      The motorboating sound you hear in the lab (at 27:45) is definitely the beacon signal of your Wi-Fi router.

      Is it a trick of the light, or are there some concentric rings and trace discoloration on the board around the capacitor to the left and up above the chip around 24:20?

      My mother (trained physicist – retired, natural born troublemaker) had an interesting theory:

      Do you think the person who sent this device in had deliberately changed the resistor to the wrong value as an imaginative way of breaking it, in the hope you would spend hours futilely

      trying & failing to troubleshoot it using the usual techniques?

      It definitely looked like it had been resoldered at some point… [*Evil Chuckle*]
