Hi all, I have recently bought to airports, both are the same the plug into the wall although different model numbers. I have been looking for a while now on how to set this up as no set up guide or instructions came with them. All i want to do is set them up to boost the wifi around my house for when i get my ipad and possible Apple tv. What is the best way to set these up? i have plugged one into the wall and the ethernet cable from my existing sky wifi router going into this but all i am getting is a flashing orange blip. please help
