Dude I was so scared(I have a tuff 15 ) thinking I was the only one , I was having this problem earlier but it came back randomly but now its worse as my screen randomly freezes after starting and goes to a blue screen after 5 mins and at the same time the wifi symbol disappears and it does not appear even after restarting , I'm goddamn fed up of this laptop having weird problems that noone has the solutions to.. 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 ? Idk this is really annoying I just wish I could fix it , iv already reset the laptop due to the problem which just made it worse 😔, edit: I just reopened device manager and under the network adaptors tab rest of the adaptors are gone only 2 are preset namely Bluetooth device and realtek pcie gbe family controller , this is seriously messed up I cannot do anything on it due to no network someone pls help

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

hello, i already had my advanced settings on AX should i try AC?

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.
