Couple of days ago, wifi connectivity got really bad. There are two scenarios. First, it doesn't want to connect to wifi even though all my other devices are connected to the same wifi/router, and under wifi name stands 'obtaining IP address' or 'avoided poor network connection'... Other case is, somehow it wants to connect but the speed of internet is just terrible! So very slow... So pls help, V20 is a great device and I hope I can have this problem fixed! Tnx
