No ethernet connection Toshiba Satellite U500 notebook
I've carried out a clean installation of Windows 7 Pro 64-bit from Toshiba's restoration DVDs.
I now have wireless connectivity from the machine but no ethernet.
1. There is no ethernet adaptor showing in Device Manager.
2. The indicator lights in the notebook's LAN socket are showing when an RJ45 cable is plugged in and the router indicator light shows a connection.
3. I've re-installed the driver from Toshiba (tca0010800b.exe) just in case it was missed during initial install from recovery DVDs. The file executes but provides no feedback.
4. I've run SIW and PC Wizard 2010 hardware detection. Neither of these utilities show an ethernet adaptor.
I don't know whether or not the wired LAN worked before this clean install: I've never had occasion to use it before now.
Hardware fault?
Any ideas?

Thanks Nobus. Should have thought of that! I have Linux CDs by the truckload.

If it is a known issue, try the following:-
According to the comments of aleinss,
"Download SIW from http://www.gtopala.com/ and click on the PCI tab. Paste everything there into this question."

@ Jackieman
As I stated in my original question, I've checked with SIW.
It only lists one network controller under PCI and under Network Adaptors. That's the wireless LAN which works perfectly.

@ splait
The BIOS is updated.
@ edbedb
There's no option in BIOS to disable LAN.
@ johnny_the_knife
Latest chipset drivers installed.

I'm not in your time zone. I'm getting there. Tried 2 Ubuntu live versions, no LAN. I'm now downloading Knoppix.:)

Yes, I fear it's dead.
There was an "orphan" in Device Manager. It was PCI Simple Communications Controller. A google search indicated that this was the modem but Toshiba said that it was the ethernet LAN.
They gave me a link to the Intel(R) AMT Management Engine Interface drivers which was supposed to solve the problem. I installed that driver, the PCI Simple Communications Controller was then no longer listed in Device Manager. Sadly, neither is the ethernet LAN.
About to try Knoppix live CD.

Yes. Windows is up to date.

The machine has gone to Toshiba for warranty repair. I'll report the findings for posterity when I get it back.
Thanks for your contributions.

I've been in contact with Toshiba. This is a known issue.
They've given me conflicting advice but none of the 3 drivers they pointed me to worked.
:(
Thanks for the input. It may take me a while to finalise this.
