This is the reset guide for the Huawei HG8121H router. This is not the same thing as rebooting a router. Every time your router loses power it reboots. This is very different from a reset, which erases a router completely and returns it to factory default settings.
Warning: This is not a step to be taken lightly. The following settings will be changed in your router:
- The router's login and password are reset to factory defaults.
- All WiFi information such as network name, password, and authentication method are erased.
- Your ISP username and password will be reset, and you may have to contact your ISP.
- Any firewall settings, parental controls, or port forwards that you have configured will be removed.
A router reset should be considered the last resort when you cannot log in to your router any other way. Make sure that you have tried to recover your router password using our Router Password Finder first.

Use a VPN Instead
Have you considered using a VPN instead of forwarding a port? For most users, a VPN is a much simpler and more secure choice than forwarding a port.
We use and recommend NordVPN because not only is it the fastest VPN, it includes a new feature called Meshnet that makes forwarding a port no longer necessary for most applications. With NordVPN Meshnet, you can connect to your devices from anywhere in the world, completely secure, over a highly encrypted VPN tunnel.
When shopping for a VPN, make sure that they meet the following criteria:
- Your VPN provider should have a no-logs policy. This means that they do not keep any logs of any kind.
- Make sure that your VPN provider has lots of exit nodes all around the world.
- Check that your VPN will not affect your speed.
- Verify that your VPN provider uses WireGuard as the underlying protocol.
- Many people prefer a VPN provider that is not based in the United States.
This is the list of requirements that we used when we were shopping around for a VPN provider. There are lots of free, shady VPN providers out there that we looked at and dismissed.
Based in Panama, using diskless servers, and with over 6,100 servers in 61 countries, we can safely say that NordVPN satisfies all of these requirements.
Once you've set up your NordVPN account on multiple computers and enabled Meshnet, you can seamlessly access all of your devices as if they were on the same network. You don't even have to log in to your router. It's very simple.
Every time you click on one of our affiliate links, such as NordVPN, we get a little kickback for introducing you to the service. Think of us as your VPN wingman.

You can usually find a small reset button on either the back or the bottom of a router. Look at your router and try to find something that looks like this:
Reset buttons are usually tiny. Yours may look slightly different than this. You might find a pinhole on the back of the router that requires a paper clip to push the button hidden under it.
Watch the lights on the front of your router and hold the reset button down for about 10 seconds. Notice how the lights on the front of the router are blinking. When the lights do something different, the router is reset. You can hold the button down as long as you like, it will not hurt anything.
Just don't forget that this will totally reset your Huawei HG8121H router.
Be sure to only reset your router if you have tried everything else, such as running our Router Password Finder software, which can find your lost or forgotten router password for you.
Login to the Huawei HG8121H
Now you need to log in using the factory default username and password. Just follow our HG8121H Login Guide to find all of the information that you need.
Change Your Password
Do not forget to change your router's default password when you log back into it. Since factory passwords are well known, it's a huge security risk to leave your router set to the default. Our Choosing a Strong Password guide talks about choosing a strong password for your router.
Tip: After creating this new password, we highly recommend writing this down on a post-it note and attaching it to the bottom of your router for future reference.
