After some hours of trying to figure this out, it seems my Mate 20 Pro (EMUI 9.1.0) is knocking out wifi to all other devices around the home. I've turned off Wifi (using just 4G) and then running speed tests on by laptop, streaming sonos and services such as Prime and Netflix and it's all working fine. As soon as I connect my Mate to the same Wifi network everything else stops and the Mate itself can't access the internet either. I had a BT HomeHub 6, then got offered a HomeHub 4 from BT as the HH6 is not suitable for our home network. Not sure what else to do? Desperately need some help and thoughts on this please?
Thank you in advance!!
