Alfa wireless adapter and Ubuntu...
 

I got a problem whit my wireless adapter(AWUS036H) and ubuntu...
I know it a very power full adapter (at list it was on windows) but it seams on ubuntu it not that strong i fink it maybe im using a wrong driver or something.... and how i can swich off the keyring (all the time when i login i need to enter password so i can use an internet)

That's a bug with network manager that you have to enter key everytime when you want to connect.That's way I'm using http://wicd.sourceforge.net/.About your signal,I guess you need to search for a better driver if you haven't already.Use lspci -v command to see what you need,if you don't know.

Thanks a lot
