Internet sharing problems

[GrayFox]

Hi all. First post

I'm having some problems with my internet sharing. When i reboot my pc (the one that's connected to the modem), i have to go to the network connections to remove and set the internet sharing. I had internet sharing for a couple of years now, didn't have any problem till this last format.

It's not a driver problem, cause the PCI nic is always automatically installed by windows, and the onboard gets the cd drivers (P4C800 mobo). I updated the onboard card drivers when i started having this problem.

any thoughts on this??

Thanks in advance
