Re: BT Home Hub 6A not connecting on Plusnet
@Route66 Welcome to the forum.
There are two things that can stop it connecting.
1. Older firmware versions (which updates when it connects) will not work if you have a special character in your Plusnet password. Ignore Plusnet and just use alpha numeric characters for this.
2. You plug the DSL cable in too early. This must not be connected until you have entered your Plusnet user name and password and it's trying to connect.
Thanks again Baldrick for pointing me in the right direction.
It was the Plusnet password at fault. Once I changed my account log in on the Plusnet web site, then entered my new password in the router all went well.
