Added (1). Hi everyone,

I came across this used Lenovo Thinkpad T420s laptop on Ebay that I want to buy, but while reading the description I noticed that on that of the Networking, the seller listed Networking Type as Bluetooth and Data Link Protocol as Bluetooth too and I can't find any information about IEEE 802.11b/g/n WIFI connectivity etc.

Now I want to know if this Laptop can connect to router WIFI or other wifi network devices that does not have bluetooth or can WIFI network adapter be installed?
