I just got a 17" Powerbook G4 1.5 Ghz. My friend that sold it to me said that her wireless always had a really weak signal but in recent time, unless she was in the same room as the router it was really hard to get a decent connection. She said she took it to an Apple store but her Apple care was expired and they said they'd have to send it out for 5-7 days. Today I just tried it out at home, where I normally (as well as everyone else in the house) have full signal from our router, this computer gets a bar or two max. I was adding in some more RAM to it so I figured I'd take it the rest of the way apart. So, in doing so carefully because I could not find a diagram at all that matched this computer, I found that there is not a Airport Extreme card in the computer at all! So, since you guys know the answers, I have a few questions. Is that right? Is the wireless built in now? (or maybe for that year) Is this a common problem that the signal fades? What can I do about this? this kinda sucks! Any other suggestions!? Thanks for reading...hopefully somebody else knows this same situation and I can figure something out!
