Buffalo WHR-HP-GN Login: Default IP, Username & Password

I set up a Buffalo WHR-HP-GN, known in searches as whrhpgn, and the login page asked for a username and password I had not seen yet. The box had no password printed on the label, and I did not want to guess and lock myself out. This guide gives you the address to open, the login details that work, and the steps I use when the page will not load.
Log in at 192.168.11.1 with the username root and a blank password. If that does not work, try admin / password — the other common Buffalo default.
Here is the fastest way in:
IP Address: 192.168.11.1
Username: root
Password: (blank)
This button opens our 192.168.11.1 guide — the address only works when you are on the Buffalo WHR-HP-GN network.

How to log in to the Buffalo WHR-HP-GN
In my experience, this part goes fast once you know the username rule. The WHR-HP-GN uses root as the username and leaves the password blank, so there is nothing to look up on the label.
- Connect your phone or computer to the WHR-HP-GN Wi-Fi, or plug in a cable.
- Open a browser and type 192.168.11.1 in the address bar.
- Sign in as root and leave the password box empty, then press Enter.
- Open the settings page you need, make your change, and save it.
I set a new password right away and write it down with my other home notes. A router left on its factory login is easy for anyone on the network to open.
What 192.168.11.1 is
192.168.11.1 is the local address for the admin page on Buffalo AirStation routers. It is not a public website. It only opens when your device is on that Buffalo network.
From this page you can change the Wi-Fi name and password, see which devices are connected, and update the router. If you are not sure which Buffalo model you own, see our router brands page.
If 192.168.11.1 will not open
When the page will not load, I check the basics first. A small typing slip or the wrong network is the cause most of the time.
- Make sure you are on the WHR-HP-GN Wi-Fi, not on mobile data or a neighbour network.
- Type 192.168.11.1 with no www and no https in front of it, or try a different browser.
- If root with a blank password fails, try admin / password — the other common Buffalo default.
- Restart the router, wait two minutes, and try again.
If you are not sure which address your router uses, try our Router IP Finder. If the page still will not open after a restart, the router may need a reset with the small button on the back.
