router causing me to DC?

I have a Netgear N600 wireless dual band router which i am plugged directly into and I get 90k a lot at random times, but when I plug in my older Netgear N150 wireless router I don't experience lag, freezes, or DCs at all. Anyone have any Idea what is going on and know how to fix this?

Maybe see if there is a firmware update for that new router.

same issue, same router. completely up to date. new router is on it's way now, gave up on it cause of too many problems.
