The situation in which you need to do firmware recovery on DIR-300 routers different revisions may arise for different reasons. In addition to the failure of the firmware, when the WiFi router simply stops distributing the Internet and its web interface becomes inaccessible, it can be a simple rollback to the usual "stock" firmware after DD-WRT. Or it may be recovering from an unsuccessful flashing when the router was fed firmware from a different hardware version.
In general, the developers - the D-Link company - provided for such a development of events and on many modern devices they made the Emergency Web Server or Failsafe UI, which is actually the same thing. Now let's figure out how to use it together.

Before doing any actions 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 required 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. Disconnect the provider's cable and all clients from it, except for the computer from which we will do the recovery.
Then we do this - go to the Local Area Connection settings and manually register the IP address in the TCP / IPv4 properties 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, since they will not be involved. Click on OK and close the settings.

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

Keeping it pressed, turn off the power of the router with the other hand and turn it on again. We wait 15 seconds and release Reset.

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

There may be one more nuance here. Earlier DIR-300 models had an emergency 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 this kind of ay-pi:

IP: 192.168.20.80
mask: 255.255.255.0

In the address bar of the browser, you also need to enter the address 192.168.20.81:

The interface of the Emergency Web Server and Failsafe UI is actually one to one - the file selection button and the flashing start button. Click on "Browse" and select the downloaded firmware file. Then click on "Upload" and wait for the end of the process.

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

The Dlink dir-300 wireless router is a kind of dinosaur among the routers of its class, suffice it to say that after the first model Dlink dir-300 became obsolete, various analogs of Dlink dir-300 B1, B2, B3, B5, B6, B7 began to appear which surpass in terms of speed and functionality of its prototype. But, in order to use additional functionality without interruption, I recommend updating your Dlink to the latest firmware, this is what this article is about.

The first step is to set up a network on a computer / laptop on automatic acquisition of IP address and DNS server

Before updating the firmware, be sure to check the hardware revision (H / W) of your router. To do this, take a look at the sticker on the bottom of the router. There is an inscription on this sticker that begins with "H / W Ver .:". The following letter and number indicate the hardware revision, also pay attention to the firmware version "F / W Ver .:"

After you have determined the revision of your DIR-300 NRU and its version, download the latest firmware, according to the revision
Important!!! DO NOT install the firmware for DIR-300 NRU hardware versions B1, B2 and B3 into a DIR-300 NRU router with hardware revisions B5, B6 and vice versa. This will lead to a complete failure of your device. After that, it will be possible to restore the router only for money by contacting a specialized service center.
If you have Dlink dir-300 NRU B1 / B2 / B3, then download this firmware from here .
If Dlink dir-300 NRU B5 / B6 / B7 then you need to download the firmware here from here .
If you have Dlink dir-300 A / B,download the firmware from here.
In this article, as an example, I will update the Dlink dir-300 NRU firmware (hardware revision B5), but the update process for all Dlink routers is similar, therefore it may be suitable for updating the Dlink dir-300 NRU B1, B2, B3, B6, B7.

So let's start, in a browser (Internet Explorer or Mozilla Firefox is recommended.), Enter your router's address in the address bar, by default it is used 192.168.0.1 (login admin, password admin)

Then, for security purposes, Dlink will offer to change the password, enter and click "Save".

This will open the router's web interface.

In order to start the update, you must go along the path "System - Software Update".

Then press "Overview" indicate the path to the downloaded update and click "Refresh".

This article will focus only on the dir300 router, revision B1. Turn the router over and look at the bottom surface, where its hardware revision will be indicated on the sticker (looking for the line H / W Ver: B1). This model differs from the older one in both appearance and firmware version (starting from 2.00), take a close look at the photo above. The main difference between revisions A1 and B1 is the chip on which the router is based, in our case the router H / W Revision B1 and is based on the Ralink RT3050 chip. By the way, the hardware version of the dir-300NRU WiFi router is exactly the same as that of the dir-600, which is a complete analogue of 300NRU and is produced for the European zone.

