Hey CG. I wanted to add a bit more info on the Wifi odyssey. I ordered and tested several different post-style antenna some of which boasted some impressive (but unlikely dB gains). The issue didn’t change. Wifi connectivity and performance was lethargic with these antenna. But grabbing the antenna seemed like the miracle fix. I also tried a stock Espressif dev board (ESP32S3 USB/OTG board). It just used a compact board/wafer antenna (soldered onto the PCB). And it seemed to work better. But when moved it to another room in the house, I got the same connectivity/performance issues. And once again, this was resolved by touching the antenna. So it’s not the XIAO board. I just purchase a TinySA Ultra Spectrum Analyzer to see if I can gain some insight into this sporadic issue. Till then, don’t try to adjust the horizontal or vertical (Twilight Zone)
