Slow Wi-Fi
asked 2014-03-21 00:28:22 +0200
I can get only 20Mb/s Wi-Fi connection. It looks like 802.11n is not activated at all. Am I right?

Good news!!
After latest update (1.0.5.16) I'm getting pretty good speeds, around 50Mbps. I'd consider this fixed as 2.4GHz WLAN is a bit glacial at high speeds..
EDIT:
Hotspot is still running only in 802.11b/g.

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.
