I'm having a Cat6 wired network installed at my house. There will probably be 20-24 cable runs that all terminate in my basement in a room with a coaxial cable connection for Comcast internet. What router should these connections terminate in that will be quality and yet won't break the bank?
Get a 10/100/1000 Mb 24 port switch. Connect whatever Comcast gives you for a modem lan port to one of the switch ports. Their Modem/Router combo will provide DHCP for your network. If you need/want wireless in a location, just get an access point and set that up where needed.
Good to ask at this point in time. Suggest extra cable runs to office and entertainment areas. (I disabled - removed my isps router in the basement and run my own upstairs - I prefer the router in the home office.). Still use their modem though. Definitenly a switch and UPS in the patch panel where all the wires come together.
c) what kind of features do you want for the router?
A 24 port "router" doesn't exist at the consumer-level space... at the enterprise level, you're looking minimum 4 to 5 figures easy. As aguen says, get a 24 or more switch, leaving one interface free to connect to the ISP-supplied or your preferred router / modem and go from there.
