Cannot access router

zer0 · Post by **zer0** » Thu Apr 30, 2015 3:11 pm

I recently setup Gargoyle on an old WRT54G v2 (I cannot recall the version, but I think it was 1.6) as a Wireless bridge, to connect my NAS and old iMac. Everything was pretty easy to setup. However, it started to freeze up and cause connectivity issues whenever I'd try to access my NAS.

Earlier today, I logged into the router, and got some incredibly slow load times. Eventually, FF kept telling me that the server was refusing connections. At one point I was able to get back in, but I again got nowhere, fast. So I tried the 30/30/30 reset. It seemed to work, but now I cannot get into my router.

The NAS and computer are connected directly to it, but when I try to determine the IP to access the router, I get nothing. My iMac is being assigned an IP that is not within our local range, 169.x.x.x instead of 192.x.x.x, and no longer shows any router information. So far, nothing changes this (reboots, resets, DHCP release, nada)

I need help figuring out to get back into my router! I've seen a lot of posts to manually set an IP within the range, but I don't know what range it's using now. I've seen plenty of suggestions to telnet in, but this is over my head, and again, I'm not certain that would work if I'm unable to get anything to acknowledge the router.

How can I get my router back?

Thank you, I will try this over the weekend. I'm not sure I'll have the time, tomorrow.

Sadly, the first 2 options have not yielded results.

I set my IP to the suggested number, can get into the failsafe recovery, but I am unable to ping or telnet to the router.

I tried a couple of times, using the Wireshark method, but it doesn't show the default 192.168.1.1 anywhere. I see the IP assigned, and all the 169.x.x.x IPs that also connected to it. Is there another method, excluding the JTAG?

This comment actually leads me to think that Gargoyle is up and running!

Could you:

disconnect everything from the router and reboot it
use a cable to connect your PC to a LAN port on the router
on your PC set your wired Static IP address to 192.168.1.2 with netmask = 255.255.255.0 and gateway = 192.168.1.1.
Open a browser and enter 192.168.1.1 in the address bar (not the search)

If nothing then:

This last para leaves me a little unsure of exactly where you got to - and what the next step might be. Can you tell me which dot point on the Using Failsafe recover mode you get stuck on:

Disconnect all cables from the router!

Admittedly, I had not fully setup the manual address. This was an oversight on my part. I just went back and set my address to 192.168.1.2, with the default gateway, and 192.168.1.1 as the router. I unplugged everything, and plugged the iMac back into the router after power cycling it.

Sadly, nothing has really changed.

Wireshark does not show any information from 192.168.1.1. Though, it has shown some information that looked like it'd be from the previous setup. ("Who has 192.168.0.1? Tell 192.168.0.2.) Struck me as odd, as this should not be a bridge anymore, since I've 30/30/30'ed it so many times.

I agree, it appears to be working. Before unplugging everything, the iMac could see it's neighbor, the NAS, but that was it.

The last bullet point I had success with would be getting the router to enter failsafe mode. Everything involving connecting to it, does not work. I seriously think this is bricked, now. Crap.

looking on the bright side - now you get to go out and buy a brand new router

(I am still not really convinced that it is dead, I think something else is going on. But I cannot guide you further sorry)

You've mentioned 30/30/30 reset.
This does nothing. It doesn't apply to Openwrt.

http://wiki.openwrt.org/doc/howto/generic.failsafe
Try this set of instructions.
I kind of prefer it to the ones in our documentation. Also on a Mac you shouldn't need wire shark you can just use a Linux terminal.

what I do sometimes

Direct connect with Ethernet cable

Code: Select all

PC -- Gargoyle(LAN Port)

Fix IP address on PC

Reboot PC (optional - Just making sure)

open command prompt

and run

Code: Select all

ping 192.168.1.1 -t

Then reboot your router

at some point you should get a ping back

I feel like a bit of tool, now. I wish I could remember how I got taken, during my Googling, from Gargoyle into DD-WRT. I will review the OpenWRT documentation, and try again. Thank you for the link.

Sadly, I don't know as many of the Terminal commands for OS X as I should. (Luckily, I know I don't need the -t for my ping.) I don't think Wireshark is proving itself too helpful in this case, anyway.
