Most random problem I have ever occured.

I have ran into quite a unique problem that I am baffled by. I have a Toshiba Qosmio F45 with a major LAN card issue. I have a RJ45 drop on my desk that I use every day to plug my (Gateway) laptop into. I tried plugging the Toshiba into the same drop and it gives me the error of "Network Cable Unplugged". Hmm, so the drop works for my laptop but not the Toshiba. So I took the laptop to 2 other drops in the office that are both hot on my laptop but on the Toshiba I get "Network Cable Unplugged". Really strange huh?

Here is what I have done on the Toshiba.

Uninstall (Realtek RTL8101E NDIS 6.0) Driver. Reboot machine bring it back up, install new hardware, reinstall driver.

Go to windows update. Get newest update for LAN card.

The Toshiba is running Vista Business Premium.

Also spoke with Toshiba this morn and went through everything with there support personal and still could not resolve the problem. They wanted me to ship them the laptop and spend $400 to fix it. No thanks..

Tried all of them with no luck. One thing that gets me is the NIC is not even lighting up. It had 2 status lights one amber and one green. Neither of them are lighting up when plugging the hot cable into it.

Here's another wrench i am going to throw in there..


I got a Linksys switch, plugged a RJ45 into the switch and the other into the Toshiba and it sees the NETWORK CABLE now. Why would it see the connection on the Linksys router but not when I plug it into a known good RJ45 drop?

Try this, go into the BIOS and set the nic to be bootable (first in list). Reboot, and see if it trys to pxe or get a dhcp lease. If it "tries" you should at least see activity on the NIC if it doesn't than that NIC might be toast. But if let you install the drivers for it, than hmm. I dunno.

(didn't see that you "fixed" it)

You need to run tests on the line.

We bought a 2k tester fluke and detects all kinds of shit. I had the same problem before with a desktop and laptop. It said there was a kink 46% the way. Hell they had one unit that would tell you if you were close to something interfering with it. Its awesome.

Well, his earlier post states it works on other laptops/hosts. Plus he tried the laptop on other drops and it failed to work.

I say f'it and get a PCMCIA/USB/Whatever NIC and call it the day.

Hey hunt, what model is the one you have? I've been needing something like that and I am not about to go trace cables underneath the datacenter.

Update..

I went to the ADVANCED tab which filled the screen. I found a setting called Auto Crossover Detection. It was set to disable. I switched it to enable and the line immediately came up and has been working fine all morning.
