Just in case, make sure you restart your wireless router and your modem because you’ll waste a lot of time messing with your computer for no reason if it’s actually a problem with the router.
You can try to reset your network settings and fix any problems with the TCP/IP stack by running the Microsoft FixIt solution here:
If nothing else has worked so far, try upgrading the firmware on your router. This is a slightly more technical process because you have to connect to your router via a web browser, but a little searching on Google will give you step by step directions. It’s a fairly easy process and might solve your problem, especially if you have an older router or have had one for a long time and have never updated the firmware.
If you have both an Ethernet connection enabled and a wireless connection on your laptop or desktop, that could be the cause of the problem. You can either try disconnecting one, restarting and then seeing if you can get Internet access for each individually or you can try to bridge the connections.
You can do this by going to Network and Sharing Center, click on Change Adapter Settings, then select both the Local Area Connection and the Wireless Network Connection and right-click on either one. You will see the option to Bridge Connections.
Doing this can fix the problem of both networks conflicting with each other. Give it a shot if nothing else has worked until now. You can always unbridge the connections later on if you like.
This solution is a little trick because it can be something random, but you need to go to Network and Sharing Center, click on Change Adapter Settings, then right-click on Local Area Connection or Wireless Network Connection and choose Properties.
You’ll see a box that says This connection uses the following items, which contains a list of protocols used by the network card to communicate. It should look something like this:
Now if you installed some network related software like VPN software or something like that, you might have some strange extra stuff listed in there. You need to uninstall those items and basically have something that looks like the list above. Once those are removed, restart and see it that solves your problem.
If you have VMWare or any other virtual machine software installed, go to Device Manager and disable any virtual network adapters that may appear there under Network Controllers. You won’t be able to connect to the Internet from your virtual machine, but you can always re–enable them for that. If the problem goes away though, it might be worth upgrading to the latest version of the virtual machine software to see if it’s more compatible with Windows 7.
You can go to Network and Sharing Center, click on Change Adapter Settings and then right-click on the network adapter and choose Disable. Wait a little while and then re-enable the network connection.
That’s all the solutions I could find for fixing this problem. If you still have unidentified network with no Internet access, then post your specs here and we’ll try to help! Enjoy!
