Welcome to the Community Forums! Thank you for your first post.
I'm sorry to hear you've been having some issues with your broadband/WiFi service recently. I've been able to find your account and can see that there are some issues affecting your downstream channels which will require an engineer visit to put right.
I'll pop you over a PM so I can take some more details and get this arranged for you.
Please check out the purple envelope for a message from me.
