How to set up O2 Home Broadband on your own router


If the you want to use O2 Home Broadband with your own router, you may need to enter some settings for it to work properly.


Some routers come set up correctly. Others will come with a set up CD or wizard to help you get connected. You'll need to refer to the manufacturer's instructions to find out exactly how to enter these details.


If your router has an ADSL2+ setting, make sure it's enabled. ADSL2+ is the technology we use to get a high-speed connection into your home.


There are different settings for our service depending on whether you are using our standard service or our Home Access service. Settings for both are provided below:
