Planning a surprise for Mother this weekend and want to arrive with a wireless router. She currently has desktop which is hardwired to modem. Pointless being a laptop really - so thought I'd be clever and link her up to be wireless. Is it that straight forward? She is broadband with Orange. Do/can I purchase 'any' wireless router? or will I need a specific one? Was looking for the most inexpensive one - have seen a few in Argo and PC World - chosen because I can buy them tonight!
