routefix v0.9 [27 Nov 2023] by Dominic
Description
If there is no default route for ip traffic, routefix.sh adds one based on the most recent information from previous leases. One situation where this can be needed is if you turn off wifi (e.g. at end of booting, using https://www.timedicer.co.uk/programs/help/wifi-updown.sh.php, because you have wired connection). For use under GNU/Linux.

Dependencies are shown and while in most cases written and tested on an x86-based Linux server, they should run on a Raspberry Pi, and many can run under Windows using Windows Subsystem for Linux (WSL) or Cygwin. Email me if you have problems or questions, or if you think I could help with a programming requirement.
