Get rid of XP, 802.11ac works ok from windows 7. Check your bios.

I made the upgrade on lenovo t60 802.11ac. Works fine with fn+f5. One new discovery is that battery increased a lot with wifi, before i had like 2h on wifi, now its 4h+.

This should work on all T60 T61 etc 1. Half mini-pci to full mini-pci adapter http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=191174599951 2. This was more expensive on ebay than my local shop.

Better u upgrade to 802.11ac card in your t60 as i did.
