Hello everyone-- I have a user (Housemate, don't you know.) with a problem that is evidently of my making. She was unable to log on and I fixed the problem. So fine and great -- but then I rather stupidly swapped out one wireless N.I.C. for another, and then swapped them out again (I was checking to see if the second Wireless N.I.C. would automatically work like the first Wireless N.I.C. -- it doesn't). Now the wireless bars in the top right of the screen show no signal being received, but when I hover the pointer over the wireless bars, the message that pops up indicates fifty percent (50%) signal strength. Needless to say, the browser is now unable to log on. Any ideas that can be offered as to what might be wrong will be greatly appreciated! --N.B.
