Welcome to TPG Community!
We were able to locate your account using your community details and understand that the case was escalated to our Engineering team.
Based on the notes, the test that was performed by our Tech team doesn't show any issues within the copper network. There's a possibility that internal wiring or the modem itself was at fault that causes the issue.
In order to check on this further, our Engineers arranged a TPG technician that will visit your premises on Monday to have this resolved once and for all.
In the meantime, if you have any further enquiries or require general information on the matter, contact us here and we'll be sure to get this coordinated for you.
