FC8 newly installed, can not connect Internet
I have just installed a FC8 core on a newly built PC. everything was done as told, but I can not access internet. my computer is connected to a router with DHCP, and router is connect to the internet with PPPoE. other exisiting computers on the LAn can access the internet without problem, but not the FC8.
I have check the network setting, no matter what I do with automatically obtain IP address ot static IP address, none of them worked. DNS was Primary: 192.168.1.1, secondary: 192.168.1.1.
I also checked the help manual, and I was told to delete both DNS setting if my IP was obtained from DHCP services. but it is still not working.
Can anyone help? anything to do with MTU setting?
