192.168.11.1 Admin Login

Buffalo Technology (AirStation) routers are the primary brand that uses 192.168.11.1 as their default gateway IP address. Buffalo's extensive lineup of AirStation wireless routers — including popular models such as the WHR-G54S, WHR-G300N, WHR-HP-G54, WHR-300HP, WHR-300HP2, WZR-1750DHP, WZR-600DHP, WZR-1166DHP, WZR-HP-G300NH, WZR-HP-AG300H, WZR-D1800H, WCR-GN, WMR-300, WMR-433, and the WXR-1900DHP — all ship from the factory with 192.168.11.1 set as the default router IP. This makes 192.168.11.1 one of the most recognizable Buffalo-specific addresses in home and small-office networking. Beyond Buffalo, some DD-WRT firmware-flashed routers are also known to default to this address depending on the hardware and build used. It is used as a private IPv4 network address and serves as the router's gateway to manage all devices on your local network. To avoid address conflicts, only one device on your network should be assigned 192.168.11.1. Other commonly used default gateways in the same family include 192.168.1.1, 192.168.0.1, and 192.168.2.1.

How to Access 192.168.11.1

To access your router's admin panel at 192.168.11.1, open any web browser — Chrome, Firefox, Edge, or Safari — and type http://192.168.11.1 directly into the address bar. Do not type it into a search engine, as that will not take you to your router's login page. Press Enter and you should be greeted with a login prompt.

For Buffalo AirStation routers using 192.168.11.1, the most common default credentials are:

• Username: admin  |  Password: password
• Username: root  |  Password: (leave blank)
• Username: admin  |  Password: admin

These credentials are case-sensitive, so make sure you type them exactly as shown. Once logged in, you'll have full access to your Buffalo router's settings dashboard, where you can configure your Wi-Fi network name (SSID), wireless password, security protocols, DHCP settings, port forwarding rules, parental controls, firmware updates, and much more. Because 192.168.11.1 is a private IPv4 address, it is only accessible from within your local network — you cannot reach it from the internet.

If You Can't Access 192.168.11.1

If typing http://192.168.11.1 into your browser doesn't load the router login page, don't panic — there are several common reasons this can happen and straightforward ways to fix each one.

• You're not connected to the right network: Make sure your computer, phone, or tablet is connected to the same Wi-Fi network (or plugged into the same router via Ethernet cable) as the Buffalo router you're trying to manage. If you're on a different network, 192.168.11.1 will not be reachable.
• 192.168.11.1 may not be your gateway: Not every router uses this address. To confirm your actual gateway, open the Command Prompt on Windows (Start > type cmd > press Enter) and run ipconfig /all. Look for the Default Gateway field. On a Mac, go to System Preferences > Network > Advanced > TCP/IP. If the gateway shown is different from 192.168.11.1, use that address instead. You can also check our guide to find your router IP address.
• Browser auto-redirecting to a search: Make sure you type the full address including http:// — some browsers will search for the term instead of navigating to it if the protocol prefix is missing.
• The default IP has been changed: A previous administrator may have changed the router's IP from 192.168.11.1 to something else. In this case, you'll need to perform a factory reset (see below) to restore the default address.
• Firewall or VPN interference: Disable any active VPN connections or firewall software temporarily and try again.

If none of the above resolves the issue, proceed with a factory reset of your Buffalo router to restore all defaults including the 192.168.11.1 gateway address.

How to Reset Your Buffalo Router to Factory Defaults

If you've forgotten your login credentials for the 192.168.11.1 admin panel, or if the IP address has been changed and you can no longer access your Buffalo AirStation router, a factory reset is the most reliable solution. This will restore the router's default IP address (192.168.11.1), default username, and default password.

Standard Factory Reset Procedure (most Buffalo AirStation models):

1. Make sure your Buffalo router is powered on and fully booted up.
2. Locate the small Reset button on the back or bottom of the router. It is usually recessed inside a small pinhole to prevent accidental resets.
3. Use a straightened paperclip, a toothpick, or a SIM ejector tool to press and hold the Reset button for approximately 10 seconds. On some models like the WZR-900DHP, you may need to hold it for up to 15 seconds.
4. Watch the router's Power LED — it will begin to blink, indicating the reset process has started.
5. Release the button and wait for the router to fully reboot. This typically takes 60–90 seconds.
6. Once rebooted, the router will be restored to factory settings. You can now access the admin panel at http://192.168.11.1 using the default credentials (admin / password or root / blank).

