emergency firmware recovery

It very rarely happens that the router will be reflashed unsuccessfully, and you will not be able to access the router settings at 192.168.0.1. Then you will need to restore the firmware, fortunately the Dlink company has simplified this action for us.

And so, in order for us to restore the firmware, we must first leave one connection with the computer’s router. The next thing you need to do is configure the network card with a static IP address. And in the “IP address we” field we put 192.168.0.10 and in the “Subnet mask” field we put 255.255.255.0.

Without releasing the button, we restore the power to the router, wait until the router boots up for about 15 seconds, then release the Reset button.

Now open any browser on your computer and enter 192.168.0.1 in the address bar. The firmware recovery page will open in front of us.

Here, by clicking on the “Browse” button, we need to find our .bin file, with the firmware from the router. And click on the send button. We all wait 4-5 minutes.

Now let's restore the network card settings to automatic

That's it, the firmware recovery is complete and you can proceed to.

Let's talk about updating your firmware on d-link routers. Using me as an example I will update the firmware on the d-link router dir-300 but the instructions will help you with other series of d-link routers
So, first you need to know the version of your router And firmware version what is installed on it
You can see this on the router itself (usually on the back)

It's hard to see in the screenshot, but it says:

This means that the generation version b7. That is, dir 300 of the n7 generation with firmware version 1.3.0. If you do not have access to the router, but you know its Ip: (often 192.168.0.1 or 192.168.1.1), then to view the router’s firmware version, enter 192.168.0.1 or 192.168.1.1 into the address bar of any browser. If you haven’t changed your login and password, it’s often admin, admin (login and password admin)


Let's go and look at the version router, version firmware and etc.


Now we go here and further along the path indicated below we find the new firmware

CAREFULLY! You may have a different firmware, so it’s better to watch the video at the beginning of the article! Super, let’s move on. In my case, to update the D-Link 300 nru7 rev b7 firmware, I downloaded the latest firmware, called 20130220_1810_DIR_300NRUB7_1.4.8_sdk-master.bin; in your case (depending on the router model), the firmware may be different, so please consider reflashing the router very responsible, so as not to kill the device called a router!
The firmware has been downloaded. Go ahead. Now you connect the router and computer via a network cord. An empty slot (one of 4) will have an input, and the output will be your computer or laptop.
The diagram roughly looks like this


After this, open 192.168.0.1 or 192.168.1.1 again and enter your username and password. Usually this is admin, admin if you haven't changed anything.
Now go to (in your case there may be a different path, but the essence is the same!) System - Software Update and indicate our firmware, then click Update.


In a couple of minutes, the firmware on the router will be updated. It is advisable to know the connection parameters and your MAC address before updating, as stated in the video at the beginning

Despite the fact that the DIR-300 firmware does not have such a large number of differences from previous versions of this device, users often ask questions about where to download such firmware, as well as how to properly use the updated web interface. However, in fact, it is enough to understand the extremely simple instructions, and then you can do all the procedures completely independently.

How to download?

It is immediately worth noting the fact that this instruction is relevant only for those routers that have the inscription H/W: D1 on the sticker below. In other cases, other DIR-300 firmware is needed.

Before you start installing the software, you should download the firmware file from the official website. On the site itself, you will need to go to the pub-Router-DIR-300-Firmware folder. You should pay attention to the fact that in this folder there are several directories under the same name, which differ from each other by underscores. If you bought your router in 2015 or made an even later purchase, then you will need to select DIR-300 firmware with the ending “A_D1”.

This folder contains the latest firmware versions intended for the corresponding router. As of January 2015, the latest version is 2.5.11.

