Buffalo Router Login: IP, Username and Password
Log in to Buffalo at 192.168.11.1 with admin and password, or root and blank on older models.
Connect to your Buffalo router first by WiFi or cable. Some AirStation models use root with no password.
Buffalo AirStation routers open their settings at 192.168.11.1, an address most other brands do not use. Some extenders and access points use 192.168.13.1.
The most common default login is admin and password, while older AirStation firmware uses root with an empty password. Here is how to log in, change WiFi and reset.
The fastest way in: tap the login button in the box at the top of this page, then sign in with the details on your router label.
How to log in to your Buffalo router
- Connect your phone or computer to the router WiFi, or plug in an Ethernet cable.
- Open a browser and type http://192.168.11.1 in the address bar.
- Enter the username and password from the table below or the router label.
- Once logged in, change the admin password and use WPA2 or WPA3 for WiFi.
If the page does not open, check your Default Gateway with our Router IP Finder. ISP builds sometimes use a different address.
The 192.168.11.1 address is the one I try first on any Buffalo that will not open.
Buffalo default IP, username and password
| Model or type | Login address | Username | Password |
|---|---|---|---|
| AirStation routers (newer) | 192.168.11.1 | admin | password |
| AirStation routers (older) | 192.168.11.1 | root | (blank) |
| Extenders and access points | 192.168.13.1 or label | admin | password or label |
| Japan models | 192.168.11.1 | admin | On the label |
If neither login works, check the label. Japanese market models often print a unique password. The Japan-model note is the label detail I check first on an AirStation. Check the setup card in the box too, since newer models print their own password there.
How to change the WiFi password on a Buffalo router
- Log in at 192.168.11.1.
- Open Wireless Config or Wi-Fi, then Security.
- Choose WPA2-PSK AES and enter a new pre-shared key.
- Click Apply and reconnect devices.
Easy Setup on the home page also lets you change the WiFi name and key. Need a strong key? Try our WiFi Password Generator. For me, Easy Setup is where every Buffalo WiFi change starts.
Buffalo login problems and fixes
- 192.168.11.1 will not load: make sure you are on the router WiFi, not mobile data or a VPN, and type http:// in front.
- Wrong password: check the label first. If you or your ISP changed it, the defaults will not work.
- Page loads but login fails: clear the browser cache or try a private window. Some routers lock you out for a few minutes after several attempts.
- Router from your ISP: the provider may manage it. Their app or support line can reset the admin password.
- Still locked out: a factory reset restores the label login, but erases your settings.
I start with the label check whenever a Buffalo login will not work.
How to reset a Buffalo router
- Keep the router powered on.
- Press and hold the reset button for about 3 to 10 seconds, until the lights flash.
- Release and wait 2 to 3 minutes.
- Log in with the default details and set up WiFi again.
Hold the INIT or RESET button until the DIAG light flashes. The DIAG-light flash is the signal I wait for before I let go of the button.
Buffalo AirStation basics
Buffalo routers (AirStation) are especially common in Japan, and still found in homes elsewhere. They open at 192.168.11.1. Older models use admin and password; newer ones print a unique password on the label. The AirStation app, formerly StationRadar, manages the same settings from your phone.
Buffalo also makes extenders and NAS drives (LinkStation, TeraStation), which have their own separate logins. The NAS-separate-login detail is the one I flag first for anyone hunting a Buffalo box.
Settings worth changing on a Buffalo router
- Change the admin password.
- Set WiFi to WPA2 or WPA3 with AES.
- Disable AOSS/WPS if you don’t use it.
- Check for firmware updates on Buffalo’s regional support site.
- Turn off remote access unless you use it.
The remote-access-off step is the one I never skip on a Buffalo I touch.
Buffalo NAS and extenders
If you’re trying to log in to a Buffalo LinkStation or TeraStation NAS, not a router, use the NAS Navigator app to find it on your network. The NAS has its own admin login, separate from any router. Buffalo extenders usually have a setup network and their own web page during setup.
The NAS-Navigator tip is the step I point at first for a Buffalo NAS login.
Buffalo router won’t load 192.168.11.1
- Check the Router/AP switch is set to Router (in AP mode, the address changes).
- Connect directly with a cable.
- Make sure your device is set to obtain an IP automatically.
- Try another browser or clear the cache.
The Router-AP switch check is the step I take first when 192.168.11.1 will not load.
