I already have a Netgear WGU-624 Router connected to my modem and I have a 100ft ethernet cable running from it to a room. Right now my computer is connected to that cable, but I would like to get a router for it and then plug my computer into that. It needs to be reliable because I host a server. I will also be hooking up another server to the new router. I'm looking at a price of about $40 max. 4 ports is plenty. Any good candidates?
Also, if I understand correctly, I wouldn't be able to run servers through a switch and therefore need a router.
Your router is actually a router and a switch if it has a few ports in the back of it. The router handles how your traffic is sent out to the internet and hands out DHCP, the IP addresses to anything it is attached you or searching for a DHCP Address.
An unmanaged switch (to get further into it) does not require an IP address. A managed switch, meaning you can really tweak settings on the switch itself, will require its own IP address. That's high end stuff and very costly though.
