Just wondering if anyone ever installed one of their own and was it much hassle?i get the broadband through an aeriel and its pretty much just plugged straight into the pc.i know thats not a very technical explaination but thats how it appears to me!!i want to get wifi in as the missus wants a laptop and it be handy for the smartphone too cos the mobile web aint the best in the house.ive the broadband in with ripplecom and theyre not doing any wifi till they get new routers in in january but said if i wanna fire away with one myself to work away.so after all that waffle im wondering are they hard to install do i need a certain type and are they dear?
