I have a 2 computers running off a wirless router. One is hard wired in. And i run my Mac book through "Airport". I have set it up that only these to computers can use the router by adding them using the MAC address to allow access. I have just purchased a Ipod touch. I have added that to the allow access using the MAC address. But since I did that my Mac Book runs either really really slow. Or does not work at all (connecting to the internet). I tried my hard wire computer and it runs fine. Normal no delay at all.
I have since taking off my Ipod touch from the access menu and my computer is running really well. Back to normal. Does anyone know why this is ????
