This is weird, the 3G modem (Huweii?) should work independent to your LAN and Wireless adapter.

 

[zai87]

it's a Huawei 3G modem which is Mobile Broadband service. I got no idea regarding this problem. the internet access was just gone once i pluged the Ethernet to my DLINK router. do you have any suggestions?

I had the same problem

The problem you have had I to had and solved it by uninstalling AVG on my system. AVG was creating a secondary network with default gateway just like your system. My system would tell me at the command prompt when I had typed ipconfig that I had two default gateways one was 0.0.0.0 and the other was my router default gateway. the 0.0.0.0 was first in the list and all requests were going there instead of my default gateway for my router. AVG for some reason created this gateway 0.0.0.0 and I can only assume its for security reasons. Hope this helps someone, after removal of AVG I now have access to everything as I should have. AVG sucks
