Can anyone give me some advice ?
I recently switched to the 20 mb cable service and have 2 pc,s 2 laptops and 1 x box connected through the Belkin N1 router (5000uk version).
All work fine except 1 of the laptops which is a macbook every time this mac connects my speed to the main pc drops down to all most no connection,and the x box drops all together?
I have checked and there is no firmware update as of yet.
I,m just wondering if there is anyway i can split the connection between the macbook and the other laptops and pc,s ,so that the mac cant get all my connection speed?.
ps if anyone knows of a way to limit the traffic to each pc, laptop, say 5 mb each that would be ohhh soo helpfull!
Oh btw i dont have all said items running at the same time before anyone asks!!!.

thanks for taking the time to read this post
