I have a Lenovo Thinkpad Edge Laptop that when I connect to wireless it makes all my SSID's disappear on all other wireless devices.
System was on a Domain (Wired) but was responding VERY slow to public shares. It was acting like it had a virus. I took unit to another location. Performed Factory reset and wireless problem continues.
Router is apple time capsule. I have updated wireless LAN drivers, Bios, and chipset.
