//As far as I am aware, the devices I linked to and recommended simply provide extra ethernet ports at the router. So if you had only one port free you can use these to give more ports for extra cables but that device has to be plugged directly in to the router so all the cables you needed to connect would have to reach the router//
I'm missing something here hc4361. I understand that the device may be nothing more than a glorified ethernet extension socket for mor cables, but I fail to understand why the device needs to be in close proximity to the router. Surely, within reason, if the device is connected via an ethernet cable to the router, the cable length is immaterial? Does it really matter that the device would be in the next room to the router or does the signal in the ethernet cable degrade in some way preventing optimum performance of the device?
