When I download large files from the internet through my 3com AP, they tend to be corrupt. It tends to be files of more than 3MB or so. When using ethernet instead of wifi, there's no problem. I never had that kind of problem with my previous g3 and g4 mac laptops, nor with my old PC laptop w/ a wifi pcmcia card. I updated the firmware on the 3com AP, but the problem persists. Any suggestions to find out what's wrong? Should I run some app to analyze the connection or something? UPDATE: I just tried downloading something through a Linksys router, and it also failed verification!
