Hi,
as notaz reported a slow network speed on his Pyra, I thought I'd try it on my testing Pyra myself.
I booted up our system (Linux -pyra 4.19.0-rc6-letux-lpae-pyra #2 SMP PREEMPT Tue Oct 2 21:06:47 CEST 2018 armv7l GNU/Linux) and connected to my WLAN network via command line.
The WLAN router is about 10m away one floor above me, so it has to go through the floor.
I then downloaded a file via wget from my local nginx server.
The result:
2,4GHz: ~2,43MB/s 5GHz: ~4,8MB/s
Ping times are always around 30 - 40ms
So I can't complain about my unit here. That unit has the full metal plate installed as well :)
So either notaz' unit has some issue there, or he used the preinstalled NetworkManager (which might have some features enabled slowing wifi doen, like powersaving) or the system doesn't like his router for some reason.
