Suddenly, i got my wireless adapter on my lap ran slowly, very slowly, then can not connect any wireless network anymore. Diagnose makes no luck.
Properties on any network adapter just give a message "An unexpected error ocurred". Can not disable or enable adapter by using network connection management windows.
My ethernet still works well but it dosen't display any information in network connection windows, even it's been connected.
I dont have enough free disk space to do a repair install, so i do a post here to see if anyone can help.
