Yesterday I was disconnected from the internet.
The help line couldn’t help. But Mr Strange Land was able to talk me through setting up a workaround in about five minutes.
For reasons, he wasn’t able to work on it last night (singing lesson, and then a pressing engagement with me and episodes 3.9 and 3.10 of Babylon 5).
But this evening, he spent some time diagnosing the problem, and reloading and updating software, and clicking various buttons, in that mysterious way that adepts have. And behold, I have internet access again.
He is very clever.