D-Link DIR-300NRU Rev. WiFi router firmware B1

Installation of DD-WRT firmware on D-Link DIR-300 Revision B1 is performed through the standard web interface of the router. Further point by point:

1. Download the firmware from this site or check the newer version at http://dd-wrt.com/site/support/router-database by typing DIR-300 B1 into the search. We need the file dlink-revb- factory-webflash.bin

2. We connect the dir-300 with a ‘straight’ network cable from the kit (any of the 4 LAN ports of the router) with a computer.
In the properties of the local area network connection on the computer, set the IP address 192.168.0.15 and the subnet mask 255.255.0.0

3. Launch the browser (it is best to use IE) and go to the web interface by typing http://192.168.0.1 in the address bar
Enter the login and password, for a new router the default login is admin, there is no password (empty) and the confirmation code from the figure. If you did, please enter your passwords.
Go to the Maintenance tab and then Firmware Update, click "browse" -\u003e look for the downloaded file dlink-revb-factory-webflash.bin, click "Upload"

4. For several minutes while the DIR300 is being stitched, you cannot turn off the power and interrupt the process in every possible way. For reliability and preservation of a certain amount of nerves, I advise you to do this operation by connecting the router and computer via UPS (uninterruptible power supply)

5. After the firmware is complete, the router will reboot and become available at 192.168.1.1. Let's enter it into the address bar of the browser and see the DD-WRT web interface. If the page does not load, try clearing the browser cache, close and reopen. The DD-WRT firmware login and password is root / admin.

DD-WRT version update

For a subsequent firmware update from DD-WRT, use the dir300-revb- ddwrt-webflash.bin. Download it here - or on http://dd-wrt.com/site/support/router-database having driven into the search DIR-300 B1.

1. Open the DD-WRT web interface in a browser, by default it is located at 192.168.1.1
2. Select the Administration tab -\u003e click "Firmware Upgrade"
3. Next "browse" -\u003e select the downloaded file "dir300-revb-ddwrt-webflash.bin" -\u003e "Upgrade"

After a few minutes, the router will reboot and refresh the web page. I recommend turning off the router after the firmware and turning it back on (some kind of power reset).

Return to official D-Link firmware

Returning the official firmware is also not difficult and the execution algorithm is exactly the same as in the paragraph - "Updating the DD-WRT version". Naturally, we need to have a pre-prepared firmware file, download -. You can also download from the official FTP server D-link ftp://ftp.dlink.ru/pub/Router/DIR-300_NRU/Firmware/ by selecting the latest version.

Rollback to factory firmware using Emergency Room

Sometimes there are situations when it is impossible to return to the factory firmware using the method described above. In this case, we use the Emergency Room.

1. Perform a reset to factory reset, either through the DD-WRT web interface, or by pressing the reset button.
2. Remove all ethernet cables, leaving only the LAN1 connection of the router -\u003e PC. We always use the "straight" wire (blue from the kit).
3. In the properties of the computer's network adapter, write the static address 192.168.0.15, the subnet mask 255.255.0.0
4. Remove the power supply plug from the router, press the reset button, and without releasing the button, plug the power back in, wait for the router to boot for about 15 seconds and only then release the button.
5. Now quickly open the browser, enter http://192.168.0.1 and in front of us is the Emergency room. Select the firmware file dir300b_v2.05_abnj.bin and click "Upload Now".

Well, now, briefly, what is this venture with a DIR 300NRU flashing for?

The firmware is based on Linux and is a miniature operating system, there are many advanced settings that are much more logical. Ability to cut the channel with priority by service (QoS). You can block sites by page address or simply by domain name.

The D1 is very similar to a similar process with other devices, but some people still have a lot of questions.

Basically, these questions are related to downloading the file "D-Link DIR-300 NRU firmware" from the website created by D-Link, as well as questions related to the updated interface in the firmware, which is clearly seen in the example of version 2.5.n

In this description, we will consider how to reflash the D-Link DIR-300 router, having received the latest firmware version 2.5.n for the DIR-300 D1 model from the website and how to correctly install it, provided that the firmware with additions and updates was installed in the router at the factory 1.0.4. In this guide, I will try to take into account all the nuances that arise during the installation.

