    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!

    That's odd, because I'm assuming you're downloading over http/ftp which is TCP based, and should ACK for all packets, hence no problems. Something is bad wrong in that interaction, and it has to do with how that AP and your MB are playing together. I've used MB/MBPs before on wireless with no issues, but never with a 3com AP. Hopefully somebody else can chime in here.

    Yeah it's odd.

    But according to wikipedia, the TCP checksum is weak:

    I hope I won't have to get a new AP. The 3com is small and blends nicely into the livingroom, unlike the black/blue/green monster looking linksys'es.