Preparation

If you have not yet connected your own router, and have not previously dealt with similar procedures, you should perform a certain set of works before getting the DIR-300:

• Connect the router cable to the computer. In the vast majority of cases, this cable is included in the initial configuration of the device. One end of the wire is connected to the computer's network card, while the other is connected to the LAN 1 connector on the router itself. If your computer does not have a network port, you should connect this device via Wi-Fi.
• Connect power to the router. If you are going to flash the DIR-300 router via a wireless connection, then after a certain time the DIR-300 network will appear, in which password protection will not be installed, and you will need to connect to it.
• Launch any browser convenient for you, then type 192.186.0.1 in the address bar. If this page does not open, you should check that in the characteristics of the connection you are using in the “TCP/IP Protocol Properties” section there is a checkmark next to the “Obtain IP and DNS automatically” section.
• When you are asked for your username and password, you will need to enter admin. It is worth noting the fact that when you first log in, most likely, you will be asked to change the standard password, and if you still decide to change it, do not forget it, since then the setting will be blocked for you in the DIR-300 router. If the password doesn't work, then you or someone else has already changed it before. In this case, it is recommended to completely reset the starting characteristics of the router using the Reset button located on the back of the device. After this, the configuration must be carried out again in the DIR-300 router.

If all the above procedures were successful, then you can immediately proceed to the next part.

Firmware

Depending on what firmware version is currently present on your device, after logging in you will see one of the interface options. Pay attention to this point.

Gray interface

The gray background of the interface is typical for firmware versions 1.0.11 or 1.0.4, and in this case you should perform the following procedures:

• Go to the “Advanced Settings” category using the button at the bottom of the screen. If necessary, you should switch the language using the Language button located at the top of the page.
• In the “System” column, click the double right arrow, and then select “Software Update”.
• Select the firmware file you need, which was downloaded earlier from the official website.
• Click "Update".

Then you will need to wait a certain time before the firmware is installed on your Wi-Fi DIR-300. If it seems to you that everything is completely frozen or the page is in the “Not responding” state, do not be surprised, this point will be discussed in more detail later.

White interface

The white interface is typical for firmware version 2.5.4 or 2.5.11, as well as for subsequent versions. In this case, you will need to do the following work to update:

• On the left side of the menu, select “System”, and then click on “Software Update”. Do not forget that if necessary or to ensure greater convenience in working with the interface, you can switch its language using the corresponding button at the top of the screen.
• Go to the “Local Update” section, click on the “Browse” button and look for the firmware file that you previously downloaded.
• Click the "Update" button.

Within a short period of time, your DIR-300 will be updated, the Wi-Fi connection will be completed, and you will be able to use the Internet.

What to do if everything is frozen?

If, during the process of installing the update, it seemed to you that the device was completely frozen because the progress bar was constantly moving in the browser or it simply displayed that the page was inaccessible, this situation occurs because during the software update process the connection between the computer and the router is completely lost . Thus, you will have to wait for one or two minutes, then connect to this device again and enter the settings to see that the firmware has been updated normally.

If you have experience from this manufacturer, you can begin to determine the device parameters on your computer, since the same principles are used in the DIR-300. Instructions for those who do not have experience in such selection of configurations are below.

How is the setup done?

Despite the perceptions of many users, there is actually nothing difficult about setting up a router correctly. To do this, you will need literally 10 minutes of free time and a competent approach to business.

How to connect?

Initially, you need to connect the device to the network itself. To do this, you will need to plug your Internet provider cable, which was provided to you during the installation process, into the yellow Internet port on the back of the router, and connect one of the LAN connectors to the network card of your computer. It is worth noting the fact that the most convenient is the wired setup of the DIR-300. The WRT firmware and other variations, of course, allow you to carry out the firmware even wirelessly via a tablet or phone, but still it is the wired mode that can be called the most convenient among all existing ones. Now connect the router to the outlet, but do not rush to try connecting to the Internet through it from various wireless devices.

If you have some kind of TV set-top box, then in this case you can also connect it to one of the LAN ports, but experts recommend doing this after the final setup of the equipment, since in some situations the set-top box greatly interferes with normal setup.

How to go to settings?

It’s worth noting right away that a fairly common mistake made by modern users is that the network is actively connected during the setup process on the computer, both during setup and after it. You must first completely disconnect the current connection if it is running on your laptop or personal computer, and subsequently do not connect it until the setup is completely completed. The router will independently establish a connection and also “distribute” the Internet to all kinds of gadgets.

Now launch a browser and enter 192.168.0.1 in the address bar. You will see a window in which you will be asked for a password and login, and you should enter the word “admin” in both fields. This password and login are set by default in the standard web interface of this router.

