Raspberry Pi 3 loosing wifi - busy status

[Nachteule]

Uh, looks not nice. Seems driver is being confused. In this case -a option does not help

Try this script on next failure:

Code:

#!/bin/bash

ROUTERIP="192.168.1.10"

if ! ping -c3 $ROUTERIP > /dev/null 2&>1; then
    echo "Restart WLAN"
    /sbin/ifdown --force wlan0
    /usr/bin/killall wpa_supplicant
    /sbin/rmmod brcmfmac
    /sbin/modprobe brcmfmac
    sleep 5
    /sbin/ifup -a
fi

This reloads module brcmfmac. Last command (/sbin/ifup -a is optional and should not be necessary)
