Airport signal fades and is inconsistant on ibook
I use OSX.4 with Extreme base station with a imac and ibook - imac has airport card, ibook has extreme card. I noticed the bands from my airport would show full signal then quickly fade to 2, sometimes 1, sometimes none.
I put in a new extreme card, changed channels, re started everything, and traded in my old RCA cable modem for a modern one. no luck.
I took my ibook to work where everyone uses wireless, and it did the same thing, so I am ruling out interference. My imac works fine. Everything is pointing to my ibook. The only thing I can think of is a bad update.
Could a date, virus, or bad update caused this problem?
