unable to connect to internet- default gateway IP 0.0.0.0

vamsik · 23 Feb 2014

Hi all,
I am connected to wired modem directly to my Dell studio (windows 7 home premium 64 bit) laptop. I am using this connection for past 6 months and it's working fine. all of sudden from yesterday I am not able to connect to internet. I am getting yellow Warning symbol on the network sharing icon in task bar.
When I connect the same connection to my friends laptop, are bale to connect to internet.
I ran diagnostics and it's not able to run "local network communication test".
Error Reason : the default gateway is populated with 0.0.0.0
I had checked in cmd prompt for my adapter settings. there also Default gateway is empty.

I had tried Following things
1.DHCP is enabled
2.Turned off my AV(microsoft essentials)
3.reset WINSOCK, IPv4 TCP/IP, and IPv6 TCP/IP stack.rnet
4.Unistalled &installed the driver(n/w adapter : Realtek RTL8168D/8111D Family PCI-E gigbit Ethernet NIC (NDIS 6.20))
5. n/w trouble shoot report says "local area connection" doesn't have a valid IP configuration

Nothing worked. What doesn't make sense is till yesterday everything is working fine and I didn't make any changes on my system.

Can some one tell how to fix this issue?

The fact of the matter is that your two different VMware virtual adaptors are the source of the problem.

These virtual adaptors cause connection problems all the time, having two of them active is a problem here. People don't realize that things like Hamachi or VMware can create connection problems and do so on a daily basis.

You will need to remove them completely by disabling or uninstalling them, after that test for connectivity on your usual connection.

You might try reinstalling the VMware after you reestablish your connection.

The network stack may be corrupted at this point so it's best to unzip and run the file below which will reset the network stack. Your machine will reboot automatically when it's complete.

If this connection is only with a modem and not a router then it may be required to reset the modem in order to rebind the ISP/modem with your MAC address.

Please post the ipconfig/all again after running the IPReset file.

Well that pretty much eliminates the problem coming from the machine. It looks like Windows is seeing the modem/router because of the 169. IP but it doesn't seem to be picking anything up from it.

I'd have to go after the router/modem at this point, although this is usually a first step with these types of problems. Have you tried resetting the modem by unplugging it for a few minutes then try to reconnect?

It makes no difference if one machine can connect to the modem/router while the other one can't, this type of logic does not work with routers or modems, you still need to reset the modem.
