Web interface method
- Power on router and let it boot.
- Press and hold power button for 30 seconds.
- Wait for router to reboot.
- Connect to the access point using LAN.
- Go to web interface, e.g. http://192.168.1.1/
- If this doesn't work, look up the reset method for your specific router.
- Find the firmware upgrade page.
- On your computer, download the firmware.
- Different versions are here.
- The snapshots directory has recent development versions.
- If you have a WRT54G you probably want this one assuming 12.09 (attitude adjustment) is the most recent stable version.
- Upload the firmware using the web form and wait for the router to reboot.
This requires that the router has a TFTP server enabled. Type these commands with the router powered off, then power on the router and it should work.
tftp 192.168.1.1 binary rexmt 1 timeout 60 trace tftp> put firmwarefile.bin
Logging in and setting root password
Telnet into the device:
If it asks for a password use 'passwd' (without the quotes).
Set a root password on the router:
Verify that you can log in using ssh from your computer:
If you can ssh into the router, disable telnet:
WRT54G / WRT54GL
If you're on an WRT54G or WRT54GL then you should do this to enable TFTP. If you're not on one of those routers, then don't do it!
It makes it easier to upgrade the firmware and recover from serious problems.
CAUTION: This will reboot your router.
