Welcome to TPG Community!
I've searched for your account using your Community details and was able to find a match.
I've ran remote tests and the results does not show a clear conclusion that there's a fault with the line outside.
I would recommend to have one of our technicians call you to do real time testing to eliminate any possible equipment, Wi-Fi limitation and bandwidth sharing issue.
Please let us know your best contact time and number via PM and we'll have this arranged for you.
Thanks for sending your contact details via PM.
I've now arranged a call from one of our technicians tomorrow, Wednesday 23 May between 3:00pm - 4:00pm.
We would appreciate if you'll be at home during the time of call as our technicians would like carry out simple checks with you to eliminate any possible equipment issue. If this time is not suitable, please let us know and we'll have this rearrange for you.
By "a call" do you mean that the technician will call me on my phone, or that the technician will visit my premises? I am assuming that you mean that the technician will visit and that I will need to be at home. I will leave work at 2:30pm and should be home by 3pm.
All the best, Paul
