I've noticed my hub is making a hissing noise, that gets worse when a few people are on the wifi. Sometimes it drops to a faint beeping, like a cricket as some other threads on here have complained about. I'm not sure how long it's being doing this but it's now loud enough to notice it regularly.
I've tried the previous solutions of unsyncing wifi and just turning off the 5g etc but it still continues buzzing away. Anyone got any other tips or is it best to ask for a replacement?
