CM1200 problems?

Question

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.

A screen snip is easier to read.&nbsp;You'd also want to include your cable connections page info to go with the log.&nbsp;&nbsp;I'd also test directly connected to the modem without using a router. Because the router can cause lag as well.&nbsp;

both the logs and cable connections page show errors/problems with the line.&nbsp;I'd remove any spliters, amplifiers, or attenuators from the line. Also check the line for any damange, kinks, extended runs, loose/cheap/bad/old connectors.&nbsp;If none of that helps, contact your isp to check the line.&nbsp;

Be sure your using good quality RG6 coax cable up to the modem.&nbsp;
