I'm having problem specifly with a HTTP protocol, the symptoms:

- Images JPG load bad (load 50% good and 50% bad , I can see that).
- Files(>1MB) download are corrupted, (crc error in a zip rar, or corrupted)
- When I try find somthing in google , sometime I see only just character
like "·$%&/("
- WEP encrypted wireless don't work
- Web WindowsUpdate don't work
etc...


This problem only ocurred when wirless is active. the connection direct
using wire , all is fine...

The browser Iexplore is fine too, because I experimented same problem with a
Mozilla FireFox

update Sp2), I installed SO 2 time , for secure,but this ocurred two time
!!!
