Buffalo AirStation Router Login: Access Your Admin Panel

Buffalo is a Japanese networking brand, and AirStation is its line of wireless routers. They use an unusual login address, 192.168.11.1, rather than the 192.168.1.1 or 192.168.0.1 most brands use, which is the first thing that trips people up. The credentials also vary by model generation. This guide covers the login, the different defaults, and how to fix access problems.

How to Log In to a Buffalo AirStation

1. Connect your computer to the router, over Wi-Fi or with an Ethernet cable into a LAN port. The default Buffalo Wi-Fi network usually looks like Buffalo-G-XXXX or Buffalo-A-XXXX.
2. Open a web browser such as Chrome, Firefox, Edge, or Safari.
3. Click the address bar at the top of the browser, the bar that shows the web address. Do not use the search box.
4. Type 192.168.11.1 and press Enter. Some models also accept the hostname http://airstation.buffalo.jp, which redirects to the same admin panel.
5. Enter the username and password. See the table below.
6. Click Log In to reach the router settings.

Default Username and Password for Buffalo AirStation

The defaults depend on your model’s generation, which is the main source of login trouble.

Buffalo model type	Login address	Username	Password
Most AirStation home routers	192.168.11.1	admin	password
Older models (such as WZR series)	192.168.11.1	root	(blank)
Some models	192.168.11.1	root	password
Newer WSR and WXR series	192.168.11.1	admin	the password on the label

The most common default is admin with the password password, both lowercase. Older models often use root with a blank password, so you leave the password field empty. Newer WSR and WXR series routers no longer use a fixed password, and instead print a unique one on the router’s label or setup card.

The credentials are case-sensitive, so admin is not the same as Admin, and password must be typed exactly. If you have a unique label password, check every character carefully, and make sure Caps Lock is off.

The label on the bottom or back of the router, or the included setup card, lists the IP address, username, password, SSID, and Wi-Fi key for your exact unit, making it the most reliable source.

Why Buffalo Uses 192.168.11.1

Worth knowing, since it explains a common confusion. Buffalo deliberately chose 192.168.11.1 as the default gateway for the AirStation line to differentiate its routers from the more common 192.168.1.1 and 192.168.0.1 used by brands like Linksys, Netgear, and D-Link. So if you tried those addresses and got nothing, that is why.

How to Change Your Buffalo Wi-Fi Name and Password

Changing the Wi-Fi key is the most common reason people log in.

1. Log in at 192.168.11.1.
2. Select Wireless, then Basic, which on some models appears as Basic(11n/a) for the 5 GHz band.
3. Enter your new network name in the SSID field.
4. Enter your new Wi-Fi password in the WPA-PSK (Pre-shared Key) field, sometimes labeled Encryption Key on other models.
5. Click Apply.

After saving, every device drops off the Wi-Fi and reconnects with the new key. If your router is dual-band, repeat for the other band. Use a password of at least 12 characters with no personal details. Our full guide on how to change your Wi-Fi password walks through it for any router.

How to Change Your Buffalo Admin Password

Because the Buffalo defaults are well known and published widely, changing the admin password matters for security.

1. Log in at 192.168.11.1.
2. Go to the Administration or Management section, usually under the Advanced tab or in System settings.
3. Find the Password or Admin Password option.
4. Enter your current password, then type your new one twice to confirm.
5. Click Apply or Save.

Store the new strong password somewhere safe, because if you forget it, a factory reset is the only way back in.

What to Do If You Cannot Log In

The page will not load. Confirm you are connected to the Buffalo router and using the right address.

• Remember it is 192.168.11.1, not 192.168.1.1. The extra digit is easy to miss.
• Confirm your gateway. On Windows, press Windows + R, type cmd, run ipconfig, and read the “Default Gateway” line. You can also run ping 192.168.11.1 to check the router responds, or find your gateway’s IP on any device.
• Try the hostname http://airstation.buffalo.jp if the IP will not load.

The password is rejected. Try both admin/password and root with a blank password, since the defaults vary by model. Check the label for a unique password on newer WSR and WXR units. Remember the login is case-sensitive.

You are not on the router’s network. 192.168.11.1 is a private address that only works from within your own network. It cannot be reached from the internet or over mobile data.

How to Reset a Buffalo AirStation to Factory Settings

A factory reset erases everything and restores the default IP address, username, and password. Use it only when you are locked out.

1. With the router powered on and fully booted, find the recessed Reset button on the back or bottom.
2. Use a paperclip or SIM tool to press and hold it for about 10 seconds. Some models, such as the WZR-900DHP, may need up to 15 seconds.
3. Watch the Power LED, which will blink to show the reset has started.
4. Wait for the router to restart, then log in at 192.168.11.1 with the default credentials for your model.

Conclusion

The key to a Buffalo AirStation login is the address: 192.168.11.1, not the 192.168.1.1 most brands use, which is why the page often seems not to exist. From there, admin with the password gets most people in, while older models use root with a blank password and newer WSR and WXR units use a unique password on the label. Once you are in, change the default admin password, since Buffalo’s defaults are published widely and anyone on your network could look them up.
