I have made some checks. I am sorry, there's currently and SNR issue showing in your area. The estimated fix date is 11th December 2019 at 3:25pm. I am sorry for any inconvenience this may be causing you.
Since Xmas I've had connectivity issues and I'm not sure if it's to do with this old SNR issue.
My devices periodically lose connection to the router, often when I stress my uploads/downloads (e.g. uploading large videos). The wifi stops responding and it even hangs when I try to access 192.168.0.1
I haven't changed anything and I've tried flushing my dns, renewing ipconfig, rebooting the router, etc.
