Network Cable Unplugged

[germouse12]

I recently bought a Network Everywhere Fast Ethernet 10/100 5-port hub and was having a problem when i tried to connect it. The light on the uplink port, where the cable modem is connected, was on but the lights from the computers weren't. The computer says a 'Network Cable is Unplugged.' The computers were both on. The computers were plugged into wall outlets that have cat 5 cable going through the walls of my home to a central location where i had the cable modem and the hub.

When i plugged the computers into the modem via the house cabling it worked fine; i had a connection.

When i put the hub next to the computers and connected them directly it worked perfectly, both of the LED's were lit. The cabling through the house is less than 100 m and for all i can tell the cords aren't coiled at any point.

Is it a problem with the hub, house wiring, other?

If you have any ideas as to how to get it to work properly that information would be much appreciated.

Thanks

PS I have supplied a drawing to help

Take it back and get a router. I have a D-Link 714 P.

This router has 4 ports for wired and if you ever decide to get a laptop and go wireless you've already got it.

A hub is not the way to connect multiple computers to a broadband connection. You need a router, which will assign an IP address to each computer on the network, and connect them all to the net, with the ISP seeing only one connection (the router).

Personally, I like the Dlink products, like the DI-714P+ mentioned above. I've been using a DI-707 to connect my herd to the net for a couple years now

yeah i was thinking about that the only promlem is even without the cable modem plugged in it still isnt recognizing the computers

So, even when you plug only the two computers into the hub without the modem it still doesn't light up? The only thing I can think that might be a problem is, check the wires to see if they are 'straight-through' wired or if they are 'crossover' wired. If they are crossover wired then the wires would be a different configuration on one of the jacks, in other words, each of the eight wires wouldn't be in the same position on the RJ-45 jack.

That's the first thing that comes to my mind. If they are 'straight-through' wired, then that's good. Let me know, and I'll give you some other things you could try.

yeah im pretty sure they are straight through so i dont know what the problem is. i cant look into the wall outlet but im pretty sure it isnt crossover. thanks alot anyway though. any ideas like that could help.

The wall plugs must be miss-wired if the patch cables are all striaght through. If it works for each wire for the cable modem and not for the hub, then it sounds like either the patch cables (from wall plate to hub or PC) are X-over, or the wiring of the wall plates themselves atre X-over. In that case, try connecting the PC's with X-over instead of straight through cables. That'll fix it.

Another thought: can you test all the patch cables (ie test to the hub directly without going through wall wiring) to see if they all work?

It worked!

I recrimped the wires as crossover and lights started up all over the place. Thanks a lot for all the advice. You guys rock!
