Windows 7: Default Gateway Not Available

It just happened about 5 minutes ago, and I took pictures this time so you know what happens, exactly.

The first image is when the gateway goes down. I click on the caution icon to bring up a 'troubleshooter' that scans and fixes the issue. #2 is the window that comes up after the repair. The last image is just my device info from that previous window.

The ipconfig /all looks completely normal. Which router are we talking about here? It would be useful to know the brand make and model number of this router.

You can sometimes get around default gateway problems by typing in the default gateway into your IPv4 properties manually. This would only make up for a router problem of some sort but it might be worth a try. There may be other options we can pursue once I know what router this is.

The router I have is a Trendnet TW100-S4W1CA.

For the IPv4 properties, do I add the default gateway into both the IP address and DNS server address?


I like to think I have a shred of a clue about computers until I have problems with them. Then I feel a bit clueless. Or a lot.

Right now I have my router removed from my network, and I'm downloading large files to see what issues may arise.

It just happened with my router completely removed from the network. Just when I thought I couldn't become any more confused...

Same steps as above to repair.

Didn't happen yesterday, not sure if it's fixed, the day is still young!

Things I tried: Disabling flow control and disabling the 1 service I had running other than MS services.

Hope it's fixed, will post back if it's still causing issues.

Any more suggestions?

Do you have anything from Apple installed like itunes or do you have Adobe photo suite installed on this system?

No, I have neither of those programs installed.


I do have Adobe AIR, Acrobat Reader, and Flash Player installed.

I don't even have Quicktime installed on this computer for Apple programs, as I had in XP.

It seems like your TCP/ip stack is messed up or maybe winsock is having a problem.
Try running this batch file which will reset winsock, reset the TCP/IP stack and release renew your IP. Reboot after you run the batch file then repost your ipconfig /all here please. :)

Default Gateway not doing anything
I am using a router with internet access with the default gateway of 192.168.1.1 and another router with intranet access with the default gateway of 192.168.105.4 and the internet router is not being accessed even with the correct address. It thinks those two are the same.
