I'm sorry to read you are having an issue with the wireless signal.
From checking your connection, the Modem SNR (signal to noise ratio) for downstream is too low at 28 dB and for this I would like to arrange an engineer appointment to check this over. I've sent you a PM (purple envelope icon, right corner) with some details for you to confirm please.
This may or may not be the main cause of the issue, however it does need to be looked into. In the meantime, have you tried changing the wireless channel to improve the signal?
Thanks for the reply and confirming your details, I appreciate it.
When checking your account, there has been an SNR fault reported in your area which is causing intermittent connection. The reference number is F005222923 and has a review date for later this afternoon. You can check our Service Status page for updates.
Once this fault has been closed as resolved, I will check your connection again and if there is still an issue I can book the engineer appointment for you.
I can see that the fault in your area has now been closed as resolved. However the downstream power levels are too high and I can arrange an engineer appointment to check this over for you. I've sent you a PM (purple envelope icon, right corner) with some details for you to confirm please.
