Slow Wi-Fi
I can get only 20Mb/s Wi-Fi connection. It looks like 802.11n is not activated at all. Am I right?

Max speed is 65 Mb/s for my Jolla. Other devices connected to my wlan router has 150 Mb/s !!! WLAN optimization is still needed.
With a single antenna you can only have a single spatial stream. Most battery powered devices support only 802.11n 20 MHz channels. 1x1:1 antenna configuration, 20 MHz channel bandwidth and short guard inverval gives 72.2 Mbit/s as a theoretical maximum bitrate.

(I'm in germany, that's why it goes up to channel 13) ... Still even when I force my router to 40 MHz the phone connects with 20 (how's that possible at all?). So I guess some software restriction. Any word from Jolla Oy?

I had the same issue. It connects with 40 - 65 Mb/s. But that's slow compared to other devices.
