Set a knob's WiFi over its cable

Without a phone or the knob's VFOKnob hotspot: from your browser and the knob's USB-C cable, see the networks it knows and the ones it hears, and put it on yours. Nothing is erased — the network joins the ones it knows, as on the phone's page.

What it takes

Chrome or Edge on a desktop or laptop — Windows, macOS, Linux or ChromeOS. Other browsers, and phones, have no Web Serial to reach the knob with.
A USB-C data cable, the plug the right way round: the knob shows as USB JTAG/serial debug unit. Shown as USB Serial, the cable reaches its second chip: turn the plug over.
The knob on firmware 1.20.2 or newer — any of its firmwares but AetherSDR's. One older than 1.20.2 needs the update first: update its setup firmware over the cable, its settings kept.
On Linux, your user in the serial ports' group — dialout on Debian, Ubuntu and Fedora, uucp on Arch — then log out and in again.

Good to know

The password goes from this page to the knob over the cable, and nowhere else: not to vfoknob.com, and never back out of the knob — not on its cable, not into its log.
The knob keeps up to four networks and joins whichever is in reach. To remove one, or give one a new password, use its configuration page, under WiFi.
The AetherSDR firmware has no console on its cable: its USB-C is a network to the computer, with the knob at 10.55.42.1. Its WiFi is set on its own configuration page, http://10.55.42.1/, with the cable in.

A knob that will not join from here, though the network and its password are right? Open the Log above and report a problem, with the log, the router's security and its channel.
