salu2
se que muchos lo sabreis pero he visto reportes igual en la red ....quizas os pueda pasar al igual que a mi
yo por ejemplo tengo una intel vieja incorporada cuando le meto 2 interfaces a wifislax no se que pasa pero a veces me desabilita la deteccion de algunos canales muestro ejemplo y solucion (nota a veces tengo meter el comando 2 veces para que surga efecto)
saber que interfaz es phy
wifislax64 ~ # iw dev
phy#1
Interface wlan1
ifindex 4
wdev 0x100000001
addr 08:86:3b:XX:XX:XX
ssid MIWIFI_XXXX
type managed
channel 6 (2437 MHz), width: 20 MHz, center1: 2437 MHz
phy#0
Interface wlan0
ifindex 3
wdev 0x1
addr 00:1b:77:XX:XX:xx
type managed
channel 140 (5700 MHz), width: 20 MHz (no HT), center1: 5700 MHz
ver canales altos si estan disabled he puesto A 30 pero para todos canales A 52

se ven canales desabilitados a partir de 100
y el comando puede haibiltar de nuevo canales altos
sudo iw reg set EU
