I don't know if the good post but I've got WIFI problem on tablet Polaroid MID 9748 Android 4.2.2 kernel 3.0.36, CPU RK3188
Tell me if I've been moderated.
For example, when I switch from an application to the other as my browser to google play, I've to switch my tablet in plane mode in and out for refreshing the WIFI connection.
I don't know where this problem is coming from because I'dont have any problem for watching streaming also the wifi card should work fine.
Could be MTU problem? How to check?
Thank for advise
