I have a Lenovo T 61 unknown wireless adapter and my wireless worked in v 12.04 but no longer connects with v 12.10, what should I do to resolve this problem?

The T61 was sold with four different wireless cards. Please run lspci -nn and verify yours before you apply any fix. If in doubt, post it here and we'll help. – chili555 Nov 27 '12 at 13:24