Alternative Reset Method (DD-WRT flashed Buffalo routers): For Buffalo routers running DD-WRT firmware, hold the Reset button while plugging in the power cable, continue holding for at least 30 seconds, then unplug and replug the router. This performs a hard 30/30/30 reset that fully clears the NVRAM.

Important: A factory reset will erase all your custom settings — including your Wi-Fi name, password, port forwarding rules, and any other configurations. Make sure to back up your settings from the admin panel before resetting if possible.

Changing Your Router Password at 192.168.11.1

Keeping the default password on your Buffalo router is a significant security risk. Anyone who knows that Buffalo routers default to 192.168.11.1 with the password "password" or a blank root password could potentially access your network settings. Here's how to change it:

1. Log in to your router's admin panel at http://192.168.11.1 using your current credentials.
2. Navigate to the Administration or Management section of the dashboard. On Buffalo AirStation routers, this is typically found under the Advanced tab or directly in the System settings menu.
3. Look for the Password or Admin Password option.
4. Enter your current password, then type your new password twice to confirm it.
5. Click Apply or Save to update the credentials.

Choose a strong password that is at least 12 characters long and includes a mix of uppercase letters, lowercase letters, numbers, and symbols. Avoid using easily guessable information like your address or birthday. Once changed, store your new password somewhere safe — if you forget it, you'll need to perform a factory reset to regain access to 192.168.11.1.

What Is 192.168.11.1 and Why Does Buffalo Use It?

192.168.11.1 is a private IPv4 address that falls within the Class C private IP range defined by RFC 1918 (specifically the 192.168.0.0/16 block). Unlike public IP addresses, private IPs like 192.168.11.1 are not routable on the public internet — they exist solely within your local area network (LAN). This is why you can only access your Buffalo router's admin panel at 192.168.11.1 when you're connected to that router's network.

Buffalo Technology chose 192.168.11.1 as the default gateway for their AirStation product line as a deliberate design decision to differentiate their routers from the more common 192.168.1.1 and 192.168.0.1 defaults used by brands like Linksys, Netgear, and D-Link. This reduces the chance of IP conflicts when connecting Buffalo routers to other network equipment.

When your Buffalo router is set up with 192.168.11.1 as its gateway, it automatically assigns private IP addresses to all devices that connect to it via DHCP. These addresses fall within the 192.168.11.x subnet. For example:

• Your laptop might receive 192.168.11.2
• Your smartphone might receive 192.168.11.3
• Your smart TV might receive 192.168.11.4
• Your gaming console might receive 192.168.11.5

Every device on your network — whether it's a printer, a tablet, a smart home hub, or a security camera — gets its own unique IP address in the 192.168.11.x range. The router at 192.168.11.1 acts as the traffic controller, directing data between all these devices and the wider internet through your ISP's connection.

Related IP Addresses in the 192.168.11.x Subnet

The 192.168.11.1 gateway sits within the 192.168.11.0/24 subnet, which supports up to 254 usable host addresses (192.168.11.1 through 192.168.11.254). Several other addresses in this subnet are also commonly referenced in networking contexts:

• 192.168.11.2 — Typically the first DHCP-assigned address given to a device connecting to a Buffalo router at 192.168.11.1.
• 192.168.11.100 — Used as the default IP on some Buffalo WHR-1166DHP4 models; also a common static IP assignment for network printers and NAS devices.
• 192.168.11.254 — Sometimes used as an alternative gateway address on certain network configurations within this subnet.
• 192.168.13.1 — Another Buffalo-specific default IP used on select models, with credentials delivered on an information card included in the box.

If you're managing a Buffalo AirStation network and need to assign static IPs to specific devices (such as a home server, printer, or security camera), it's best practice to assign addresses in the upper range of the subnet (e.g., 192.168.11.200–192.168.11.250) to avoid conflicts with DHCP-assigned addresses, which typically start from 192.168.11.2 upward.
