WRT54G Wireless-Ethernet Bridge
These instructions show how to setup a Linksys WRT54G as a wireless-ethernet bridge.
- For pictures see http://www.ppckernel.org/~tobias/photos/index.php?folder=/wireless/.
- To monitor the networks this setup can see, visit http://dev.tobias.public.cs.earlham.edu/~tobias/wireless-link
Disclaimer: The firmware linked to below has only been minimally tested and it might brick (i.e., permanently and irrevocably break) your router.
- 1. Download a copy of the firmware binary from http://www.ppckernel.org/~tobias/hwrt/
- 2. Enter the router admin interface and update its firmware with the file you just downloaded
- 3. Turn off the router's DHCP server
- 4. Open the Administration tab and then the Startup script (near the bottom). Type the following into the dialog that appears:
# choose the antenna port you want to use # uncomment if you're connecting a third-party antenna # wl antdiv 0 # wl txant 0 # set the transmit power to 22 db (the max in the US is 36 db, and my antenna is 14; 36-14=22) # wl txpwr1 -o -d 22 # turn off access point mode wl ap 0 # turn on wireless-ethernet bridging wl wet 1 # join a wireless network wl join <SSID>
If you want to learn more about these commands simply open a telnet session to the WRT54G, type
wl, and hit return
- 5. Hit Save, and then reboot the router.
- 6. You can check for available wireless networks by visiting http://192.168.1.1/Scan.htm or typing:
wl scan wl scanresults
in a telnet session.
- 7. Connect the device(s) that you want to bridge to the LAN ports on the WRT54G (i.e., not the Internet port). You can bridge up to four devices at a time; with an extra switch you might even be able to bridge more (haven't tried it).
