Since windows 7 install, interent wont automatically connect

[Gadge]

After installing windows 7 i now have to connect to the internet by going into device manager and disabling the network realtek LAN adaptor and then re-enable it.

The yellow triangle then goes from the taskbar network icon and I'm now on the interent.

Anyone know a reason for this?

I do a search for the specific driver later, either from realtek its self or gigabyte (mb).
