Wifi low performance - SOLVED
Had the device on 200/200 fiber connection and measured full speed on both cabled and wifi connected Win10 devices (Ookla speed test) .
Upgraded my ISP speed to 500/500 and now have full speed cabled but approx half of that on Wi-Fi.
Funny thing is that my pc states 433 for the physical connection but the speed test shows half regardless of distance to the device.
Rebooted several times between tweaking settings to no avail, now back to original (no Smart connect)
On the brink of getting angry with the AX6000 I checked my laptop (Lenovo) wi-fi net-card:
Realtek 8821ce wireless lan 802.11ac was not designed for this speed!
As a heads up - do check both ends of your communication before blaming any ;)
The solution may be to get a wi-fi card as USB dongle.
Not too expensive, just make sure you have a free USB 3.0 port as USB 2.0 will not cope with the fastest dongles.
