Internet speeds inconsistent and seemingly slower - anyone else having these problems?

During the last couple of weeks, internet speed in the Orange County Ca. area of Cox has been suffering from latency and inconsistent speed, at least at our place.

My modem has regularly returned Speedtest ratings of up to 200mb, but after a Cox tech came out and crimped a couple of connectors in our box, highest I'm getting is 130mb down.  Up speeds of 10mb don't seem to have changed.  Latency is kinda lousy, but that could be the modem.

Anyone else suffering in Cox areas the last few weeks?
