Windows 7: Unidentified Network - No Internet Access


07 Jan 2010   #1

Windows 7
 
 
Unidentified Network - No Internet Access

I've read multiple posts about this problem but no concrete solutions. My problem is a bit different than the usual usecase.

Win 7 64 bit
Asus p5k se (integrated NIC)

Everything was working fine (a couple of months) until today. The only thing I did was trying to install some extra memory into my machine. That failed (but is a subject for another post). Problem started happening after that, but I find it hard to believe that it the two things have a direct connection.

In my case, the NIC manages to get an ip from the router (this is a direct cable connection, not wireless) and the gateway address is correct. However I still get the Unidentified Network - No Internet Access error. I'll clarify that the IP and gateway info appears on the Details screen of the network adapter. The main status screen shows (among other things):

IP4 connectivity : No Internet Access


I cannot ping my router. It's as if the negotiation phase between the computer and the router goes fine and then nothing. Looking at the DHCP table in my router I can see that my machine appearing there with a 192.168.1.2 IP.

I tried all the usual solutions:

Uninstall driver and reinstall
no DHCP
turn off computer
power off and take out cable
disable and enable adapter

I also saw that some software named bonjoure is blamed for a similar problem but I don't have that installed.

Any ideas are more than welcomed.

Have you tried clearing the cmos? That will usually get that NIC back in these types of cases.

Do you mean taking out the battery? I haven't yet. Anyway, it is not that the NIC is not there it's just that windows 7 seems to have some problems with it. Any ideas how to test it in order to rule out a hardware problem?

believe it or not the failed RAM install could be the reason your onboard nic is having it's issues, lol. reset CMOS battery like chev said.

There is a button or a three pin connector with a plastic change over on your board for this. You can look up the procedure but it's mostly common sense. It's really easy to find pictures of this procedure and you can also look up the exact location of the cmos button on your board fairly easily.

Removing the battery will also work but no matter how you do it you will need to reset the bios time and other important settings must be returned to how they were.

I'v seen this fix your type of problem on many occasion.

I reset the cmos but the problem is still there.

BTW today was the second day I tried to install the extra ram. I had no problem trying yesterday (as in installing ram didn't cause this weired NIC behavior)

In that case why not attempt to reinstall the NIC drivers if you have them handy. You can also try going into Device Manager and update the drivers or roll back and see if that changes anything. If that doesn't work you can also try using a PCI-e NIC card in case your onboard died or something.

have you reset the router by chance? Maybe it is where your internet problem is. If you have a second computer and that is working fine, then we know that portion of the connection is working.
