On installing SP2, after the reboot my wireless network adaptor is no longer recognised.
In Network Diagnostics etc the network card cannot be found, let alone fixed! However, in Device Manager it is apparently working fine.
Further reboots didn't fix. The only solution was to use System Restore to get rid of SP2. Instantly on reboot all was happy :-)
I guess I can live happily without SP2 for the moment, but wondered if anyone else has had a similar problem, or has a solution? Dell Inspiron 1525, running Avast antivirus, with Intel PRO 3945/ABG wireless card.
I found after SP2 that it took ages to connect, about 2 to 3 mins, even after several starts. Fixed mine by right clicking the wireless icon and selecting "diagnose and repair". It found no fault but offered to send report, I accepted. and it's been perfect ever since.
Got the latest Intel driver, re-installed SP2 and still have exactly the same wireless card issue. According to the Intel diagnostic tool, the card is "disabled or not present", but according to Device Manager it is working normally. The Windows 'Diagnose and Repair' can't fix it. Any further thoughts? Thanks!
Spent an hour on phone with Dell guy, who recommended BIOS update. We actually did that while I was on phone - it hasn't fixed it. In the end (after a lot of other fiddling around) he said it was a Windows problem and there was nothing more he could do. So I am now rolled back to pre-SP2 again and biding my time! I wonder whether re-installing SP2 *on top of* the BIOS update (rather than the other way round) might help. Does it sound worth the bother?! I will also keep installing other Windows Updates and see whether anything else makes it worse (or better). Thanks for all your help so far, do let me know if inspiration strikes.
