System Preferences>Network, click on the little gear at the bottom next to the + & - icons, (unlock lock first if locked), choose Set Service Order.

The interface that connects to the Internet should be dragged to the top of the list.

If using Wifi/Airport...

Instead of joining your Network from the list, click the WiFi icon at the top, and click join other network. Fill in everything as needed.

For 10.5/10.6/10.7/10.8, System Preferences>Network, unlock the lock if need be, highlight the Interface you use to connect to Internet, click on the advanced button, click on the DNS tab, click on the little plus icon, then add these numbers...

Can you connect to another wireless router?

As more and more people upgrade or add routers in your neighborhood, you may run into collisions. So first try to change the router broadcast channel and frequency for Wireless-N routers. Reboot the router and reconnect.

Alternatively, try plugging directly into the back of the router with an ethernet cable. This may help to pinpoint if the router isdefective.

If that doesn't work, then see if replacing your router resolves the problem. Maybe a bad router.

Good luck...

Thanks for the report! 🙂
