As MJ says.
Getting a recalcitrant network link to work is a strange task. You try everything, and nothing works. Then, all of a sudden, there it is. My VPN from here to Essex did that on Wednesday.
My router has a printer USB socket on it, which I thought was a spiffing idea. Then I found it's "one direction only" - the printer can't report back when it's out of toner, or paper, or whatever. I went back to printer on desktop, shared over network.
