Hi, a BT engineer came to repair a fault on the building. It worked, so now the light is blue again and apparently it's working in most of my devices. However, on my laptop (mac) when I try to connect to my wifi network asks me for the password, but even if I enter the password I cannot connect. Restarting the hub makes the trick, but it's a pain in the **bleep**. Sometimes, after a few minutes my wifi is gone again and I would need to restar. What can I do?
