How to Log In at 192.168.11.1

1
Connect to your router's network

Connect your device via Wi-Fi or Ethernet cable. You must be on the local network - mobile data or other networks will not work.

2
Open a browser and type http://192.168.11.1

Type the address with http:// explicitly. Modern browsers default to HTTPS, which will fail on a router without an SSL certificate.

Troubleshooting

1
Accidentally typed 192.168.1.1 and got nothing

Buffalo uses 192.168.11.1, not 192.168.1.1. Type http://192.168.11.1 exactly.

2
admin / password not working

Check whether the password was previously changed. Press and hold the router Reset button for 3-5 seconds to restore factory defaults including admin/password.

3
Want to install DD-WRT on a non-DD-WRT Buffalo model

Buffalo AirStation admin panel supports DD-WRT flashing via Administration → Firmware Update on compatible models. Check dd-wrt.com router database first.

FAQ

Why does Buffalo use 192.168.11.1 instead of 192.168.1.1?

Buffalo chose 192.168.11.1 to avoid the IP conflict that occurs when customers add a Buffalo router behind an existing ISP-provided router at 192.168.1.1. With different default subnets, both devices are accessible on the same network without reconfiguration.
