Applicable: Kamikaze, Backfire, Broadcom.
Tested: Linksys WRT54GL v1.1, Kamikaze 7.09, Kamikaze 8.09/8.09.1/8.09.2, Backfire 10.03. Platform brcm-2.4
DOES NOT WORK: Kamikaze 8.09/8.09.1/8.09.2. Either brcm47xx
Kamikaze and Backfire can be configured as a wireless repeater in AP+STA mode. In this setup a wireless network replaces the WAN as the Internet source and a new SSID directs connections to the Linksys.
The configuration files here connect the Linksys to an unsecured wireless access point (in my case, attached to the cable modem) and creates a new unsecured network called OpenWrt. In the real world you will be using encryption; change your encryption type to wep, psk, or psk2 and insert the correct passphrases/keys, using the commented examples.
Just edit the following two files and reboot!
- The secondary wireless network MUST be on a different address range than the host network. If this isn't what you want, you may want to research 'wireless repeater bridge', but I haven't tried it.
- To make sure your setup is working, run `ifconfig' to see if wl0 has an IP address from the upstream router, and `iwconfig' to see if the Linksys is associated to the upsteam router.
- If you run `brctl show' you will see that eth0.0 and wl0.1 are bridged.
- This configuration is apparently BROKEN on Kamikaze 8.09, 8.09.1, and 8.09.2. It WORKS with Kamikaze 7.09 and Backfire 10.03.
- The "magic" comes from the fact that the Broadcom chip really has two wifi interfaces that can be configured to work independently: one as an AP and the other as a STAtion. This functionality is only possible with the brcm-2.4 series firmware that includes Broadcom's wl driver, not with the brcm-47xx series firmware that includes b43.
