Since I had upgrade to TV 360 box, I have had problems with hearing a high pitched noise. I have now given up and totally disconnected the TV box and switched the hub 3 to modem mode. I don't think hub 3 can cope with being in router mode along with the software that virginmedia have downloaded to it for TV box. However, there is now a buzzing noise whenever a phone is connected to hub 3. I am therefore thinking of replacing the phone adapter and the phone to see if it helps before complaining about the hub 3 again. Please can you advise:
1) Is the phone adapter supplied by virginmedia a RJ11plug to BT socket plug?
2) Please can you advise what type of landline phone will connect to hub 3. Should it be a DECT and VOIP and are gigaset phones compatible?
Thank you for any advice you can give me.

You would be most likely to experience mains interference if the equipment was piled on top of each other and cables from different equipment wrapped around each other. If the equipment is separated by a metre distance, that kind of interference would be less likely (e.g. in a past topic, the customer had the hub and cordless phone base placed on top of a computer tower and experienced interference which improved when the equipment was separated).
You could also try running individual items of equipment to see if the hum is present on the phone line. e.g. turn off other equipment nearby. Run just the VM hub and the phone and see if the hum is present on the phone line. If no hum, turn on other items of equipment, one at a time, and see if another item causes the hum to appear on the phone line.
High pitched sounds from equipment are often due to individual electronic components inside the units (often noticeable with power supplies). See if you can identify if it is the 360 TV unit itself or the 360 TV power supply that is making the high pitched noise.
Suggest you borrow a phone and see if that improves the interference any. Then post back on here with the outcome.

If VM's equipment is making high pitched noises and buzzing noises, it sounds as if you might have faulty VM equipment. In answer to your questions
1) Yes RJ11 plug to BT socket is the adapter
2) Any current/modern standard telephone should work via a hub phone connection. VOIP is often incorrectly used to describe the connection and it causes confusion.
Is your VM hub placed closely in or around other pieces of equipment? Are the phone cables bundled or wrapped around other equipment?
A humming sound on the phone line could be mains interference from other items of equipment. Try separating the VM hub and phone/cables from other equipment and see if that helps with the hum.
Would suggest you try borrowing a phone from a friend/family member/neighbour to do your tests. That would save you the time/effort/expense of buying one if the test shows your existing phone is OK.

Hi Miss_Frustrated,
Can you please try separating the equipment further from each other just to test this.
If there is no difference then we can look to see if we need to replace the Virgin Media equipment.

Hi Martin,
Thank you for your reply.
I have bought a new phone and phone adapter to see if things improve. I have not connected up the TV box yet.
Is it normal for the VM hub 3 ethernet port (now in modem mode) to continually flash even when there are no devices connected to the router?

Thanks for coming back to the thread, what colour is the light flashing?
Kind regards,

Thank you for your reply regarding electrical interference.
I have moved the router to a different room in the house and things have improved slightly.
Would you advise using shielded or unshielded ethernet cables from modem to router and flat or rounded cables?
on 26-09-2022 14:39
It is flashing green continually.
on 26-09-2022 14:49
Can you confirm if it's the port light or the main LED light flashing please?
Kind regards,
