We have put together a short survey to capture your feedback in terms of what BT can do when you experience home Wi-Fi issues. We would appreciate it if you could take a couple of minutes to complete a short survey. Read more from here, Fix my home Wi-Fi
I am so sorry to hear that this is still ongoing.
I will be chasing the developers again and I will message you each day I'm in office until it's fully resolved. Please feel free to post up here if you need me at any point. If I'm not here one of my team will tell me when I'm back in office. I'll be in touch with you tomorrow.
