El problema
El ícono de wifi desaparece repentinamente, dejándome sin acceso a Internet. Esto ha sucedido aproximadamente 3 veces en la última semana y no parece ser provocado por nada de lo que hago. El último (el que estoy copiando los dmesgresultados) se produjo mientras trabajaba en emacs (tenía un par de pestañas inactivas abiertas en Firefox).
Soluciones intentadas
visitéesta preguntapero mi caso no está relacionado con vmware y la solución en la respuesta no funcionó para mí ( nmcli network on, ni siquiera cuando estaba precedida por nmcli network off).
Inmediatamente después del último caso que ejecuté dmesg -HTy vi algunos errores asociados iwlwifi, así que fui aesta preguntae intenté cargar el controlador, sin éxito.
yo también miréesta pregunta, pero mi firmware parece estar actualizado:
stat -c %y /var/lib/apt/periodic/update-success-stamp
2021-10-09 11:47:13.854452373 -0500
Lo único que me ha funcionado es reiniciar, lleva mucho tiempo y es realmente problemático.
Preguntando
¿Qué debo hacer para evitar este tipo de problema?
Contexto

Como sugirió amablemente @chili555, se trataba de un problema de hardware.
Simplemente quité la tarjeta, la volví a colocar y apreté el tornillo, y el problema desapareció durante 48 horas completas.
