Smart TV and Desktop Computers have to force re-connect to Smartthings Wifi Hub daily

I’m having a problem with the newest version of the Smartthings Wifi Hub (v3)- almost every time I turn on my Sharp Smart TV or my Microsoft Surface Studio, they show no internet connection- and I have to select my wifi network and let the device re-connect. I also notice that the wifi connection randomly drops on my Pixel 3a, Surface Go and Pixelbook, but they will usually come back in a few seconds. I live in a small house and have good signal strength from what I can tell. I may be having issues with interference, but I can’t seem to see how to change the broadcast channel.

Thanks for any ideas!
