I tried to wirelessly connect my T61 with a netgear router last night. Could not do it. Netgear had me go to: CONTROL PANEL/NETWORK CONNECTIONS, and there were NO ICONS appearing in the big white box under NETWORK CONNECTIONS.
They then had me go to DEVICE MANAGER/NETWORK ADAPTERS, and I am able to see: a) 1394 Network Adapter, b) Intel(R) 82566MM Gigabit Network Connection, c) Intel(R)( Wireless WiFiLink 4965 AGN.
So my computer does have these connections, BUT they do not appear in CONTROL PANEL/NETWORK CONNECTIONS, for some reason.
