VERY SLOW UPLOAD SPEEDS, download is fine.

Zurq...wealth of info...now my numbers of -8.9 to -13.8 and 48.4 to 50.4 are outside the ranges you posted, but you implied my power levels are running well....really?  Do you know if there are better indicators on the Netgear main panel...mine said Good.  My c6900 is my modem/router purchase.  I don't understand 'bridge mode', and yes, it seems like a Cox prob since it only started recently down to about 4-6 upload.  Also, 'qos' I'll take a look again in forum, seem to have seen this notation.

I will also take a look at task manager...that should be fun.  As I said, pingplotter to the hop#6 to cox.com from my ip definitely shows %Ploss...If you have pingplotter or WinMPR, check the hops to cox.com.  Also in the Cox speed test, try to go to OC server...you may be on the other side of the country so your numbers could be anything....especially if you are getting in 5's for upload.

I did a  cmd ping -n 20 cox,com and got Zero %packet loss, but pinplotter, which checked the hops did find #6 loosing 30%...  Curious

Update...did a taskmanager view of performance/ethernet and then engaged the cox speed test to my OC area...task mgr gave high of 248 while speed did 220+...but the upload had taskmgr 11.2 max, and cox speed test had around 6...good tool Zurq!
