You many need a router booster if the router is a distance from the tvs. Also the lowest version of Roku is very slow to stream and keeps buffering. I upgraded to a better version and it's so much better. Also the quality of the HDMI cables make a big difference too. You can go into setting on Roku and select the lowest quality for old tvs. That won't make the picture bad just speed up the streaming. If you google Roku tips you get a lot of information.
