I don't currently have an interconnection at home. If I want to set up wireless Internet at home with a router / modem do I need a PC or Laptop ? Can it be done via an iPad ? Basically I want to run iPhones and iPads from the service. If I need a computer can anyone recommend a cheap reliable one ? It would only be used for surfing the net, using MS Office programs. No gaming or anything like that. Thanks in advance. Oh an while I am not a complete tech numpty, keep it simple please !
