cannot connect via hub

[123gad]

I have a hub and 2 PC's, only one Network Outlet, what is working I tested it. When I connect the cable to the 2 PC's and 1 cable from the Hub to the Wall I don't get a signal, I tried already about 6 different cables, no luck.
I get the messge, no domain server is available... you may not be able to access the network...
I have done this setup a few times no problems.
Any ideas what else could be wrong. When I hook the PC directly in the Network Outlet it's working.
Thanks

I am guessing there is another network device at the other end of the wall socket, (another hub or switch or gateway) and that you need a crossover cable, or, if your hub has one, to use the uplink port.

Hubs are normally set to connect to end devices (computers, printers, modems, etc.) and need crossed wiring to talk to other network devices. Some hubs have uplink ports or buttons (often marked MDI MDI-X) so normal cable work, if yours does not (what model and vendor?) then you need a cross over cable. I tried to remain child-like, all I acheived was childish.

Jimbopalmer's right - take a look at cabling standards:
like-like = crossover cable
like-unlike = patch cable

so therefore:

wall socket : PC = PATCH cable
wall socket : HUB = CROSSOVER cable

What, if anything, is providing DHCP services here?

What is at the other end of that wallplate? Just a modem? A modem that provides NAT services?

 

[bcastner]

You did not specify, but if this is a cable service for internet you may have a MAC address cloning issue.

bcastner - I think the wall point is a simple RJ45 socket connecting 123gad to a LAN (as he's getting the message &quot;I get the messge, no domain server is available... you may not be able to access the network...&quot;)

which means it's probably not a broadband modem / dhcp / mac issue.

manarth,

Thanks. I kept seeing two PCs and a hub.

My guess(es) then, as between plugging in the uplink port or a regular port should solve any cable problem:

. The hub is bad. (use a switch anyway)
. Too many hops
. Cable distance exceeded or marginal. The hub is just enough loss on the cable segment to make the thing die.

I apologize for not being so clear on my setup. I have a LAN setup with about 12 PC's.
On one station I have only one outlet for a RJ 45 cable, so I did what I done a few times, try to put a hub in the middle, to use one outlet and 2 PC's, but everytime I receive the message no domainserver available to....
I bought a router yesterday and will try today if it works, I never used a router for this scenario.
Will a router work the same as a hub or switch?
thanks for any feedback this morning..

Your setup is clearer to me now.

You want to take either use a cross-over cable from wall-plate to hub, or plug the cable from the wall-plate into the hub's uplink port.


Whether you add a router or switch you still will have to deal with the proper cable, unless your new router or switch auto-senses MDX.
