Use the "Check service status" link at the top of this page for area faults. If this does not show any faults then likely there is a signal issue that is only affecting your property. Virgin does not monitor individual connections, so you will need to ring faults (150 from any Virgin phone), & they will run some tests on your box & connection. You can also wait for the Forum Team to respond here, which can take a while longer (2 -3 days).
