RE: Intermittent Network Connection Problems after XP



i am having a similar problem recently

periodically IE loses the server connection
often just after bringing laptop out of sleep mode

sometimes it happens when i try to open a new browser window
it wont connect but the old window still connects fine

however NetTransport is happily downloading in the background !

Firefox browser will not connect (same as IE)

repair connection has nor effect

only solution is to reboot

running win xp sp2 fully updated
connect by wireless LAN
sony laptop VGN-S3XP
use zonealarm but not windows firewall
(but disabling makes no difference once problem encountered)
virus checked with AVG Spybot AdAware

any ideas anyone - how can i even start to diagnose ????
