I just got this new DIR 880L, had the 810L before and had qos setup on it, im hoping to get help again setting it up for this router, reason we switched is because there are multiple devices sharing the wifi, 3-4 cell phones, laptop, xb360, smart tv. And this router should be more powerful.But im the only one who plays lag sensitive multiplayer games, & when multiple ppl are on it can affect my connection.
