I've had this modem and router setup going for a while now. Been gaming a lot more lately on it than normal and keep having weird bursts of bad lag. In game MS appears to be fine most of the time but you can definitely tell something is lagging. I'm not entirely sure where to start but logs on my modem bring up errors I'm not too familiar with. If anyone might point me in the right direction or make sense out of these that would be great.
