Hi,
I joined G.fast Fibre150 beginning old Dec. Initial sync speed was 140Mbps but every day it drops and it ended up at 89Mbps over last few days.
I contacted Talktalk who did a line check said everything is fine so had to call out an engineer to investigate. I have it booked on 29th but has not received any confirmation text or email so not sure if someone will still be coming due to current new COVID19 restriction in South East.
I have unpluged my powerline wifi extension as heard that it may cause interference. The BT modem was plugged into test socket with filter last 4 days and I did a modem /router restart after turning them off for 30 minutes. Now the download speed come back up from 89Mbps to 110Mbps.
It is still lower than the garunteed speed of 117Mbps I signed up for. I'm still within the first month to cancel my contract.
What should I do? Wait for the engineer to investigate (if they are still coming) and paying the cost or cancel it and change provider? Not sure other g.Fast provider would come across the same problem.
