wifi always dropping

Hi,

my wifi is constantly dropping - making video calls drop off and alerting my Ring alarm to wifi loss.

My BQM graph shows lots of yellow spikes and some red blocks.

I have checked all the cables and reboot regularly

Re: wifi always dropping

You'll need to wait for a forum mod to reply.

Are wired connections also dropping?
