If you're talking about buffering in regards to the cox website and webmail there is nothing you can do. This has been a problem for many people over the last month. Cox won't acknowledge as anything other than a problem on our end and keeps suggesting the same fixes that don't work over and over.
They have to figure out what the problem is on their end.
Becky, when I sign into my cox email account (idm.east.cox.net) it take me to the menu and I select webmail: myaccount.cox.net/internetttools/home.cox... and that's when the buffering starts.. it just stays on the page I selected "webmail" then after getting out and going back in a couple attempts it eventually pulls up my emails... and once my emails pull up I go out and back in a lot quicker... doesn't make sense...and happens every day..
OP, you may have a signal issue at your house which is causing packet loss and in turn latency and buffering issues. What is your upstream levels and downstream levels from 192.168.100.1? I'm almost certain you have a RF signal issue at your home.
