Desconexiones aleatorias de wifi (buster-lxde-wicd-pavilion dv6-Atheros AR9285)

Buenas, mi problema son desconexiones constantes.

Mi tarjeta de red es la Atheros AR9285.

He comprobado de todo, uso el gestor de red Wicd.

pego aquí lo que devuelven algunos comandos:

He buscado y mirado bastante info, he probado varias cosas, pero sigo igual.

A parte de este problema, tengo uno con navegadores que aparentemente no tiene nada que ver con la wifi, pero ya no se que pensar.

El problema con los navegadores lo detallo en este hilo:
/foro/problema-con-firefox-esr-y-con-opera-en-buster-activo

a ver si alguien me puede echar una mano.

Un saludo y gracias de antemano.
