Hello,

My wirelss worked smoothly until today. Now Vista doesn't detect any wireless networks (my other laptop detects them on the same location). Diagnosing several times this problem always gives the following message: 'The Windows wireless service is not running on this computer', suggesting to 'Start Windows wireless service'. The next message is that 'Windows cannot resolve the problem'.
I have restarted laptop several times, checked with device manager all relevant devices that are enabled and working ok, then disabled and enabled wireless network adaptor and wireless switch several times. Checked firewall, internet properties - no changes from any previous settings detected. Checked the long list of what to be troublshooted per Windows' recommendation.

I could not do system restore because it was not activated by default and i didn't do any points manually (a new laptop). So, now I could not roll it back, unfortunately. Restoring to the Last Known Good Configuration didn't help.

Please advise how I could fix this issue. Thank you very much.

Configuration: Sony Vaio, Intel Core 2 CPU, 2.17GHz, 32x
Windows Vista Business

Hello, and welcome to Geeks To Go.
Lets look at the most simple things first, could the switch on the side of your laptop that turns the wireless adapter on and off have been switched to the off position by mistake?
Please look for the switch and note what position that it is in.
Thank you.

Thank you for your answer.
I have tried to eliminate obvious things and checked wireless switch several times, switching it off and on. So, it is not an issue.
Today I have also cleaned the registry with XP Repair Pro and optimized it, checked disk for errors and defragmented.

I also noticed that CPU usage is running unusually high since this wireless problem - idle CPU is about 80%, with dwm.exe and explorer.exe consuming about 32M of memory each.

Sounds like you may have some malware issues.
When ever the idle cpu is that high a lot is running in the background. If this is new then it is probably malware.
please post in the malware forum.
Thank you.
