So the region setup for WiFi driver it´s not coming from the kernel or resource.img but from system.img; so in Ugoos LP, the region for 5 Ghz band is not USA, it´s any other for that reason the R89 cannot see 5Ghz AC channels from 100-112 & 132-144. The 2.4 Ghz & 5 Ghz wifi region can be easily changed by the users in Windows system thru driver´s properties, it´s not the same in Android that if the developer/rom cooker does not consider this aspect the user can not access this property. Wasser v3.0.3 & 3.0.4a do not have this problem, in 5 GHZ band the Wifi can see all channels and the signal it´s very strong.
The attached file (from dd-wrt forum) shows in dark-black color the 5 Ghz active channels by regions worldwide; setting a very restricted region into the driver produce these problems.
