This may have been asked before, so apologies, but without knowledge of correct terminology I was unable to find a related question.
The router provided by my ISP has four gigabit ethernet ports. They are all used up, but I could do with some more (I prefer wired networks to wireless).
Is this possible , I know I need more hardware but don't know what to look for.
The current set up is:
[ISP Modem] ---> [Asus RT-N66U Router] | └┄> Devices 1-4 (wired)
My research suggests I need something called a "switch". Is that correct? If so, how would it connect up to the existing equipment please?
