Has anyone encountered this?
I have 2.4 and 5 ghz. It'd connect to 5 ghz but data doesn't appear to transfer. Online services like Netflix, Hulu, Play Store don't work.
Everything's fine on 2.4ghz.
I have other devices on 5ghz so no problem there.
Not exactly the same issue, but I initially had trouble connecting to 5Ghz of my Asus router.
After fiddling a while, I disabled Protected Management Frames for 5GHz and everything worked fine. I believe it is a firmware issue of Mi Box given my other Android boxes had no problem even before I disabled the option.
