I tried to go the the device manager and there it shows that the mediatek wifi 6 mt79.. has a code 12 which is it does not have enought free space or something ?

Si tienes este problema lo mejor es reemplazar la tarjeta de Wifi, cualquier cosa que hagas lo que dicen en este post es una solucion temporal, lo mas eficaz y permanente es cambiar la tarjeta Wifi (El problema son las altas temperaturas). Aunque lo mejor por ahora que podrias hacer para ahorrarte dinero es cambiar el ssd a otra ranura/slot para evitar que este haga contacto con el Wifi. Literal he hecho de todo y nada funciono xD, luego de hacer lo que te acabo de explicar justo ahora sigue ocurriendo el problema pero solo desaparece el Bluetooth, si empiezo a jugar juegos mas exigentes + temperaturas altas el wifi desaparece, eso si el problema es mas "comodo" porque al rato vuelve o con solo reiniciar basta. Por lo general, ahora en mi caso, el bluetooth desaparece al estar conectado al cable porque se conecta el GPU y empieza a calentarse.  Asi que opte por comprar otra tarjeta Wifi porque la mia ya esta demasiada perjudicada ya que han pasado 2 veranos. Espero te ayude! :8

I tried this solution, but the Wi-Fi kept disappear after 4-5 minutes. Out of curiosity, I moved the SSD used for gaming to the main slot. The problem was that the Wi-Fi adapter was overheating due to its proximity to the gaming SSD. Moving the SSD to a different slot fixed the issue, and the Wi-Fi has been stable for a month since then.

bruhhh, I gave up. I posted here while ago and that was the last thing I did. Moved the ssd to another slot, the wifi and BT kept going well during days but then the problem just appear, Heat/High Temperatures damages this crappy ass wifi/BT card, I'll say whoever has this card should immediately move out  the ssd to avoid this issue. I had mine during 2 summers in the same slot so makes senses that it is already damaged due to heat. So I end up getting the Intel AX210.
