How to reset the O2 wireless box

If your wireless seems unreliable or your Internet connection appears to be running slowly, it might be worth resetting your O2 wireless box.


The easiest way to do this is to simply turn it off. Wait for 30 seconds and then turn it back on again.


If this hasn't helped, we can perform a factory reset by going into the O2 Home Broadband advanced settings:


  • Make sure your computer is connected to the O2 wireless box, either wirelessly or via a network cable.


  • Open your web browser (eg Internet Explorer).


  • Type http://o2wirelessbox.lan into the address bar and press 'Enter.'


  • The O2 Home Broadband advanced settings should now load.


  • If this doesn't work, try typing into the address bar and pressing 'Enter.'


  • Once you've opened the O2 Home Broadband advanced settings, choose 'O2 wireless box' from the menu on the left of the screen.


In the main area of the screen you’ll see the subheading 'Pick a task.' You might have to scroll down the page to see it. Underneath this heading, click on 'Return To Factory Default Settings'. This will remove any settings you have changed or set up by yourself, so if you have made any changes to the settings on the box these will be lost and will need to be set up again.