What to do if it doesn't work?

If, after entering this data, the system sends you back to the input page, this means that someone tried to change the router settings, and, in particular, changed the standard password, since you are asked to change it at the first login. It happens that you cannot remember it, in which case you will need to reset the device to standard settings. To do this, you need to press the Reset button located on the back of the case, and not just press, but hold for 15-20 seconds while the router is connected to the network.

How to setup?

After entering your login and password, you will see the main page of your router’s interface, where all the settings are present, and where we previously updated the DIR-300. At the bottom of the page you will need to click “Advanced settings”, and if necessary, change the initial interface language.

After that, go to the “Network” item and select the WAN section. Now you should see a list of connections, where you will see the only active one, which you need to open. Its parameters should be as follows:

• connection type - “Dynamic IP + L2TP”;
• name - may remain standard, but often users prefer to enter something more convenient (this does not in any way affect the functionality of the installed equipment);
• username - here you will need to enter your individual Internet login (for example, for the Beeline network it usually starts with 0891);
• password and confirmation - again, the Internet password is entered in order to gain access to the network;
• VPN server address - check with your provider's service center.

Experts recommend leaving all other parameters at default and not trying to change them if you are not a qualified specialist. Now you can click the “Change” button, after which you will again be thrown to a page with a complete list of available connections. After this, you should turn your attention to the indicator located in the upper right part of the screen - you need to click on it and select “Save”, which will allow you to completely save the settings in the router’s memory so that they will not be reset later in the event of a power outage.

If you enter all the relevant information correctly, and there are no active L2TP connections on the computer itself, the next time you refresh the browser page you will find that you have a configured Internet connection and have access to the Internet. Now all that remains is to configure the basic security settings, or more precisely, set some complex password for the DIR-300 router.

It is recommended to set some really complex combination as a password so that no one can connect to your Internet from the outside. You can use random password generators or simply create your own combination of numbers and letters.

Situation in which it is necessary to do restoring firmware on DIR-300 routers different revisions may arise for various reasons. In addition to a malfunction in the firmware, when a WiFi router simply stops distributing the Internet and its web interface becomes unavailable, this could also be a simple rollback to the usual “stock” firmware after DD-WRT. Or it could be a recovery after an unsuccessful flashing, when the router was fed firmware from a different hardware version.
In general, the developers - the D-Link company - foresaw such a development of events and on many modern devices they created an Emergency Web Server or Failsafe UI, which is actually the same thing. Now let's figure out together how to use it.

Before doing anything with the router, you must first download the firmware from the official D-Link server - ftp.dlink.ru:

You can find out what hardware version of DIR-300 you have on the sticker on the back cover of the case:

After that, go to the desired folder on the server, look for the “Firmware” directory there and download the latest firmware version and the previous one, just in case. After that, we begin to conjure with a piece of iron. We disconnect the provider’s cable from it and all clients, except the computer from which we will do the recovery.
Then we do this - go to the Local Area Connections settings and manually enter the IP address in the properties of the TCP/IPv4 protocol 192.168.0.2 , mask 255.255.255.0 and the gateway - 192.168.0.1 :

You can register the addresses of DNS servers, or you can not - this is not important, because they will not be used. Click on OK and close the settings.

We take our DIR-300 in our hands and press the button Reset:

Keeping it pressed, turn off the power to the router with your other hand and turn it on again. Wait 15 seconds and release Reset.

Now you need to launch an Internet browser and enter the address in the address bar - http://192.168.0.1. The result should be like this:

There may be another nuance here. Earlier DIR-300 models had a disaster recovery interface at a different address. Therefore, if your router does not respond to 192.168.0.1, then again go to the properties of the TCP/IP protocol and register the following IP:

IP: 192.168.20.80
mask:255.255.255.0

You also need to enter the address 192.168.20.81 in the address bar of the browser:

The interface of Emergency Web Server and Failsafe UI is virtually identical - a file selection button, and a button to start flashing. Click on “Browse” and select the downloaded file with the firmware. Then click on “Upload” and wait for the process to complete.

What do we have as a result? Working router D-Link DIR-300! All the best!
