Hey, any of you techies shed some light on this? Windows XP home desktop SP2 (not gonna upgrade to SP3 just yet Wireless lan card NVidia 512mb graphics card Soundblaster audio card 1GB Ram Netgear wireless router: 1 wireless connection, 0 wired connections. WEP security on a 128bit encription AOL broadband silver i rarely use this machine as i've had my laptop for so long, i just let the kids use it, so i'm unsure when this started. i dont have this problem with my vista laptop, although its in the shop under warrenty at the moment so i cannot be sure. since this started i have: Changing the wireless channel on my router Changing my routers network key updated and ran Avast! antivirus. Scheduled a boot scan with Avast! ran disk check with both options checked (the one you access by right clicking c: - properties - tools tab - error checking) Updated and ran CCleaner. Updated and ran Malwarebytes Updated and ran Spybot Search and Destroy Updated and ran Superantispyware Updated and ran Hijack This, and submitted a report to the Help2go detective at www.help2go.com Checked for updated drivers for my wireless lan card Checked the Device manager for warnings or conflicts both before, and after this occurs. during the above things i detected alot of tracking cookies, but little else, and even after cleaning and re-running the scan (which was then clean) the problem still exists. The problem: At first i just thought this was a power setting, as if i left the computer running for a while, i would come back to a message saying "wireless networks could not be detected" which a quick restart solved. thinking nothing more of it, i just carried on regardless, then the disconection would happen in the middle of me browsing. suddenly all connections would drop, and no wireless connections are seen to be available, even though i know where are 3 in the area which i normally pick up. Only a restart seems to solve it, with the connection becoming available as soon as the computer reboots. This does not happen at an interval, and can last days before dropping, then drop twice in an hour. on startup all i have is my logmein software, avast, msn messenger and my firefox browser (because i only use this computer to browse the internet and store photo's, it seems sensible to have these start then.) as well as the normal startup stuff such as nvidia drivers, sound etc Any ideas where to look next?
