I did something stupid. After I installed sshd I found out that netmasq was not functioning correctly (web pages where not resolved anymore). So I restored the original firmware via CFE. However it still did not resolve correctly, so I was looking for command to reset the nvram. Since a WRT54G has something like a nvram, I was looking for something simular in the WGT634U so I run (stupid) setup at CFE. No the whole thing does not boot anymore. Here is a dump of CFE:

OK I solved my problem, at least partly. I had to use "boot -elf flash0.os" instead.

The box now boots again, only just before it arrives at the login screen, garbage is output on the screen. After I log-in and do a dmesg I see:

Out of Memory: Killed process 1174 (dnsmasq)
Out of Memory: Killed process 1189 (inetd)

Is it possible to reset the content of nvram? (it does not work from the webpage)

Nice talking to myself
I solved my problem. It seemed the rp-pppoe package was causing the problems. I just renamed the package, so it would not be loaded:

mount -t jffs2 /mnt/mtdblock3 /mnt/tmpmnt

Now I was able to do the firmware upgrade, which formats the mtdblock3. After firmware upgrade everything is working again.

I've seem to have my router stuck in a bootloop. It cant be the firmware cause I used it previously and it worked fine. Building firmware from buildroot or using the snapshots and netgear's original firmware produces the same output. I've tried zeroing all 59 sectors of the flash before flashing, or uploading the new firmware and filling the remainder with zeros, to no avail. Any ideas?

I've seen very similar symptoms on about 3-4 units out of about 150-200. They seem to work fine, then they start developing intermittent problems when booting. Eventually the problem becomes persistent and there's no way of fixing it, even with reflashing. I suspect that the problem causes faults when reading/writing data from/to memory, which in turn causes these crashes. I would suggest that you try these steps:

a) Open up the unit and look for overheating components. Try to cool them to see if it helps.
b) Replace the power supply. A good 12V 2A regulated switchmode is a good choice - a car battery would also do.
c) Inspect the unit for faulty / bloated / blown electrolytic capacitors.

I'm guessing its a hardware fault, anyway I brought it back to netgear and had it exchanged. Everything works fine now

Yes, there seems to be a LOT of power supply issues on the WGT634U. Many stock non-switching (heavy "wall-wart" style) seem to have bad electrolytics and produce lots of 60hz ripple.

I've also seen them running very high and overheating the internal buck regulators on the WGT634U board.

The moral of the story is; if you are having weird flakyness or stange lock-ups, first thing to do is swap out the external power supply with a known-good unit. (preferably a switch-mode) If your problem goes away, then take a hammer and destroy that POS wall-wart!

has aptos been able to resolve his problem ?
I'm encountering the same one. either i get an exception or it freezes.
tried with different power supply (my last try and only chance is my 12V 10A power supply)

it does start with original netgear firmware.
btw there's a new beta netgear firmware.
