This guide shows you how to reset your O2 TG582n router to factory default settings. A router reset is a much bigger deal than a router reboot. A reboot happens every time a router loses power. A Router Reset completely erases the router and returns it to factory settings.
Warning: Make sure that you fully understand the following before resetting your router. A router reset will affect the following settings:
- The router's username and password are reset to factory defaults.
- All WiFi settings are reset, including network name and password.
- All ISP settings will reset to default, and you may have to contact your ISP.
- Any parental controls, firewall settings, or port forwards will be removed.
A router reset should be considered the last resort when you cannot log in to your router any other way. You should be sure that you have tried to at least recover your router password using our Router Password Finder before resorting to a router reset.

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.

There is usually a small reset button located on either the back or the bottom of a router. Look at your router and try to find something that looks like this:
Even though yours may look slightly different, you need to look for a tiny button. You may need a paper clip to push the reset button.
Hold the reset button down for 10 seconds and watch the lights. After a few seconds the lights should blink differently. When this happens, the reset is complete. 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 O2 TG582n router.
This last step should only be taken if you have tried everything else, such as using our Router Password Finder software, which can recover lost or forgotten router passwords.
Login to the O2 TG582n
Now you need to log in using the factory default username and password. We have a TG582n Login Guide with all this information ready for you.
Change Your Password
Do not forget to change your router's default password when you log back into it. Leaving a router password set to default is a very serious security risk. Our Choosing a Strong Password guide can help you pick a strong password for your router.
Tip: Write your new password down on a note and tape it to the bottom of your router for future reference.
