Yesterday I turned my computer on and Windows Update immediately started downloading and installing Service Pack 3, never giving me a chance to stop it (I learned my lesson - Automatic Update is going to be set on manual install from now on!). It downloaded Service Pack 3 over a wireless connection, and wireless has been working fine on this computer for the four years that I've had it. After Service Pack 3 was installed and the computer rebooted, my wireless does not detect any wireless networks whatsoever, nor will it connect if I configure one manually. I live in a college apartment, so normally I can see about 5 or 6 networks in addition to my own hidden one. Device Manager reports that the card is working fine, there are no obvious error messages in the system log, and I can't find anything wrong with the card's settings - it just refuses to detect any networks. Below are the measures I've taken up to now in attempt to fix the problem: First I uninstalled the drivers, then installed more recent drivers directly from Intel's website. This didn't work. Next I uninstalled Service Pack 3, uninstalled the drivers, rebooted into diagnostic mode, reinstalled Service Pack 3, and reinstalled the drivers. This didn't help, either. Finally I uninstalled the drivers, uninstalled Service Pack 3, then reinstalled the drivers and am currently running without Service Pack 3. It still doesn't work. Yes, the card is turned on, both from the laptop's "on/off" button and from Windows. Somewhere in all of that I also downloaded and installed Intel's PRO/Wireless client. It didn't detect any networks, either, so I uninstalled it and have returned to using Windows to manage my wireless connections since I prefer it. Service Pack 3 and about 8 updates that came with it are all that changed on my system between "working" and "not working." I really don't know what else to do short of backing up all my irreplaceables and reinstalling Windows, which is obviously something I'd strongly like to avoid... below are my specs: Clevo M40AE ("Raptor406Z Reactor" from xtremenotebooks.com) ---------------------------------------------------------------------------------- 15" SXGA+ 1400x1050 LCD Display ATI MobilityT Radeon® X700 16X PCI-E with 256MB DDR VideoRAM NEW! 2.0GHz Intel® Pentium® M "Sonoma" Processor with 2MB On-Die L2 Cache - 533MHz FSB 1024MB PC2-4200 533MHz DDR2 (2 DIMM) 60GB IDE ATA100 HDD 7200 RPM 8MB Cache 8X24X10X24 DVD/CDRW Combo Drive with software (8x DVD/RW available) WOW! 12 Cell Smart Li-Ion Battery - Approximately 3.5 Hours of Runtime! 110/220V 150W Auto Switching AC Adapter - Included Sound Blaster Compatible 3D Audio - Included Generic Integrated System Speakers - Included Entry Level Black Vinyl Carry Case - Included Windows XP Pro SP2 with Drivers and Utilities CD Intel® PROWireless 2915ABG 802.11a/b/g - Standard Standard 12 Month Parts and Labor Mail-In Coverage Internal Bluetooth Wireless Mini PCI 4 in 1 Flash Card Reader (SD/MMC/MS/MS PRO) Standard Let me know if there's any more information I should share that could be helpful.
