My problem is that my Local Area Network adaptor is showing Unidentified Network.
I am running a Win7 computer with the latest updates (20/12/2012) on a Dell Optiplex 740 with onboard LAN. It is Ethernetted to my Wireless ADSL router.
I have several other computers using wireless off the same Wireless Router with no problems.
I have tried:
1. Uninstalling the LAN adaptor and its drivers, and also updated the drivers.
2. Adding and removing protocols associated with the adaptor, of which all have been re-added as before.
3. Restarting the Bonjour service.
I have just installed a USB wireless dongle and it says this is also an unidentified network!
Most likely it is still the Bonjour service, you can't kill the responder even in the task manager. I would delete the Bonjour service for now (you can reinstall it later if needed). In the run box window type: %PROGRAMFILES%\Bonjour\mDNSResponder.exe -remove and then regsvr32 /u %PROGRAMFILES%\Bonjour\mdnsNSP.dll
Thanks for your help so far.
I've uninstalled Bonjour successfully. I'm now sure its not Bonjour.
I've also tried:
1. Route Delete 0.0.0.0
2. Uninstalling the LAN device and reinstalling
3. Updating the drivers to the LAN device and firmware to the Netgear ADSL router.
4. Resetting TCP Stack
5. I can't release or renew IP because its not getting an IP in the first place, just autoconfiguration IP's and loopbacks.
6. Typed Unidentified Network into google and tried the first 15 results and all the attempts at a fix in each one and ALL failed.
And I assume that you have no services running that can block access, like McAfee.
Also, just for completeness, try going into your network control panel and change your network type from Home to one of the others and then change it back. For some odd reason that sometimes can fix the network. This assumes that you have an icon under active networks that you can click, even if it is unidentified. Is there only one icon or multiple, such as Home and Unidentified Network?
I had this issue "Unidentified Network" but it was setting up a new router, a TP-LINK TL-WR702N. I was trying to log into the new router and setup a name and password for it by going to 192.168.0.254 in IE running Windows 7. IE would say there was no connection and in the Network and Sharing center the wireless network had "Unidentified Network" and I could not change it.
I found out that this TP-LINK router has DHCP turned off by default.
To fix this you need to:
1. Go into the Properties of the wireless card.
2. Double click on Internet Protocol Version 4 (TCP/IP4), and manually assign the IP address to 192.168.0.120, so it is from the same segment.
3. In IE go to setup on the router by accessing to 192.168.0.254 and logging in with the Username and Password from TP-LINK.
4. Click on DHCP on the left hand menu and turn it ON.
5. Click Save and Reboot.
Once that was done the "Unidentified Network" went away and I could pick the type of network for this router. I could then go back to Internet Protocol Version 4 (TCP/IP4) and set it to Obtain an IP Automatically.
