Windows 10: Router Firmware Re-flashing Problem

I installed the OpenWRT firmware on my netgear wndr4700 router to see what I could get out of it; I decided to go back to the default netgear firmware, so I tried to follow the instructions here, but its been giving me problems

first off, I open the ipv4 settings on my ethernet properties, and I change the ip address to 192.168.1.10, the subnet mask to 255.255.255.0, and the default gateway to 192.168.1.1, then after saving the settings I run the tftpd64 client, select my ethernet as the server interface, and the other fields as it should. I got the netgear firmware file on me, I run the client, I power off my router, wait 10 seconds, power on, and wait for the power icon to start blinking

problem is, when the power icon on the router starts blinking, the server interfaces changes from the ethernet to something called software loopback interface 1 (ip address 127.0.0.1), and I quickly change it back before the router fully boots, click put, and it keeps giving me an error (something something 10025 error something) saying it fails; when I re-check the ipv4 settings on my ehternet, the default gateway field keeps going blank when my router boots

to those who can help me with this, please tell me what im doing wrong and how to fix it (hopefully without bricking the netgear router

:)

 

DNS problems with router

A couple suggestions I have for you:

Update the firmware on the router. Maybe it's getting into a badstate, and a firmware update might fix it. Or if you're comfortable with it, install a custom firmware like dd-wrt. Just make sure its supported on your router first.

Change your DNS to: 8.8.8.8, 4.2.2.1. Might help.

If none of these work, maybe statically set your DNS on your PS3/PC to the IPs you listed, taking the router out of the lookup procedure.

Last option, is look for a new router.

 

How to factory reset Cisco 1700 Router

Hopefully I can help you here....its a very common thing to happen.


First, I take it you dont know the passwords for console access or telnet/ssh?

I will assume that these devices belong to you.

step 1. Plug a cisco console cable into a serial port on your pc
step 2. Plug other end into Cisco console port
step 3. Using hyperterm or putty or similar connect to the serial port
step 4. boot router, and make sure you clearly can see the output (this confirms you have good serial comms)
step 5. if this fails, adjust the comm port settings (9600, 8,1,n are the default)
step 6. now you have to do the only hard part...send the break command:

Break command list: Break Commands

Go down the list and match your OS and SW and try the sequence suggested.

If this fails several times do what I do: Install putty (free) and then to send a break so you can get into rommom just hit "ctrl-a b".

 

Flashing to DD-WRT help

I have a WRT-54G V5.0 and it and DDWRT go hand in hand! i love it personally cause it lets the router do TONS of things that the other firmware had blocked. It was relatively easy, just follow the step by step instructions on the DDWRT website and for most WRT54G routers, you have to use the micro firmware cause of limit mem size on the router