D link dir 300 router firmware: stage 1

The explanation of how to flash the DIR-300 is only suitable for routers that have the following letters on the bottom of the case: H / W: D1. If the values \u200b\u200bare different, then you need to load the file with a different firmware.

Where to download the firmware d link dir 300

• We go to the manufacturer's Internet project, which is located at http://ftp.dlink.ru in order to download the file itself.
• On it we go to the pub pack, then to the daddy called Router, and then to the DIR-300 (underscore) NRU and in it we find the Firmware folder. It should be noted that the DIR-300 A D1 directories are located inside the Router directory. Their differences are that in one of them there is an underscore, and in the other there is no such symbol, written in one word. To update the firmware of the D-Link DIR-300 router, you need the file that I specified.

The firmware itself is located in this directory.

All of them have a name ending .bin

When this article was written, the newest firmware file was created in 2013. I will install this version in this one created in 2013. I will install this version in this manual.

Preparation before installation

If you know how to get to the settings section of the connected device, then in such a case this section can be skipped. The only thing I would like to note is that updating the firmware of the D-Link DIR-300 router and the main changes are best done using a connection to a modem using an Ethernet cable.

If the router is disabled and the user has not performed the previously described actions:

1. The router must be connected with a wire (supplied with the device) to a personal PC, using which the firmware will be executed. It should be noted that on a personal PC, the input for the network card is the LAN1 port on the device. If your mobile PC does not have such a port, you will have to skip this step. The connection is via Wi-Fi.
2. Plug the device into a power outlet. When using a Wi-Fi connection, after one or two minutes a network called DIR-300 will appear, which will not be password protected, provided that the name and other parameters have not been changed. You need to connect to the network that appears.
3. We open a browser and register it where you usually write the URL of the desired site: 192.168.10.1. If the page does not open, you need to open the TCP / IP protocol parameters and turn on the checkbox opposite the inscription to receive IP and DNS addresses automatically.
4. When the form opens, in which you need to register your username and password, you must enter admin. The first time you are asked to change your password. If you do not change it, you must not forget the new password, as it will be useful for subsequent entries in the device settings. If the password does not work, maybe you, or someone else changed it before you, you need to reset all device settings. To do this, press and hold for a while a button called Reset, which is located at the back of the router.
5. If the above was done correctly, then what we were striving for begins: flashing the D-Link DIR-300 router.

D link dir 300 firmware update using rev. B6

You will be shown the only one of the required options, it depends on the version installed on the router. This is the settings interface.

In case number 1, if the DIR-300 NRU rev. B6 version 1.n.n, you need to follow these steps.

• We press the item "advanced settings", if the Russian language is not displayed, it can be changed in the Language section.

In the "system" item, click on the arrow pointing to the right

• Next, update the software.
• Now we indicate the firmware file that we just recently downloaded.
• We click on the button called "update".

After completing all these actions, waiting for the end of the process comes. And now, the D-Link DIR-300 NRU firmware is over. If suddenly you see that the installation process has stopped, or the page has stopped, you need to go to the "notes" section, which is located a little below.

D link dir 300 router: beeline firmware

This paragraph is needed for users who need the DIR-300 NRU firmware improved version 2.n.n. In addition, this instruction is suitable if you need to install the firmware on a Beeline router.

1. Go to the settings section
2. A menu will open where we select "System", then the updated software. If necessary, we switch to Russian.
3. We go to the "local update" section and click on the "overview" button. Next, we indicate where the * .bin file is located in the file system of your personal PC.
4. Click to update.

WATCH THE VIDEO

Note

If it suddenly seemed to you that while the update was taking place or when the DIR-300 firmware was being installed, the router froze. It seems similar if you notice that a special installation bar is constantly moving in the display window of the browser page where the update is taking place.

It appears that the page is not loading. This can happen because the connection between the personal PC and the router has stopped during the software update. It is worth waiting for two or three minutes, and then reconnecting to the device.

When using a wired connection, recovery will occur automatically.

Then you should go to the settings again and see that the update has happened.

Further, the necessary device settings do not differ in any way from the settings of the same models, but with different interface options. The differences in the interface design are not terrible. Now you know how to get the D-Link DIR-300 firmware and reflash the device. Still have questions? We write them at the bottom of the article!

