Specs
Wifi adapter: D-Link DWL-122 USB
Driver: prism2_usb (from wlan_ng package)
OS: Kubuntu Dapper
After fooling around with wlan_ng for an hour or so, I rebooted and launched
wlassistant. I was pleasantly surprised to see that it was detecting my wireless network, signal strength was reported as full, and it displayed the correct channel, AP MAC address, etc. I confirmed that it was detecting it dynamically by turning the router on/off and making sure it recognized it.
I configured wlassistant to use the correct WEP mode and key when connecting to my network, but whenever I try I get a "Connection failed" error. I've tried temporarily disabling WEP and MAC address access control to see if those were causing problems, but it didn't help.
So, it appears that the wifi adapter and drivers are working, but I still cannot connect. What should I do?
