More information is needed.
On the PC that cannot connect, select Start, then Run. At the run command type 'cmd'. From the command prompt type 'ipconfig'.
What do you see? If the IP Address says 169.254.X.X (Xs could be anything), this indicates that you are not getting an address from the router. If it is 192.168.X.X, then this should be a non-issue.
If you want to check on a mac, you need to get to a command prompt(not sure how), and type 'ifconfig'. If it says 0.0.0.0, then you are not getting an address.
That fact that changing cables and ports has no effect makes me think the the router is not giving you guys addresses.
If this is all kosher, we can take a look at sercurity.
