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)

ipconfig /all what is the default gateway set to? Is it your router? Can you ping the router?

Hello CEHJ,

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.  I was able to isolate this by using Windows Safe Mode and the use of USB Wireless Adapter (I think I used the Tenda USB Wireless which cost about $10.00).  

By introducing a completely different wireless solution, you can isolate the 'embedded wireless' logic and move on from there.  In the case of the Tenda, it comes with it's own Wireless Configuration app which is pretty simple and works very good.

To see if there is a Virus causing your woes, may I suggest going to CNET and downloading the following AVs:
  1. Malwarebytes
  2. Spybot
  3. Superantispyware
  4. Avast/AVG or Panda, which ever you wish.

I would suggest downloading these modules from another system, use the CNET website, use Firefox (My personal preference), and place them on  a USB Memory Stick.

You can install AVs 1, 2 and 3 in Windows Safe Mode, but Avast will not install, not sure about the others as I do not use them.  Install the AVs, Update them, and you can run all three (AVs 1,2,3) at the same time... it generally takes about 2-3 hours complete all three.

If you have a lot of viruses, then reboot, go into Safe Mode and run them again... until you see no more viruses or malware (Cookies, Adware and such).

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, or you could be using bad addresses for your IP settings.  Double check the IP, subnet, gateway, and DNS.  If you're able to ping internal IPs, then your IP and subnet should be fine.  If you can ping external IPs then your default gateway is fine.  Last try pinging (or use nslookup) external FQDNs.

Also, double check the hardware.  Are there LEDs that light up when you plug a network cable into your NIC?  Have you tried a different cable?  Different port on the switch or different switch?

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

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...

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.

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

Well Malwarebytes gives it a clean bill of health, at least on a quick scan, although the db is 47 days out of date (idiotic), despite the fact i just used the download link they supplied

I suspect if there is any Malware, it probably goes by the name of Windows 7

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
