The above link is for a relatively new driver for the stock WiFi card shipped in the Cubei9. My WiFi speeds were AWEFUL to say the least. When I mean aweful, like .5Mbps from 3 feet away from my expensive linksys wrt1900acs router! I simply installed this driver linked above (dated ver. 3-7-17) and eureka! I am now getting 20mbps through 2 rooms without any hassle. I strongly suggest to all cube owners to update to this newest Realtek driver! I hope this helps. If, so, comment. If not, ¯\_(ツ)_/¯. This tablet is now my official everyday driver.
