Need help connecting wireless router to in-wall network

Recently moved into an apartment that is wired for ethernet. Each room has a wall jack, and the other ends all terminate in a panel in a closet. The panel also includes an 8-port hub/switch.

I have a cable modem, which currently connects to a wireless router. I would like to have the modem connect to the router as well as the in-wall network, so I can use the wired connection in a room that isn't getting good wireless reception.

It seems like if the cable modem is connected to one of the ports (either directly or via the router), it should be possible to use the closet hub to activate all of the others. So far no luck.

Here's what I've tried:
Cable modem wired to uplink on router; router out to wall port, pc on different wall port
Cable modem wired to uplink on router; router out to wall port, pc on closet hub
Cable modem directly to wall port; pc on different wall port
Cable modem directly to wall port; pc on closet hub

The best I can do is having my laptop recognize a connection from one of the wired wall ports, but then the connection immediately goes to "limited or no connectivity".

There is no cable jack in the closet area, so I can't hook the cable modem directly to the hub in that panel.

Do I need a cross-over cable somewhere in the system to make this work, and if so, where in the system would it go?

Any ideas on what I am doing wrong?

Thanks

Put the router into the same room as the cable modem. Plug the cable modem into the WAN port of the router, then run a cable from any LAN port on the router into that room's wall jack.

Run a patch panel from that room's patch panel port to the switch. Repeat for each room you want to connect from.

That should be it. "limited or no connectivity" almost always means no DHCP reply. This would happen if the cable modem were connected straight into the apartment wiring and had already attuned to a specific device's mac address.

Shouldn't need a crossover cable as long as your router and cable modem were made in the last 5 years.

Well whether or not you need a crossover cable depends on whether or not your router and switch are auto sensing. My home is hard wired with a panel in the master closet which also has cable and phone jacks for broadband. I use cable so my network looks like this: cable modem to wan port on d-link dgl-4500 router - any port on router to any port on hp procurve switch then any port on switch to any port on wall panel which then populates all lan jacks in house. If I needed more ports in a given room then I'd take another switch to that room so I could plug in multiple devices. The router is what handles the traffic over the network. The switch just adds more ports up to the limit of the router. All of my equipment is wall mounted in the same area as the wall panel in close proximity for easy access.

The switch is to the network like a power strip is to a single electrical recepticle. It can add recepticles but you can't exceed the capacity of the breaker feeding it. You really need to ask the landlord to run a cable jack to that closet or get the cable company to do it so that you can connect everything properly.
