@virginmedia I've just done the test above and it says it needs to send an engineer. This is the same as last week. The engineer came and said the issue was beyond the building I live in.
Please look into that part of the system.
@virginmedia I have 4g on my phone. Nothing from my router. The Virgin engineer came on Saturday and said the problem was low signal coming from beyond the building. Maybe an amplifier or something.
