Hello,
I have a similar problem I’m hoping someone could help.
We installed our WiFi on the 30th December. I received a text saying it was activated and ready to use at 11am on 31st December. It remained flashing purple from then and is still flashing purple.
We have a single master socket with a filter. A person from BT checked our phone and it worked fine to prove the connection works. Waiting for an engineer to come but was looking for help from elsewhere.
If you have a dial tone and phone working ok then just need to wait for engineer visit
