I have a WRT54G Linksys router. It is also a switch And I have ran out of ports. I am finding myself in need of more ports. Can I just get a 5 port switch and uplink to it from one of the ports on my router.
Yes you may. It will work fine. The only thing you may run into depending on the make, is the need for a crossover cable for switch to switch hook-up. Some will auto-sense it, some won't. Check the web site for the one(s) you look at.
