Topic basically says it all. My Linksys wgr614v6 will begin to climb up steadily pingwise (over the course of some hours,)until it reaches the point of absurdity- last night it hit 2680. The only fix that I have been able to find is to reupload the firmware, (the latest one), which return the ping back down to reasonable levels. After doing an upload, my previous ping returned to just over 100. Not too long after, it will begin to climb again. Between the resetting of my ping to normal and it become absurdly high, I adjust no settings or the like. Any idea what could be causing this?

Thanks in advance.
