Basic Router Troubleshooting from a Mac

If your router is not behaving normally, begin by using the resetting all settings. With the unit connected to power, hold
down the reset button for 3 seconds. This will reset all settings to their defaults. The local IP address of the router will
now be 192.168.11.1 with a 255.255.255.0 subnet mask.
Connect your Mac to one of the Ethernet ports on the router. In System Preferences - Network - Ethernet, give the
computer a manual (fixed) IP address on the same subnet as the router such as 192.168.11.2. Set the subnet mask to
255.255.255.0.
If your Mac doesn't have an Ethernet port, connect it to the AirStation wirelessly instead. The AirStation's default SSID
and passphrase are printed on the setup card in the bottom of the router. Use this information to connect wirelessly.
Then, give the computer a fixed IP address on the same subnet as the router such as 192.168.11.2 and set the subnet
mask to 255.255.255.0.
Open a browser (such as Safari) on your computer and type 192.168.11.1 into the URL window. Click Go. The router's
settings page should open.
Enter the router's username and password ("admin" and "password" by default).
You should now be able to reconfigure your settings and change your password for the router.
