Not sure! Many of these kids' laptops are meant for travel and to be used with a roaming WIFI signal or a hotspot. If the computer has the capability, it might be improved through a modem with an ethernet cable. Most of the computers for kids don’t have the ordinary Mac and Windows OS, therefore it’s dodgy as to what can be done with it.
Look at the amount of GHBs and GHZs it offers, which is a telltale sign of its performance and the output of CPUs that can give better resolution and buffering speeds for something like streaming.
