Mid 2010 iMac 27, on Sonoma but WiFi/cat 5 connection drops intermittently. Also Time Machine not working.

Had wanted to stay on Monterey, but forgot to turn off auto updates, and didn't realize it until too late. When running High Sierra was able to use both connections, WiFi and cat 5, at the same time, at least they allowed internet use, but on Sonoma only can have one active at a time. Anyone see an explanation for this? Another question is regarding heat output. Since I never paid any attention to how hot the top bezel was prior to upgrading, is there a way to see if the box is overheating? Have 1T SSD.

Also since this is a non-metal graphics card shouldn't I be having issues with the display, which is not the case? Although I don't using it for high graphics applications. Small brained human trying to understand how things work, thanks.
