Likely that it is related to Bluetooth as well. Especially if you have AirPods connected. I noticed the wireless connection quality degrades significantly when the device is connected to an AirPod.

Have you tried flushing the DNS cache?

This has almost become a meme at this point. Anyone in the office who has a problem with their internet on the Macbook, I just send them this:

sudo dscacheutil -flushcache;sudo killall -HUP mDNSResponder

yep, been a part of my bash aliases for about a decade now?

My asus wifi card in my pc does that too

I haven't seen mine lose Internet entirely, but I have seen it randomly switch between the two Wi-Fi networks I have set up where I live. I eventually got frustrated with this and then told it it can't automatically connect to one of them anymore.
