For once, not DNS: Huawei Modem ARP spoofing

A couple of days ago I noticed my Ring Chime was disconnected in the Ring app. After a couple of years happily connected it was time to fulfil the ultimate purpose of both software and hardware: annoy humans.

I went through the reconnection process a couple of times to no luck. I called Ring support, who took me through the same process a couple of times to the same result. But one step in their process yielded an unusual result: if I set up a WiFi hotspot on my phone, the Chime would connect to it!

But when renaming my home WiFi network to have the same name and password as the hospot, the Chime still can't connect.
