Network connection problems on Win 7 Laptop

I have a problem with Acer Aspire 4810TZ laptop (Win7 Pro, 64-bit).  After installing Cisco VPN client, I could not connect to ANY network (LAN, wireless).  Now, I've uninstalled Cisco, even run system restore, but still can't connect to network.  On all available wireless it says "limited access", and on LAN it's just not connected (however, lights on the NIC are ON).  Any suggestions?

Are you running Symantec End Point Protection per chance?

Try the following:

Open a CMD prompt as Administrator (Start | All Programs | Accessories).  Right-click Command Prompt and choose Run as Administrator.
Type in:

netsh int ip reset

Restart your computer.

Have you checked to make sure TCP/IPv4 is DHCP enabled and that the DNS section is also set to automatic?  Sounds DNS related.

There is no VPN mini-port drivers.  TCP/IPv4 looks fine - DHCP enabled and DNS automatic.  When I'm trying to use Windows Network Diagnostics it says: Problem found.  There might be a problem with the driver for the Local Area Connection adapter.  I downladed latest driver from Acer, installed it, but it did not solver the problem.

In addition to my previous comment in the issues found it says: "Windows couldn't automaticaly bind the IP protocol stack to the network adapter."

Boot to safe mode, remove the drive and any other drivers under you NIC and reboot.  Let windows find it again and point to the newest drivers you downloaded.

Ahhh, uninstall TCP/IP and re-install it.

Thank you, airborne.  I thinh the issue is solved.  There was the GreenBow NDIS filter driver in both network adapters used items.  At the moment I uncheck it, it found the network.  Thanks again.
