Windows 7: Unidentified Network/Internet access

Unidentified Network/Internet access

Did a forum search and could not find my particular problem.

I have a small business network (15) running through a Linksys RVS4000 router with DHCP enabled.

One workstation will connect out to the internet upon reboot or disabling/enabling the NIC, but shortly thereafter disconnects. It does, however, maintain seeing all the workgroup PC's and accessing mapped drives. The IP address and gateway are obviously legit when checked.

I have tried most all of the suggestions in other threads with similar issues (ipconfig release/renew, dnsflush, system restore), including restarting cable modem and router, but the darn thing keeps flipping to unknown network and cutting off internet access.

Any suggestions? Thanks.

Well, I've tried everything I can think of from suggestions on this board and others, including system restore, reinstalling the NIC, removing firewall and all security (Microsoft Security) moving to another location, windsock reset, ip reset.....still cuts off after ~5 minutes. (I've left some things off I'm sure)

Any help would be appreciated. Thanks.

I would need to see a screen shot of the ipconfig/all form this machine in order to help you.

Have you attempted to update the firmware on the router?

No, all other machines on the network have full access and this specific machine still has access to all network drives. I have restarted the router and modem and all network PC's.

Thanks.

Thanks!
No problems visible here. But I'm sure this is when the connection is working.

Have you tried to start up in safe mode with networking to determine if an installed program or A/V software is causing the problem?

If the problem goes away in safe mode then most likely the problem is caused by something installed on the system.

Have you been to the Windows Update Center recently?

Have you tried to update the Intel driver from the Intel site directly?

Of course updating the Intel driver is the easiest option here, there appears to be a new driver 1-11-13 for your Intel adaptor. Choose the correct Op system when you get there.

Actually that screen shot was when it was not working.

Yes, I did check it out in safe-mode. Same issues.

If I renew the IP address it will work for a few minutes and click off.

Thanks.

Please update the driver from the Intel site. I added that link to my last post.

Is there anything from Apple installed on this system like iTunes?

Driver updated....

There is no iTunes on the PC in question.

Thanks.

edit: Driver update did not solve.
