Would you comment on what router and software you are using, how difficult it is to maintain, and any surprises you have had using it (things you depend on breaking).
An excellent guide: https://killtacknine.com/building-an-ubuntu-16-04-router-par...
Up for months, incredible speed, no maintenance, except to add new domains to block when they prove to be spyware. Twitter may be next on the list since it is of declining use to me.
I'll add that I'm by no means a linux whiz, but learned a lot by doing this project.
Biggest issue is explaining to guests why they can't access facebook.
Another bene is you no longer have the planned obsolescence of consumer grade equipment. I fully expect this thing to last a decade, and "firmware" is automatically updated via linux.
No surprises, the Omnia updates itself and reboots automatically (you get an email warning of you want to intervene) and everything 'just works'.
