Unable to reconnect

Network WiFi
1

I have IPfire on a laptop. It takes WIFI hotspot in from phone, and Ethernet cable out to my desktop.

Works nice, but when I leave with my phone and come back, the desktop cannot connect to internet. “Save and refresh” from webgui, or rebooting the laptop do reset the internet.

Where to look, what to change, so the recovery is automatic when my phone hotspot comes back in range of the laptop?

I added

scan_interval=15
bgscan=“simple:30:-70:5”

to /etc/wpa_supplicant.conf

(Didn’t work)

Adding

#!/bin/sh
TARGET=“1.1.1.1”
IFACE=“red0”

if ! ping -c2 $TARGET >/dev/null 2>&1; then
logger “RED watchdog: no internet, restarting RED”
/etc/init.d/network stop red
sleep 5
/etc/init.d/network start red
fi

To

/etc/fcron.minutely/red-watchdog

Seem to have done the job

Restarting unbound instead of red may be faster.

Thanks for this little script. I’m testing solutions for a failover with fixed IPs, fixed DNS-Server and without dhcp.

Unbound seems to reconnect automatically after about 5-10 minutes without restarting red, I presume.

I never searched for the timeouts.
