I'm setting up a new D-Link N300 router, and trying to connect a MacBook Pro and a MacBook, both running OS X 10.6.
As the question says, either computer can connect to the internet when connected to the router via Ethernet. And either one can get on the router's wireless network. But when connected wirelessly (without the Ethernet cable plugged in), neither one can get online.
I can't figure out why that would be. Any help appreciated.
