192.168.11.1 is a private IPV4 address. It’s one of the addresses from the block of private addresses within Class C. Just like any other private IP address, it can’t be routed on the internet and it’s used within home and local area networks. It’s used by some manufacturers as a default gateway address.
Manufacturers Assigning 192.168.11.1 to Their Modems/Routers/Access Points
This address is preferred by modem and router manufacturer called Buffalo. If you have their router/modem/access point, there’s a great chance that the default gateway address is 192.168.11.1. Some of Buffalo devices using this address are WPL-05G30 (access point), WBMR-HP-GN, WBMR-G300N (modems),WCR-HP-G300,WXR-1900, WYR-G54, WZR-G108, WZR-HP-G54, WZR-G108,WHR-G54S, WBMR-HP-G300H (routers), etc. Some other manufacturers like ReadyNet, Sony, and ZuniDigital use this address, too.
192.168.11.1 as a Default Gateway
As we have already said, there’s a great chance that your router’s default gateway is 192.168.11.1 if you are using some Buffalo router or modem. If you are not sure what’s your router’s default gateway, there’s a simple way to check it in any operating system. Once you are sure that this is your default IP address, you can use it to access your router’s setup (configuration) page. You just have to enter this IP address in your browser and log in. When you enter the correct username and password, click on Log In, and the configuration page will appear (see the example below).
Step 1 – Type in the address and press ENTER. The login page will appear.
Step 2– Enter the correct username and password. In our case (WZR-HP-G450H), the username was root and the password field was blank. If you have some other router/modem, you will have to enter the default username and password for that device (some of the common combinations for Buffalo devices are root-blank, admin-password, root-password, admin-admin, etc.). After that, click on Log In.
Step 3 – After logging in, the configuration page will open and you can start configuring your home network.
There are a few important things to do during the initial configuration of your network. First, you should change your wi-fi network name (SSID) and password. In order to do that, click on WIRELESS tab and select Basic (11n/g/b). Type in the wi-fi network name you like in the SSID field, select the authentication method and encryption (WPA2/PSK and WPA2/PSK mixed-mode are recommended) and enter your new password.
You can also use this page to change your router’s username and password, adjust DHCP pool (set the number of available addresses, change lease time, block some IP address, make a DHCP reservation and assign a static IP address to some of your computers, etc.)
192.168.11.1 – Troubleshooting
The most serious issues with any router are software and hardware malfunctions but the most common issue is caused by a simple typing mistake. If you can’t enter the login page, you should check if you have entered the correct address. People often type in 192.168.1.11 or 192.168.1.1 instead of 192.168.11.1 and if you enter the wrong IP address you will get nowhere. If you can’t pass the login page you should check the default username and password of your router and if you have changed the defaults and can’t remember them, you have to reset the router (but you will have to configure your network again if you reset it).
