Neither wired nor wireless working Windows 7

At the moment, i don't have much knowledge of the history of this problem but the symptoms are that neither wired ethernet nor wireless works* on this Asus X5DIJ laptop under Windows 7. Neither does it work under Ubuntu. Since there are no deactivations of networking possible in the bios (i don't think) and networking isn't disabled through function keys, i'm suspecting a hardware problem.

I wonder if that's a correct (very) general diagnosis or is there something else? If so, why would network hardware fail generally?

*'Not working' so far, means the following was noted

a. ui networking applets reported 'limited connectivity'
b. ipconfig shows an 'empty' tunneling entry
c. ifconfig (in Linux) reported having an ip address and i was able to ping other boxes on my lan, but not outside it (using an IP address)

run: ipconfig /flushdns
ipconfig /release
ipconfig /renew
ipconfig /registerdns
ipconfig /all what is the default gateway set to? Is it your router? Can you ping the router?

I'd start with the wired NIC just to eliminate some variables.  If it doesn't work under Win7 or under Ubuntu (or whatever other boot CD you might try), then it could be hardware

OK. Progress - eliminated HW by getting wired and wireless working in Ubuntu. Back with more later

I have seen a similar symptom on Windows XP and Vista and what I final result was, in both cases a virus took out the TCP/IP stack.

Well, i'm trying to start with the wired lan connection. When repair is attempted, i get something like 'Windows could not bind the adapter to the TCP/IP stack" so it looks like something like that might be afoot. It used to be possible to reinstall TCP/IP - i wonder if you can in Win 7 - might be worth a try
CEHJ,

This all sounds very  familiar.  I did a quick sereach and found the following...

How to reinstall the TCP/IP protocol driver on Windows 7?

Maybe worth a 'look-see'....

Hope this helps,

CEHJ,

Something I forgot to mention.  You could use the Windows 7 Repair CD to build the TCP/IP stack.

How to reset Internet Protocol (TCP/IP)
http://support.microsoft.com/kb/299357 

Yep - already tried it. It failed. And didn't even create the log file
I also ran their executable version of it just in case i'd made an error. No improvement

"Windows couldn't automatically bind the IP protocol stack to the network adapter"
You were running the netsh command from an administrative prompt, correct?  Was there an error message when you tried to reset the stack?

I would also run a system file check
sfc /scannow
If it corrects any issues, then go back and try the TCP/IP reset again.  Also, a winsock reset wouldn't hurt.
netsh winsock reset

Yes
Was there an error message when you tried to reset the stack?
No

I might try your other suggestions tomorrow. I've already wasted a lot of time on this. The error has only been solved in certain cases. It looks serious and i shall probably have to tell the client that the only way to fix it is to reinstall Windows if a restore fails
sounds like a virus to me its very common  these days

CEHJ,

Thank you for the points and the best of luck.

If you haven't wiped it yet, was Norton Internet Security or McAfee Protection recently uninstalled?   I just remembered a few years ago Norton disabling the physical adapters and installing its own psuedo adapters for their 'real time protection' scanning and when I uninstalled it, I had symptoms as you describe...

Thanks. It's conceivable that there was some AV source to the problem. It's now running AVG (some non-free version), but who knows, she could have tried some other AV app before. I've seen this documented in connection with Kaspersky too

Helpful comments guys, thanks. Restore/reinstall will be my recommendation
