In the morning, Jay went to the rec centre in Burnaby.
I ordered a TP-Link Deco X60 router with one mesh satellite. That prompted me to play with my current wifi network again. I am as close to stability as I can get until after Amazon brings my hardware on Friday. My SSID had been WINDTALKER for as long as I can remember. I remember setting it to that back when we had ADSL through the phone company. From today, my 5 GHz band is called ForbiddenPlanet. And as my new router will have bound 2.4 and 5 GHz bands, I'll use that going forward.
All my Google Home speakers and displays should seamlessly accept the new setup. However, most devices are still on the old SSID and that means I will have to reset all the bulbs and switches to match the new wifi name and password.
