In the last couple of months I've been experiencing an increasing degradation in router range of WiFi signal. Rooms in the house where the WiFi signal was powerful and the sustained connection speed had no problems whatsoever are now impossible to connect from. Although devices still appear as connected to the network, there's absolutely no traffic going through.
I discussed this with someone from the customer service but I got no reasonable answer at all. Just a template email about moving the router from behind TVs and nonsense like that. My router has been in the same place since I installed it, and there's been no other change to the setup. I have tried all proposed "solutions", turned it off and on again, reset the router to factory settings... Nothing works.
I can only assume this is an issue of the Hub's hardware degrading and failing to provide the same range as before. I would like to know what's the process for exchanging my current hub for a new one that actually does its work, as I WFH and I need a reliable connection speed at my desk.
