Windows 7: Unidentifiable Network LAN

Hello and thank you,

So it all started when i updated my bios, i then had the issue of unidentifiable network. Then i tried to do a clean install of Windows. Didn't help. I then connected the usb wireless adapter we have and had no problem. Then some how the network got connected and my LAN had the name of the wireless but worked. Then i was being retarded and tried to update the driver and it got messed up again. We got a new router from att so i know its not the router. When i go on the router page it shows my pc connected fine and when i go into details of the connection on my comp it shows all the correct information (ie. IP, default gateway, ect.). So i don't know what to do. Please help me figure this bugger out.



Thanks a million,
Forrest

Hi Forrest,

I would suggest you to try the below mentioned steps one by one.


STEP 1:Update the network driver.
Steps to update network driver:
1. Click on start button.
2. in the search box type “devmgmt.msc” and then press enter.
3. Select the network card device and right click on it
4. Now select properties.
5. In the properties window, under “Driver tab”, click on “Update Driver button”.
6. After installing the updates restart the computer.

STEP 2:Try resetting the TCP/IP stack.
To reset the TCP/IP stack go to this article and either click on "Fix it for me" or follow the instructions to fix it yourself:http://support.microsoft.com/kb/299357

If still the same problem persists then try the next method.

STEP 3: You need to troubleshootusing the Network troubleshooter inWindows 7and check for the issue. To do that click the below mentioned link:

Kindly let me know for further clarifications.

Hi Debbie,
thank you for the suggestions however they did not solve the issue. When I ran the troubleshooter it tells me that the default gateway is unavailable. This does not make any sense because the default gateway has not changed and I also had run the trouble shooter on the old router and it said the same thing.

hi forest man, you have to go to network setting and then change ip address setting to automatic detect

Thank you for the advice however I have tried this and made sure it is automatic and it still does not solve the issue.

If you can ping the lan side of the router and a real world IP then there isn't any real problem other than the connection being reported as Unidentifiable. You haven't stated that your internet works or not. Im just assuming it does as you have a IP/gateway.

If it was brought about by a Bios flash to your PC, then perhaps the easiest option is to reflash to the previous version of Bios. Was the new bios a beta? Have you checked for an updated NIC driver for that version of BIOS? If a network driver update doesn't fix it I would be reflashing to the previous or other known good version of Bios.

Unrelated but similar, I tried some of those D-Link 500 EoP devices and like your issue, Windows 7 said it was an unidentified network as well. No driver update was required, it just worked.

Did the problem exist before the new router or after? Does the new router have a newer BIOS available?

Just to clarify no i cannot access the internet over this connection and my bios is not beta. The unfortunate thing is that i cannot roll back the bios because the built in flash tool tells me that it is out of date and cannot be used. I have updated and backdated the NIC driver. Nothing seems to be working. And yes the problem existed with the old router. The connection i feel is not the problem because i tried the same ethernet connection in a different comp which gained internet access no problem.

here is the details of the networks. one the local connection that has the issue and the other is the wireless network connection through the usb wireless adapter connected for me to access the internet.

After you update the bios it is sometimes required that you go into the bios and set the bios back to default settings and reboot the machine. After that, Restart and go into the bios to make sure all settings are correct.

You may also need to clear the cmos and start over again from scratch. This should get your network interface to work again.

Unfortunately neither of these things solved the problem any other suggestions? Thank you again everyone.
