[AZ] Poor & inconsistent down speeds in Chandler, AZ (85248) I've been experiencing some speed issues with tests reporting an average between 5-10 mbps down and 15-20 mbps up since moving into a new home in south Chandler (85248).
Replaced wireless router (thought my wi-fi just sucked)
Upgraded to a DOCSIS 3 modem
Tested speeds plugged directly into modem from my Mac laptop and found same issues
Tested throughout the day and found that one in five tests during the morning to early afternoon will reach 25-30 mbps down, but the very next test will be right back around 5-10 mbps. (using speedtest.net, scottsdale server)
I'm not sure what to do - an initial call to COX was useless, they just wanted me to clear adware and spyware (which I didn't have) and at the time I was banking on a new modem fixing it. Do I need to have a tech come out? What will they possibly do, my downstream, signal to noise and upstream specs seem great? Would love some input!
Modem: Cisco DPC3010

Cox line from street grounded and connected directly to prewired coax that connects directly to modem
Line quality tests always show 0% loss, average latency 72ms
first i would switch speed test servers as the ones in AZ are not very good, try testing Los Angeles. also if you have any programs set to check for auto updates turn them off, but beyound that you may need a tech.
Thanks m8trix, per your advice I will stop using the AZ speedtest servers. I just found a link on this site to the official COX speedtest and am going to use that for now since I have noticed it reports my speeds more consistently and keeps a log.
Something I also didnt really mention earlier is that the variance I see when performing any speed test is quite large. testmy.net shows a 70 percent variance and the official COX speedtest shows dramatic peaks and valleys on the graph during the test, and streaming video on netflix will go from HD to buffering and back to HD. Could I be getting some weird interference? Could one of my neighbors have an ultimate package and be sucking up all the bandwidth? (does it work like that)?
Thanks to anyone who can provide some insight.

We have a Ultra business line at our residence and we've had 2 or 3 occasions when we had the Cox tech onsite. I stay close to the tech in order to learn about the service and the method used to troubleshoot. Here are some of the examples of things the technician performed; frequency tuning with filters, double checking the coax connection at the street box with improving the ground wire contact, improving the ground contact at the outside wall of the house, and giving a a lot of attention to the actual type and condition of the coax cable. With the higher speed data service the techs were really focusing effort on the wires and connections from the street to the modem. FWIW
