Wireless Internet speed slowed to a crawl

Hey curious if anybody is able to look at these and can see the problem I’m having. Right before I left for Christmas Break I came home from work and noticed all smart devices were knocked out at my house. Thought it was an outage and would come back to everything fine. Week later problems still persist. Wifi will drop out frequently when it is on speed tests are waaay slow. If I ethernet into a computer runs great. Looking like a wifi problem? Logged into the modem and these are what I was pulling.

Modem is a Motorola MB8600
