In relation to my previous post on replacing a TalkTalk router with a Cisco 800, the steps below are for doing the same with BT Infinity.
Openreach Modem: Huawei HG612
BT Home Hub 5 – Type B
There is plenty information around on making this change but as I couldn’t find one blog post with all the information, I decided to write one. If you have any questions feel free to comment below.
Unlike TalkTalk fibre, BT Infinity uses PPPoE and therefore requires a Dialer interface, authentication method/credentials and a few other changes for this to work. For the username you can use ‘email@example.com’ as I did below and the password can be anything, I used ‘bt’.
