I've located your account using your Community details and has run remote test.
Currently, the test results does not show a physical fault with the line or with the network.
I do recommend that we have one of our technicians give you a call to resolve your issue as your service may be affected by other factors.
Please let us know your best time and contact number via Private Message so I can get a technician to call you.
