internet and wifi constantly dropping

The last 3 weeks the internet and wifi constantly dropping several times a day. App says no problems or outages and then claims i have higher speeds but all devices drop constantly. I work from home and paying for higher speed tier but service has been terrible. Customer service on the phone is a joke and I've wasted time and gotten "disconnected" a few times (by mistake im sure) when calling in to complain about it. then I have to start over again. ridiculous. what is happening?

-FYI did all necessary steps. rebooted, checked connections, etc. Been around long enough to do all that BEFORE you even call so stop making me do it every time i call in.
