Hi, I have just switched isp's, before i had DSL internet and i would just connect my router to switch and my Ethernet ports around the house were working. Now that i have switched to cable internet, the cable modem(upstairs) is too far from the switch(downstairs). How would i go about connecting my cable modem to my switch thats downstairs so i can use my ethernet ports in my house?

do you have a network outlet in the room where the cable modem is that is coming from the switch?

if so, connect the modem to it.

I do not have a network outlet in that room, only just a regular ethernet jack. I did try using that jack but it did not seem to work.

What is the model of your cable modem? Does the ethernet jack go straight from the room the cable modem is in to the room the switch is in?

My cable modem is a Hitron CGN2-ROG, and yes the jack goes straight to the switch.

When you hook a wired device straight to the Hitron, it works fine?

If there are 4 ports on the back of the cable modem you might need a crossover cable depending on the age of your switch or see if there is a uplink port on your switch. What is the model of your switch?

Does your switch show a link light on the port you connect from the router?

I have tried using a regular cable and a crossover cable on each port with no luck. my switch is a D-Link DES-108 8 Port Fast Ethernet Switch

My last thing would be to take a laptop use a cord and plug from the laptop to the switch to ensure it is working and the lights light up, then next would be to plug the cable that goes to the room where the router is into that switch and plug your laptop into the wall there and see if any lights come on. If no lights come on remove the wall plate and check the cabling out.

Ok dont know if i should start a new thread for this but here goes, i fixed the cabling in the wall closest to my cable modem. The modem lights up so it recognizes the port and my switch downstairs also lights up and im confident now that my modem and switch are now connected. The trouble is now that whenever i plug in my laptop or ps3 to any port in the house i receive no connection i dont know what else to do.

What if you plug your laptop into the switch? Do the other ports in the house have the wires going to the jacks or are they also like the original one you worked with?

The other jacks work because i use those same jacks when i had dsl internet, the switch lights up whenever those jacks are in but no access to the internet with this new cable internet

if you plug your laptop directly into the cable modem do you get internet? What IP address does your cable modem give you?
