[Discuss] printer issue

[John Abreau]

I generally recommend minimizing the amount of trust you give to your ISP.
I've switched between different ISPs over the years, and if the ISP insists
on providing its own wifi router, I would connect only one device to that
router: my own personal wifi router.

My internal home network is always under my personal administrative
control, and I only use the ISP to transport bits back and forth between my
private network and the public Internet.
