Sorry this has probably been asked before but only have access to the forums using my phone atm. I've always used a wired 56k/broadband/cable Internet connection. I now have sky broadband and need a wireless receiver for my pc. The supplied router is only wireless g. My ps3, even only g, is plugged into the router so that's fine but a few mobiles in this house are also g only. Firstly should I get wireless n for the pc just for the future? Also is it best to get a network card rather than USB? I have spare pci slots and a 4x pci-e slot. My motherboard is an ASUS p7p55d le which is USB 2.
