Hi. We've had our Vodafone broadband for about a month now. 500mb full fibre with the ultra hub. The hub is making a high pitch noise which is quite noticeable as it's on top of my telephone unit beside the fibre connection. I messaged Vodafone and they said it's normal. I have been with just about every other isp and never had a router make any noise. Can anyone confirm if the ultra hubs are just noisy. It's like a high pitch electrical interference noise.
