I was wondering if anyone can help me with a few upgrades I'd like to do to my home network. Basically, I'd like to go from wifi to hard wired connections for all of the equipment in my upstairs den. I think I will need 5 ports max. So can I get a 5 port Ethernet switch and plug everything into that, then run a single cable from the switch to my wifi router? Any suggestions on hardware? I have (supposedly) gigabit fiber internet so I would want a gigabit switch I guess.