Over time, technology becomes obsolete, and some devices are replaced by others - new and more efficient. The same is true for wireless software. What to do with a normally functioning router but with outdated firmware, not throw it away? This article discusses the firmware of the D-link DIR 300 router.

Before proceeding with further actions, you need to understand that flashing the router carries a certain amount of risk. Sometimes it can lead to a complete inoperability of the device. Therefore, you need to update the router's firmware when there is a need for it. If your router is constantly buggy or slow, a firmware update can bring it back online.

Attention: updating the firmware of a router, the warranty period of which has not yet expired, will void the manufacturer's warranty.

Another important point: there should be no electricity problems during the firmware update process. For those of you who constantly lose light, we strongly recommend that you connect the router to the mains through.

Firmware - firmware stored in the CMOS of the computer. It is also used in phones, tablets, routers and other devices. In other words, this is a certain version of the operating system, and the process of updating it is called a flashing.

First you need to download the D-link DIR 300 firmware.

In the address bar of your browser, type ftp.dlink.ru and go to the site with the firmware. Go to the pub folder, then to the Router section.

Among the entire list of routers, find and open the DIR-300_NRU folder.

Go to the Firmware section.

Be careful in the next step. It is necessary to select the correct revision of the router model. To do this, turn the modem over and on the bottom panel look at the contents of the barcode sticker, the revision should be indicated here. In our case B1, you might have B2 - B7.

After opening the Firmware folder, select the partition corresponding to your router.

Download the file with the bin extension.

What to do next? Connect the router to your computer and turn on the power. Then check your LAN settings. In Windows 7 go to "Start" - "Control Panel" - "View Network Status and Tasks" - left menu "Change adapter settings".

Select the local area connection shortcut, right click on it and open Properties. In the window that opens, select protocol version 4 (TCP / IPv4) and click "Properties" again.

On the General tab, make sure the Obtain an IP address automatically and Obtain DNS server address automatically are selected.

If you forgot the password from entering the settings, in one of the previous articles it was told?

Pay attention to the top line, here is the revision version that we looked at on the sticker of the modem.

If, for any of the reasons: the sticker is peeled off or the letters are erased, you could not find out the revision of your device, now this can be done in the login and password entry window.

Enter admin in the login and password field, if other values \u200b\u200bwere set for user authentication, write your data.

In the settings interface that opens, go to the "System" - "Software update" section.

In the appropriate window, specify the path to the firmware file with the bin extension on the computer. At the beginning of the section about updating the D-Link DIR-300 C1 firmware, it was already mentioned.

Click the "Update" button to install the software - it will take up to 2 minutes.

Sometimes, during the firmware of the router, error messages may be displayed or the browser freezes. In this case, do not take any action, but wait 5 - 10 minutes, the firmware should complete correctly.

Firmware update DIR 300 N150 revision D1

There are several versions of D-Link DIR 300 routers on the market with different firmware revisions and different appearance of web interfaces.

Consider updating the software of the DIR 300 N150 router with revision D1 using the example of firmware 2.5.4 with the new web interface "Air".

After entering the settings of the router, the following page "Home / Information" will be displayed, where the device model and firmware version are indicated.

To update the firmware, left-click on its version. The "System / Firmware Update" page opens.

Click the Browse button and select the update file on your computer. Then click "Update". Wait for the router to reboot (1 - 2 minutes).

The file with the firmware update for the DIR 300 N150 router, revision D1, can be found on the official D-Link website or by entering the following URL in the browser address bar.

ftp://ftp.dlink.ru/pub/Router/DIR-300A_D1/Firmware/

The firmware file is named 20140228_1302_DIR_300AE_2.5.4_sdk-master.bin (see the picture above).

The software update must be performed when the router is wired to the computer.

If, after flashing, the router does not work correctly, restore the factory settings of the device. To do this, use the appropriate menu section or the hardware RESET button (press with the router turned on and hold for 10 seconds, then release, the router should reboot).

Important! Updating the router firmware is done at your own risk. If the warranty period has not yet expired, then an independent software update (not through a service center) will invalidate it.
