I just installed W7, and now when I try to connect to the internet it is telling me that I need to plug an Ethernet cable into the computer. Well there is one plugged in and I don't know what to do. It seems that it detects the modem, I'm unsure if this is a driver issue or what. I have a Realtek RTL8139/810x Family Fast Ethernet NIC.

Glad to find a forum that's devoted to Windows 7, nice to meet everyone and thanks for your help.

It tries to connect to the internet (which it can't do) and then says I have the best driver.

Unfortunately, installing the driver didn't do anything. I checked and it is set to Auto-Negotiation. The error that I get is Error 651.

Thanks for helping everyone.

So, I'm still without the internet. I believe my main issue is still the fact that it tells me there is no Ethernet Cable in, and the light on the back remains off (instead of the usual green, or orange).

Solution

I was having the exact same issues with my ethernet controller but after a long and arduous struggle I seem to have found the frustratingly simple solution:

The driver may (or may not) be the problem, so for completeness I'll mention that I downloaded the Realtek drivers that I'm using from here:

Download Realtek Ethernet Windows 7 Driver v.7.003.0622 | Catalog - X-DRIVERS.COM: eXtremly full software portal

(Realtek PCIe FE Family Controller ver. 7.3.522.2009)

THEN:
I simply went to the device's advanced options tab (by right clicking on the device in the device manager and selecting properties->advanced) and enabled the auto crossover detection which by some obscurely spectacular blunder is disabled by default...

Hope it helps :)

Solution

I Had the same Ethernet cable problem, nothing seemed to help. My network adapter, an NVIDIA nForce is integrated in the motherboard (no details available in Device Manager).

1) I disabled the built-in network card in the BIOS Setup and installed an old 10/100 in a free slot. Windows 7 recognized the card and cable and suddenly I had network and Internet access via the router.

2) Shut down, take out again the slot network card, plug the cable back into the built-in socket

3) In BIOS setup, enabled again the built in network card

4) Everything now works, no idea why.

I have installed Win7 as dual boot with my existing XP, which I have connected through a Linksys WRT54G router to a modem for the internet. On XP, it is and has been working for a long time. However, on the new install of Win7, it advises that there is no cable connected to the NIC. I have tried the network troubleshooter with no luck, but being new to Win7, I don't know all of the in's and outs. This PC is connected via wire to the router, with a 2nd PC connected wirelessly.
