Hi, my experience is that this tablet does not work in dual band networks (2.4/5GHz) since switching from one to another frequency causes virtual credentials lost (network password) and reports that your settings don’t match. I’ve performed many tests and this is the reason – switching from one frequency to another in modern WiFi networks. Can not confirm that reverting from WiFi6 (802.11ax) to WiFi5 (802.11ac) solves this, but for sure it might help since WiFi5 is 5 GHz technology only and there is no reverting to 2.4Ghz in case of low signals. 5GHz frequency has much higher attenuation than 2.4GHz, so it might not work for you on some distant spots to your WiFi router/modem.
For tablet use inside your home with administrative access to the router settings, you can split 2.4Ghz and 5GHz to separate networks, e.g. one with SSID myssid24 and the other myssid5 (set Band steering setting to OFF and configure each frequency separately). Then decide, which devices at your home will be registered to one or to both networks. Alldocube tablet MUST be associated to only ONE of them (I strongly suggest 2.4GHz since the WiFi part of this tablet has quite bad WiFi radio performance). Then it will work.
But when you move to other location with dual band WiFi, probably also to WiFi4 (802.11n, dual band) e.g. at your workplace, school etc. then better FORGET to use this tablet. It will also “destroy” corporate networks associations with certificates, which can not be reconfigured easily on your tablet.
A summary: this tablet forces you to lower the quality of your home network and makes it impossible to be used on modern dual frequency networks.
Now you know. Geekbuying offered me a possibility to return the tablet and receive a refund, but I will rather use it for smashing flies around the apartment or use it as a kitchen cutting utensil. 🙂
Will never again think of buying an Alldocube device (very bad support, no OTA updates, no “what’s new” description for firmwares where even dates and versions do not match). So sorry to all of you, my “brothers in arms”..
