Yes, that works fine, for IP management you can use your router's DHCP server do the job, or manually configure each device.
I usually let the router auto assin IP's then I will perma assign them in the rouers config if need be. I just wasnt sure if taking the one remaining port on the router and attachin it to a 20 port hub would work and not cause any issues.
Now that that's out of the way...
Anyone know of a ggood 20 port ethernet hub that can be wall mounted with front facing ports kinda like this USB hub ?

So there's one port left on my wifi n router but I need at least 6.
Here's my question, if I havee one remaining port on my router, can I take say a 20 port ethernt hub and wire it to the only port left on my router effectively turning it in to 20 ports or will there be IP issues ?
Of course! You just whap on as many hubs as you like... just don't create loops.
Loops ?
