sry, I didnt know where this belonged. My parents were trying to stream netflix on their tablet from their bedroom (their modem and router in the livingroom), but they were saying the connection was laggy, it kept buffering. I came over with my Galaxy Note 8.0, connected to their wifi, downloaded and opened the "Wifi Analyzer" app, started next to the router and walked to their bedroom. By the time I stopped the signal was at about -72 dBm. Im wondering if there is a minimum that a signal strength has to be in order to stream smoothly. I know the higher the strength the better, that goes without saying. But im looking at possibly either having to hardwire to the bedroom, setup a repeater/booster router, or simply moving the router. Im hoping I can just do the later, but either way, more network cable will be required.
