Today I tried to connect my desktop wireless to my home network (updated PASS)
Standard this box is wired connected to the net, but I need to demo on saturday..... wireless.
Both Ralink, 54g and 150n, a nogo.
First tried TerryN's solution, all SSID's vissible but no connection.
Next installed conform this thread:
rpm -Uvh --oldpackage wpa_supplicant-0.7.3-1pclos2011.i586.rpm
(With --oldpackage it's a forced downgrade + networkmanager is not removed)
Problem solved.
For checking I installed the 1.0-3 version again and rebooted.
The system came up connected.
After a manual disconnect I could not login again

So back to the 0.7.3-1, succes.
Tested with both USB sticks:
Ralink 54M.USB......
Ralink 802.11 n WLAN
As side effect I tried ndiswrapper, but always greated with, can not find ndiswrapper interface.
