Currently I'm using a Motorola SB6120 modem and a Cisco/Linksys WRT120N router streaming movies to my Samsung TV. My issue is this, when I stream movies from my computer to my TV I get a loading prompt after watching the movie for a few seconds when the movie exceeds ~15gb. If the movie is ~14gb or smaller I don't get the loading message on the TV so I assume my router is having a difficult time streaming the larger movies. Would a different router able to send data more quickly help out in this situation? If so, are there any recommendations on the brand? My tv is about 30 feet from the router and I have full signal from the TV to the router so it's not the lack of wifi signal causing the loading prompts.
Any help is appreciated and thanks in advance.
