so i bought my MBP about 3 months ago. i noticed that the mbp's wireless connection was REALLY slow, so i automatically thought it was my d-link router. the wierd thing was that the G5 in the far corner room had no problems with the wireless connection. the other strange thing was that my mbp works perfectly on the wireless network at my workplace. but since i didnt need the wireless connection on my mbp that bad at the time, i would just directly connect the ethernet cable, and it worked fine. well, now the wireless connection is very important to me, since i move around from room to room. i went out and bought a belkin router but had the same problem. then i bought a airport extreme, but it has the same problem. when it is directly connected to the router it works perfect, but the wireless is really slow, ie. yahoo.com takes at least 30 seconds to load, or apple.com takes around 2 minutes to load. could it be a virus? could it be my network card? why would it work at some places and not in others??
