Windows 7: Internet connection limited after installing new wireless adapter

Internet connection limited after installing new wireless adapter

I installed a new wireless adapter yesterday in the hope of increasing my internet speed. After installing the driver for the adapter I realised that my internet was no longer working. I can still see the connection but it is limited and doesnt allow me to connect to the internet. I also had a system up date the night before and hadn't been on the internet since that happened so am unsure if this has any part in it.

I have tried uninstalling and reinstalling the drivers for both the adapters i have to no avail, as well as plugging my pc into a laptop and using internet connection sharing which also doesnt work.

If i run a network repair i end up with two problems found:
1)There might be a problem with the driver for the local area connection adapter
2)There might be a problem with the driver for the wireless network connection adapter
They both have yellow signs with exclamation marks next to them.

If i type ipconfig/all into the cmd line I get:

Windows IP Configuration

Primary Dns Suffix . . . . . . . :
Node Type . . . . . . . . . . . . : Mixed
IP Routing Enabled. . . . . . . . : No

Shouldn't my wireless adapters appear here?
This problem is really starting to annoy me so any help would be fantastic.

Welcome to Windows Seven Forums.

Both adapters are wanting drivers - hence the warning signs in device manager.

What would help is if you gave us your system specs so that we can give advice on where to get the drivers.

Even computer manufacturer and adapter manufacturer would be a start, but at present we're in the dark.

BOOM just fixed it. In Network Connections I right clicked my wireless connection and went into properties. Then by unticking the box "AVG network filter driver" my internet started up all of a sudden
