Hello list,
I'm running Debian 9, and I'm having issues with WiFi being occasionally
unstable. It will run just fine for a while, but sometimes it will
suddenly fail.
/etc/network/interfaces:
> allow-hotplug wlo1
> iface wlo1 inet manual
> wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf
>
> # default wireless interface
> iface default inet dhcp
> openvpn-client chaos
>
> # home
> iface home inet static
> address 192.168.0.2/24
> gateway 192.168.0.1
> openvpn-client chaos
openvpn-client is just a modified version of
/etc/network/if-up.d/openvpn that uses openvpn-client@* units instead of
openvpn@*.
/etc/wpa_supplicant/wpa_supplicant.conf:
> ctrl_interface=DIR=/run/wpa_supplicant GROUP=netdev
> country=KR
then the network blocks, like so:
> network={
> ssid="<snip>"
> psk="<snip>"
> id_str="home"
> }
