The ROUTER / AP switch
Many AirStations have a mode switch on the back. In ROUTER mode the router is at 192.168.11.1. In AP mode, or in AUTO mode when it detects another router, it works as an access point and gets its address from your main router, so 192.168.11.1 no longer answers. Switch to ROUTER, or find the AirStation in the main router’s device list.
Problems typical for 192.168.11.1
- The page does not open in AP mode. See the switch section above.
- The interface is in Japanese. Models sold in Japan default to Japanese; look for the language selector at the top of the page.
- Not a Buffalo router? Check your default gateway first.
