Hi all.I'm having trouble starting my wireless connection. I cannot detect any wireless networks, and it seems the problem is from the WLAN service. I tried starting this service but it fails. It reports in the event log that the Ndisuio service is probably not installed. I guess this service is required to start the other one.I've search the whole web for a solution but i cannot find any. I have a Ndisuio.sys file in my drivers and the ndisuio.inf file in the inf folder but i don't have any service named Ndisuio.Can anyone assist me with this problem?Thank you.

Plenty of Google hits if yousearch for'ndis usermode'

The thing is i can't find this service neither in the services nor in the registry.can i somehow reinstall it?

if you right click on the .inf file it gives you the option to install ithope that helps

Hi, I suggest that you try to repair that service from Registry. 1. Launch Notepad. 2. Paste the following content into Notepad.
