Windows 7: "Unidentified Network" revert to factory settings did not fix.

"Unidentified Network" revert to factory settings did not fix.

I am back home for the holidays and brought my desktop back with me that runs Windows 7. After I got it all set up I realized I could not access the internet, and that I was connected to an "Unidentified Network". After looking into it more I found that I was getting a 169.XXX.XX.XX IP, and I was unable to renew it. After searching the internet for a while I found many people with similar problems and tried many things that were suggested such as

"Clean Boot", by making sure that Norton and Bonjour, which apparently can cause these problems, were disabled at startup
Updating the Drivers on my network adapter
Reinstall the network adapter
Reset the router and modem
switched out ethernet cables
Set my own IP
Tried to do a system restore (whole restore failed, tried to update then lost all my past restore points)
Tried starting in safe mode and safe mode with networking, neither worked.
and finally restoring my computer to factory settings (Windows Vista), which I thought would fix it but did not, leaving me with very little hope.

Nothing really changed between it working and not working, and all the other computers on the network still work.

I have what I consider slightly above average understanding on the software side of things, and limited when it comes to hardware. So I'll probably need an explanation of what to do. This computer is barely two years old.

HELP!

Given that you moved it, it may be as simple as re-seating your wifi card.

I should clarify I'm connected via ethernet cable, not wi-fi.

System specs might help, so we know what hardare we are dealing with. My crystal ball is in for repairs.

If you are using a Ethernet "card" same thing may be true.

169.254.x.x is a local address to the hardware. It means it isnt configured correctly to obtain an IP from the DHCP/DNS server.

Can you run IPCONFIG /all from search and upload the output?

You took a desktop on holidays with you??

Anyways as zigzag said this 169.254.xx.xx address
is an APIPA (Automatic Private IP Address) which is assigned
by Windows when a server cannot be reached.

You need to make sure that "Obtain IP address Automatically" is
selected and "Obtain DNS server address automatically" are checked
and then try to renew your IP. This is because a static IP address is not
able to be renewed and therefore, you setting the IP address is like setting
a static IP.

If that doesn't help then you may possibly have corruption of the
tcp/ip stack (winsock) due to malware/virus, update of networking software
or a security program deleting a neccessary file which may have been corrupted
and then cleaned during scanning.

To reset winsock- type the following at command prompt:
netsh winsock reset catalog (which will reset the winsock catalog entries)
netsh int ip reset reset.log hit (to reset/ rebuild the stack)

Try this after trying to renew the IP address with the appropriate settings
being:
ipconfig /release
ipconfig /renew

Failing that it could well be a hardware issue due to the movement associated
with the trip. To test the network card simply try to connect to another network
to eliminate hardware failure as a possible cause

Good luck

Yah, when I ran ipconfig /renew i'd get an error saying DHCP server couldn't be reached which would make sense. Anyways here it is. And this would be post factory reset so this it's Vista.

Fair enough

Listen mate, do yourself a favour while you wait for me to go over those last couple
of posts and edit your MAC address out so you don't have a million people trying to
look at your gear when you do get connected.

Just my humble opinion but you should not post that info.

I have to leave very shortly however I have sent a private message to zigzag
asking to help on your behalf now that you have posted your ipconfig results.

Just one thing before I go - check the settings of the 2 working machines
and look to see if they have IPv6 settings as well. Your device
may not be capable of handling IPv4 AND ipV6 at the same time and I
notice that you have them both set as preferred options. What I am saying here is, try
disabling IPv6 to see if that makes a difference.
(Can IPv4 AND v6 be on at the same time??) - Hmm - Calling Dr. Google


Good luck- I hope you get this sorted and are back in action ASAP.
