Can't use switch with Router
The C6300 has 4 LAN ports, but I need twice that many. When I connect a switch, the C6300 appears only DHCP one IP address per port, leaving the rest of the switch ports dead. Is there a way around this?
I would rather not use a second router, since then I have to actively manage all the port forwarding.
Not sure what switches your using. Sounds like the ones you have are either faulty or you have bad cabling. Most any gateway modems only come with 4 LAN ports. Most modems you get support having a external LAN switch connected. From 5 ports all the way up to 48. Yours as well.
You might find a local computer shop to help out and see if they can help you get a proper Gb LAN switch connected.
Good Luck.

No.
What Mfr and model # switch are you using?
Try NG GS-105/108v4, D-Link DGS-105/108 and HP ProCurve 1400/1800 series switches.
If there is no solution, why would particular switches work? I don't understand. I tried two very old switches I had, but neither worked. I went to Office Depot and purchased a Netgear switch (don't recall the model - had four ports), but it didn't work. The I tried to use an old Netgear Prosafe that I had lying around and it worked for a week until it failed.
Be sure your LAN cables are of good quality. CAT6 is recommended.
ANY Gb LAN switch should work, unless you have a faulty unit, switch or bad cabling.

I don't know what "this" is. Connecting a network switch to a router
LAN port should simply work.

Out of the three switches I tried, they all had the same behaviour. The first item plugged connects to the wider network. Anything else connected to a port of the switch afterwards does not. If I have to supply a particular model number at this point, then I will have to go buy another switch. I got rid of anything that didn't work.
The C6300 is a cable modem with four LAN ethernet ports and WiFi. No idea what you mean by "configured."
"Connect" means that one of the ports on the switch is connected to one of the ports on the cable modem. Is there another choice?
I am using cables that are about three feet long. The pretty green lights come on at both ends, with occassional blinking even on ports that just spin their wheels and don't connect.
Why not give model # of what you have? Would be helpful. It's nothing private to be concerned about. Ther maybe a mis-configuration.
Just tring to help here. I know my C7800 has had switches behing it. No issues.
I've had a few switches connected to my c7800 series modem. Zero issues.
Good Luck though.
