Fidelity.

For no reason I'm capable of understanding, starting sometime yesterday, my iPhone and iPad stopped connecting to my home wifi. The network was there, the devices acknowledged it, and my desktop was always able to tap into it through the relevant connecting device. The desktop's too old to have inbuilt wifi capabilities, but the iPhone and iPad were new enough they've got it, except it wasn't in them. They kept saying the password was wrong. I checked on the wifi router provided by the phone and internet company and typed it in, several times, and neither device acknowledged it as correct. I tried the trick of having the devices forget about the network before trying to reconnect, and it didn't work.

Resetting the route managed it, somehow. I'd be better able to understand what happened if the desktop also didn't get it for a while, but it did, so I have to wonder where things got messed up. Because there was a problem that got fixed, and it wasn't a problem for everything.
