I also got my chuwi hi12 this week. I already did the bios update and reinstalled windows and did a factory reset of android and i put ram to 1600mhz. Everything works finde so far except WiFi speed in windows. It soooo slow… 300kbits maximum.
It shouldn’t be the driver as you will be using the same driver as others. Mine is running at 10 Mbps or max for my current router. Try closer to your router to see if it’s signal strength related.
it is getting better when i stand 1m away from ther router. but thats not an option. it works fine in android even 10m away from the router. but as soon as i switch to windows the bandwith is at 200kbits.
so there is definetly a difference how android handles the wifi and how windows does.
btw: both system show full signal strength!
Which is the lässt wifi driver and were do i get it from? Is it save to update this driver via Windows update?
