I am currently running the early access OS 6 on a Raspberry Pi 4 with the Argon One M.2 case, and booting from the M.2 SSD. When I have the SSD connected to either USB 3 port of the Pi, then I cannot connect to any wifi network, though it does still list the network. It simply times out and fails to connect. However if I switch it over to either of the USB 2 ports then all works perfectly.
I also tried booting into Raspberry OS with the same setup (from the M.2 SSD). That works fine.
I have seen discussions on other websites about known issues with the USB 3 standard and wifi, but I do not think this is the problem here, because Raspberry OS works.
Could this be that Elementary OS is drawing more power, so maybe I need a larger power adapter? I have no other clues as to what is causing this issue.
