Windows 7: Unidentified Network, Windows 7

Unidentified Network, Windows 7

I recently moved into a new place and I have a switch connected to the ethernet port of my wireless router. From that switch I have 3 computers running, all Windows 7 x64. Both of my laptops can access the network, however my desktop is unable to connect.

I've tried dozens of solutions to no avail, upon browsing for hours. Attached is my ipconfig -all log, if anyone could help me out I would appreciate that a lot.

It looks like you aren't getting anything from the router, no default gateway or IP nothing valid there at all.

Have you tried resetting your router yet? Have you tried to update the routers firmware?
Run these commands at your command prompt and see if anything changes.
netsh winsock reset catalog (reset winsock entries)
netsh int ip reset reset.log hit (reset TCP/IP stack)

Then ipconfig /release then ipconfig /renew

Hi chev65, appreciate the quick response.

I have tried resetting the router (multiple times). The firmware should not be an issue if my other 2 computers (1 Windows 7 x64, 2nd W7 x86) are able to connect (the last computer that is unable to connect is also W7 x64) through the same switch. However I will try that right now.

Just tried your above commands and first 2 commands worked. Release and renew didn't work, @ release: "An error has occurred while releasing interface Local Area Connection : An address has not yet been associated with the network endpoint."

When I renew, "An error has occurred while renewing interface LAN : unable to connect your DHCP server. Request has timed out."

Again, I greatly appreciate your assistance.

It probably didn't release because there was no valid DNS servers on the list.

Do you have any manual entries at your IPv4 properties window?

It looks like something is blocking the machine from picking up DHCP from the router, maybe an A/V software or third party firewall?

Not that I'm aware of... I've hard reset the router multiple times, and if my other W7 machines can get online that theory doesn't make much sense. Disabled Windows Firewall (only firewall on) and still not working.

If you can list your system specs it might help to look around for some more recent drivers for this system.

If you can find a more recent firmware for your router I would install it, the fact that this router works with other win7 machines doesn't mean much because they are all using different drivers and some work better than others with certain firmware.

There are more problems then just the default gateway, the DNS isn't correct, the IP isn't there, and the subnet mask is all wrong. Although it can sometimes help to enter the correct default gateway manually into the IPv4 properties window.

The problem is that I don't even know what default gateway the router is supposed to be using. So I would need to know the routers make model to figure that out.

What ever the default gateway is it would need to be entered manually where it says default gateway replacing 192.168.1.1 with the correct one.

We can get also this info from one of the other machines ipconfig /all, though it might not be enough to fix the problem.

I am using a Linksys WRT54G router; the default IP is 192.168.1.1.

That particular router has lots of complaints, sometimes it works with Windows 7 other times not so well. Seems to depend on the firmware updates. There are about a dozen versions of that same router. Thinking that well if it works with one machine it should work with another doesn't fly because of compatiblity with certain drivers.

I would go with either the tomato firmware or the DDwrt firmware, but linksys may have a firmware that works also. You can find them by googling around a bit. You need to use firmware that is made for your routers version number so it's important you get the version number first. I've seen lots of problems fixed with this router by updating the firmware.
