Internet Connection Problem

Hi.

I just installed Windows 7 RC 7100. Everything was just working fine. One day, after I restarted the computer, it couldn't connect to the internet. I opened the Network and Sharing Center and there was two networks (Home and Public, when should be just Home). The internet works if I disable and enable again the network adapter.

This don't happen when I hibernate, just when I reboot.

I use Cable internet (Motorola SBV5121 modem) and a Marvel Yukon 88E8040 network adapter.

I already updated the adapter driver.

Does anyone has a clue of what's happening ?

Already tried. It didn't. Actually, worked once. But when I restarted, the problem came back.

i had a same problem,u should try this:go in network and sharing centar,then click on see full map,it will show u your network map,then put mouse pointer over the gateway,remember his ip,then go on yours Home network local connection,and click properties,then IPv4,then advance,and go to WINS,and add the ip from the gateway there,that help me with the same problem

Onestyle.

Thanks man. That worked.

Just one question, Will this gateway ever be the same? Or if i restart the modem, it will change?

i think so,and no it won't chane if u turn the modem off,but if you lose net again,just do the same thing,check again the gateway,if the gateway is the same,just do troubleshoot,if that didn do any help log off or restart your pc,and u will have net again....if u have any problem with win 7 contact me,and i'll help u,i'm a long time tester of this great os,and i had many problems,solved all hihi

I am having the same issue. I have updated my driver and enabling/disabling the adapter is the only thing that works. Some additional history:

I installed Win 7 and internet did not work, showed an error. Other local computers are able to access shared folders on the Win 7 machine so error was only going through gateway (no internet access). It is set to DHCP and IPV6 is off and using latest diver for REAL tek onboard NIC. Running ipconfig shows 0.0.0.0 as default gateway but in some instances shows the real default gateway (router IP) under the 0.0.0.0 so essentially showing 2 gateway addresses. Resetting the NIC seems to work for a few hours but eventually it gets a gateway error. I have also tried a usb nic (linksys) to see if maybe a new nic would solve issue but the usb nic experienced similar issues (although I did not fully test it). Other PC's running vista or xp work perfectly fine connected to the router. Swapped cables and ports so it seems that this is a Win 7 issue.

Any thoughts on things I can try?

you got a error like --turn off your modem,wait 10 sec--something like that,in that case do the same thing that i wrote above,and restart the pc when u r done,u should have internet then,

I have tried the reboot methods but still fails after a few hours.

have u did like i said in my first post,the all gateway procedure....that should help,and enable ipV6 a dhcp and in ip-v4 as default gateway add the same thing like in wins ...and after that apply and restart...and something else 0.0.0.0.0 cant be your gateway
