Well, I can tell you which dual-boot tablet from China does NOT have spectacular WiFi….the Chuwi Hi8 Pro Dual. I got one last week and its Wifi performance is nothing to write home about. The screenshots below were taken using the Network Signal Info app, while I was sitting in my living room on the 1st floor. My router is about 30′ away in the opposite corner of the house, and 10′ down in the basesement.
Can you guys report what was the wifi NIC (device) that those tablets were using? Then we can compare them and perhaps find out why they had poor performance.
@ag, probably most important for YOU to know is if the NIC is a separate/discrete card (I think it’s called an M.2 PCI card?) versus soldered onto the motherboard. That way it is changeable. I believe the vast majority have them soldered on.
