Ethernet cable not connected

March 7, 2010 at 00:59:30
Specs: Windows XP Version 3, 512MB
I am attempting to connect to the net via my ( 6 year old ) desktop PC.

I have followed all the instructions and all the lights on the router that the setup page says should be on are indeed on. Yet, despite the fact that the Ethernet cable is correctly inserted into both the router and the PC, and the light is lit, the setup states they ar enot connected.

I have rebooted, restarted, rechecked and rechecked but it will not recognise this connection.

Any help, you good good people?

Thanks
Ste

Could be the wrong type of cable. From PC to router you need a straight or patch cable. If you are using a crossover cable you will not get a connection.

The cable came with the router so I would assume that it is right?

Not necessarily if the cable is meant to be used between modem and router. That cable would be a crossover configuration. Was there any documentation with the router that indicates the cable type?

It doesnt say, annoyingly. Just says Ethernet cable. Any clues as to how you can tell the difference by looking at it?

I have realised that also it talks of a "wireless adapter". Forgive me but I do not know what one of these is nor do I know whether I need to buy one. So I guess this is two questions in one, sorry!

Thanks again, I appreciate your help.

Have you confirmed that the Network card is actually installed correctly? Look in Device Manager.

Do you have a Wireless card in the computer? More information would be helpful.

I'm having the same problem with a new install.

PC says cable unplugged. I've tried XP and Win 7. Same
issue. I've tried multiple driver versions -- same problem.

I've tried different PCs on the same cable -- they work fine.
Clearly, not a hardware issue.

Interestingly, if I install MINT (Linux) or use the ASUS
Express Gate (or whatever they call that mini-OS thing), the
PC connects fine. So, it's got to be a driver issue or some
sort of system conflict.

I've messed with all sorts of settings on the controller
(RealTek onboard LAN controller) including the power
management ones and the speed settings. Nothing worked.

I'd sure love some help on this.

Thanks

Not so. A crossover cable is only required when connecting like devices. Which is to say, if you're connecting one PC directly to another (ie: NIC to NIC) or one switch to another. Although in the case of modern switches which are "auto MDIX" capable, that's not absolutely necessary, although I always recommend it.

A modem and a router are two different devices and as such, a regular (straight through) patch cable is all that's required.

For the Original Poster and sumgai:

First, do as Jennifer said and ascertain if your NIC is actually working correctly. Check in Device Manager.

Confirm you have the correct cable (compare both ends are the wires exactly the same - if so, it's a "straight through, patch cable"). If your NIC appears to be working properly and you have the correct patch cable and it's still showing the NIC as not being connected, try another cable. Preferably one you know is working.

If you suspect a driver issue, go to the manufacturer's website and download the most recent version and install it.
