Thanks KnoppMyth devs/contributors! You're amazing!

I'm trying to get a new Linksys wireless network controller to connect on its own at bootup. It's installed, configured(?) and active, but not connecting. What step am I missing? Are eth0 and wlan0 mutually exclusive?

Efforts So Far
Fresh install using R5.5. I followed the directions here to get it set up using /etc/network/interfaces and the CD that came with the WMP54G, but when it boots up the wireless doesn't connect to the router (wired does). Wireless does work when I use RutilT though!

I threw in the towel and disabled security on the wireless router and restricted access by MAC address. =/

I had similar problem trying to get WPA2 security for my setup. I ended up using a cheap Linksys WRT54G router converted to "client mode" using a Tomato - a 3rd party firmware.

It made for a slightly more bulky setup because it's one more device to stuff near the TV, and power socket used. However there are several advantages.

    1. Wired NIC's are pretty much supported by all Linux distros, so it's one less thing to configure if I need to reinstall, or doing test installs on a backup drive.
    2. I get much better reception using a router.
    3. I can see traffic LED's blinking.
    4. The router also doubles as a wifi range extender.
    5. I didn't have buy a special Tivo wifi adapter to get my Tivo online (it only has ethernet builtin).
