What should I do if only 1-2 ports on my router work?

Question

I have an ethernet LAN set-up in my house to split an internet connection 7 ways. We have both a router and a switch connected to high speed cable internet. All of a sudden, most of our ports stopped working (on both the router and the switch!) Any ideas? THANKS!

Answer 1

If you have dynamic IP then try to just unplug your modem for 2mins same as for the router, then plug the modem first then router next see if it gives you new address, if not try pinging your router see if you get any reply back if not then your router could be the culprit.

Answer 2

All of it stop working????

First, you must check is the electrical supply to both device is on. :D

I know it sound silly, but that is always the case, but better be sure.

Then, if the electrical supply is there, check if the switch port light or the router port light is blinking. If there is a blinking light, it means there is an activity, if not light is on or static light, it means something wrong.

Then, find a good, tested patch cord cable and connect a pc/laptop to the swithc/router using the cable directly and see if there is any blinking light activity, if there is still none, it means the switch is spoiled. Must go and get another one, this is possibly due to power surge. Home user never use power regulator on network switches, which is cheap and save a lot of problem and hassle.

But, how do you get access to the NET to ask this question this morning?

Answer 3

Get a small switching hub. Plug it into a working port on the router. Plug any other cables that used to be in the router into the new hub.
