Was poking around in my router setting and decided to try disabling all "Basic Rates B" and "Basic Rates A/G" except 54Mbps (it don't have newer n or ac or 5GHz). First thing I did was running ookla speed test on an android phone, it went well and showed about 40Mbps. After a while I was reading mail and smelled something was up, so ran speed test on the SF phone. To my surprise it showed puny 2Mbps. To investigation! (not really, just more poking):

54Mbps and 48Mbps enabled: android - 40ish, SF - 4ish (Mbps)

54Mbps, 48Mbps and 36Mbps enabled: android - 40ish, SF - 30ish (Mbps)

--phones at about the same distance from AP, tests ran a few times each change on both phones, SF tested the same with native browser and firefox--

Is it a bug, hardware limitation or a feature?

What vendor image are you using? v17b of the Sony vendor image has a dilemma with WLAN visibility.

SW_binaries_for_Xperia_Android_8.1.6.4_r1_v17B_nile. Wi-fi works but slow. I've noticed it's trying to use 72.2Mbps-20MHz/1S/SGI from n standard for some reason.

Yup, when flashing Xperias to use SFOS, that same behaviour is mentioned by Jolla, suggesting to use the v16 because of its poor Wifi permormance.

I'd reflash and use the 16 as recommended.
