192.168.11.1 Router Login
192.168.11.1 is Buffalo’s address, used across the AirStation range and very little else.
Which routers answer on 192.168.11.1
Buffalo has used this address consistently across AirStation routers and access points for many years. Because almost nobody else uses it, finding it on your network is a reliable indication that the device is a Buffalo unit.
Buffalo hardware is also unusually common as a base for third-party firmware such as DD-WRT and OpenWrt. If the panel you reach looks nothing like the manufacturer screenshots online, the router has probably been reflashed at some point, and the credentials will be whoever set it up rather than the factory pair.
Signing in
- 01
Connect to the router first
Join its Wi-Fi or plug into a LAN port. A private address is unreachable from mobile data or from any other network, so this step is not optional.
- 02
Open the address properly
Type
http://192.168.11.1in the address bar rather than the search box. - 03
Accept the certificate warning
Routers rarely carry a trusted TLS certificate. On your own hardware the warning is expected; choose Advanced then Proceed.
- 04
Sign in and change the password
Check the sticker on the unit first — it overrides any published list. Then replace the factory admin password before you do anything else.

192.168.11.1 not opening?
In access-point or bridge mode Buffalo units surrender this address and take one from the upstream router. Look for the device in your main router client list to find where it went.
The fastest way to settle it is to read the gateway address off the device in your hand rather than working down a list. On Windows run ipconfig and read Default Gateway; on macOS open System Settings › Network › Details › TCP/IP and read Router.
