TS already has a internet connection + wireless router at home. All he needs is either a PCI / PCIE wireless adapter or a USB wireless adapter dongle to connect to his home wireless network. The only thing that needs to be confirmed, is which kind of signal his wireless router is using, which is A/B/G or N-draft. Once he knows the signal type, all he needs to do is getting the right adapter for connecting to his home wireless network.
Recommending a BBoM is not in the right direction for TS. Additional subscription for another wireless connection where he already has one? :nono:
