Buffalo AirStation Router Login and Setup Guide
Buffalo routers use the unusual address 192.168.11.1 as the default gateway, not 192.168.1.1. Default login: admin / password. Some Buffalo models ship with DD-WRT pre-installed.
About Buffalo AirStation
Buffalo Technology is a Japanese manufacturer known for its AirStation Wi-Fi routers and LinkStation/TeraStation NAS devices. Their routers are popular in Japan, parts of Asia, and among enthusiasts globally for one distinctive reason: certain Buffalo models ship with DD-WRT firmware pre-installed, giving power users full open-source router capabilities out of the box.
Buffalo uses 192.168.11.1 as the default gateway - notable because it differs from the 192.168.1.1 or 192.168.0.1 used by most other brands. This deliberate choice avoids address conflicts when connecting a Buffalo router behind another router.

How to Log In
Connect via Wi-Fi (SSID on device label) or Ethernet.
Buffalo uses 192.168.11.1 as the default. Type http://192.168.11.1 in a browser. 192.168.1.1 will not work on a factory-default Buffalo router.
Username: admin. Password: password. On DD-WRT pre-installed models, the first boot redirects you to set a new password before the panel opens.

Troubleshooting
Buffalo uses 192.168.11.1, not 192.168.1.1. Correct address: http://192.168.11.1.
Press and hold the Reset button for 3-5 seconds. This restores the admin/password factory default.
Hold Reset during power-on for TFTP recovery mode. Connect to LAN port 1 and push firmware via TFTP to 192.168.11.1.

FAQ
Can I install DD-WRT on a Buffalo router that did not come with it?
Yes, on many models. Buffalo's AirStation firmware allows DD-WRT flashing via the admin panel on supported hardware - typically under Administration → Firmware Update. Upload the DD-WRT factory image for your specific model. Check the DD-WRT router database (dd-wrt.com) before purchasing if DD-WRT support is important to you, as not every Buffalo model has a verified working build.
Why It's 192.168.11.1, Not .1.1
Buffalo (Melco, out of Nagoya) is a Japanese brand, and in Japan the home router very commonly hangs behind an ISP fibre box that already claims 192.168.1.1. Parking the AirStation on 192.168.11.1 meant the two never argued over the address, no conflict, no support call. The choice propagated across the entire AirStation line and became a Buffalo signature. Practically, it's a gift: almost nothing else uses .11.1, so if that address answers, you're almost certainly on a Buffalo.
AOSS and the DD-WRT Models
Two Buffalo quirks worth knowing. First, the AOSS button, Buffalo's one-touch pairing, predates standard WPS and was beloved in the Nintendo DS and Wii era because those consoles supported it directly. Modern AirStations put both AOSS and WPS on that button; the usual WPS security caveats apply, so if every device already knows the password, disabling it costs nothing.
Second, Buffalo openly sold routers with DD-WRT pre-installed (the WZR series especially), a genuinely unusual move for a mainstream brand. If yours is one of those, the interface is DD-WRT's, not Buffalo's stock firmware, so the first-boot flow asks you to invent a username and password rather than accepting admin/password, and online DD-WRT guides apply to you directly. The gateway is still 192.168.11.1 either way.
