Yesterday evening, taking a break from all the tips, I tried to change my router back to the factory firmware (when I changed it to beeline myself), I ran into difficulties. First of all, I tried to update stupidly through the menu, indicating the factory firmware version 1.3.3, the update did not happen, that is, the tsatus went that the update then even wrote that it was successful, but the standard Beeline menu comes out (the address of the router on the Beeline firmware is 192.168.1.1). then following the advice (of course the router is connected to the computer) I set up the network connection ip 192.168.0.10 mask 255.255.255.0 on the computer, cut off the power of the router I clamp the rezet I turn on wait 15 seconds (I tried both 20 and 25) trying to constantly go to the router at the address in the line 192.168 .0.1 (and 192.168.1.1 too) tried both opera and google chrome and IE in general did everything as they said in the article here I will immediately say the router did not go into the mode of replacing the firmware so to speak "emergence room" here is a copy of the article but it is for more early assemblies, there is not much difference in principle

So let's go:
1. If the router does not show any signs of life, or only the orange "power" diode is on, then first of all we take out all the cords from the router, including the power supply.
2. Download from

the firmware, the .bin file from the DIR-300NRU / FIRMWARE / B1_B2_B3 folder strictly for our router and save, for example, directly to the C drive
3. We go to the settings of the network card and in the properties of the TCP / IPv4 protocol, write the IP address 192.168.0.10 mask 255.255.255.0
4. Next, we connect the network card of our computer with a wire to one of the LAN ports of the router, let it be LAN1.
(To return the factory DIR-100 firmware, you need to connect the computer's network card to the WAN port of the router (internet). Specify the location of the previously downloaded firmware and follow the fla link.)
for dir-100
5. In the off state, hold down the RESET button (with a match or other blunt object) and while holding it, connect the power to the router
6. Without releasing, hold down the RESET button (20 seconds), wait until the emergency recovery mode of the router is loaded.
7. In the Mozilla or Opera browser (not IE only), type the address 192.168.0.1 and lower the RESET button.
8. Indicate where the firmware is located (where we downloaded it) and click Upload firmware now.
Next, we wait until the update is completed.
9. If everything is done correctly, then after completion we will see the authorization window of our D-Link /
Login and password will be returned by default admin / empty
After such simple manipulations, you can restore the D-Link factory firmware after a failure, unsuccessful firmware, or after third-party firmware.

I will repeat this article HAS NOT HELPED
in the end, all ingenious is simple

It is necessary from the dlink repository office http://ftp.dlink.ru/pub/Router/DIR-300_NRU/Firmware/ to choose our assembly in our case "B5" (you can find out on the sticker on the bottom of the roter) ONLY ITS if you flash B3 then hike in the service is guaranteed in the same place on the storage you can find other useful information such as instructions for different versions of the software http://ftp.dlink.ru/pub/Router/DIR-300_NRU/.
LOOKING FOR software with the extension .fwz I chose (DIR_300NRUB5-1.2.94-20110414.fwz)
then entering the standard Beeline menu of the router at 192.168.1.1, entering the advanced settings, then the system, updating the software, select this downloaded file, click to update updates for a longer time, but no more than 4 minutes and as a result, the connection is broken or more at 192.168.1.1 the router does not appears, go to the address 192.168.0.1 and get into the router menu that was from the store, the default login and password (login admin, password admin) then update where we want and how we want, I had a need to leave the biline firmware in connection with the change of provider on TTK (left the goodline on it with the Beeline firmware it worked well) I previously connected the Beeline and the factory router from the store went to the Beeline, since the IP TV set-top boxes to the TV behaved inadequately after the rewiring, everything became stable.
