Try the settings you want and consider adjusting if you have problems. In external programs, I have tried all options, and in advanced settings, I have tried ralink_legacy (I am using a rt2570 linksys wireless adapter) and wext, none of which work.

Troubleshooting Encryption Unless you have specific reasons for not doing so, you should encrypt your wireless connection. Is it possible that when dhcpd starts that wlan0 does not yet have an ip assigned, then gets one later after dhcpd has already given up? I have a Alfa AWUS036H adapter and neither the Alfa or my laptops internal wifi card would connect. Since your wireless is working (through the same router?) it probably won't help.

Connect Using the NetworkManager Panel Applet With the driver loaded go to the panel applet. Madwifi driver needs to change to authmode 2 when using shared key setting. I have Wicd as my network manager, and upon plugging in my ethernet cable, a wired option becomes available for network connections. A router reboot has been noted once to resolve but in other situations has caused heartache as network settings need to be set up again.

I am currently sharing this office with an udergrad and his Windoze machine connected to the wired network without a hitch.
