Jul 20, 2026, 5:59 AMOne gripe with the Argon One Up is WiFi performance seems to be weak. Reading the documentation, it appears the CM5 defaults to using a PCB-trace antenna which lives behind a massive heatsink inside the base of the laptop.
Not a recipe for success on microwave bands.
https://www.jeffgeerling.com/blog/2022/enable-external-antenna-connector-on-raspberry-pi-compute-module-45/ describes how to switch it to the "external" antenna, which is presumably better placed.
Doing this, it seems to receive a lot better.
