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
Notes for various routers
This router has TFTP enabled out of the box. You _must_ set your computer's IP address on ethernet, however, to '192.168.1.15' in order to be able to use a command-line TFTP client.
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:
Operating Systems: TFTP clients
Windows 7/Server 2008
TFTP is disabled by default. In Control Panel > Programs and Features, click on Turn Windows features on or off, find TFTP Client and tick the box. You should now be able to use TFTP from the command prompt
using whatever your Linux distribution's package management might be, you need to check for the presence of a tftp client, and if necessary, install that package. Instructions for xUbuntu/Linux Mint (xUbuntu means any Ubuntu based distribution, including Kubuntu, Xubuntu, etc. Instructions for Debian may be similar, but are not yet tested).
(Linux: for Ubuntu/Linux Mint only)
tftp client may not be installed by default on Ubuntu 12.10 or Linux Mint 14. check and see if you have it by issuing:
dpkg --get-selections | grep tftp
if you do not have the client, then install it with:
sudo apt-get install tftp
Enabling TFTP on various routers
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.
nvram set boot_wait=on nvram set boot_time=10 nvram set wait_time=10 nvram commit && reboot
OpenWRT has wifi disabled per default.
Remove the line indicated:
config wifi-device radio0 option type mac80211 option channel 11 option macaddr 00:1c:10:bc:a7:1f option hwmode 11g # REMOVE THIS LINE TO ENABLE WIFI: option disabled 1
Wait a few minutes, then ssh back into the router.
Run 'wifi'. You should see the following:
root@OpenWrt:~# wifi Configuration file: /var/run/hostapd-phy0.conf Using interface wlan0 with hwaddr 00:1c:10:bc:a7:1f and ssid "OpenWrt"
Connecting to wifi
You will need internet access to install packages and other things. Edit your config wifi-iface section to match the example below.
config wifi-iface option device radio0 option network wwan option mode sta option ssid sudoroom option encryption none
If you're on an encrypted network add the following options...
option encryption psk2 option key 1234567890
Next add the "wwan" interface.
config interface wwan option proto dhcp
Restart networking and you should be set. /etc/init.d/network restart
