Arris SBG8300 Upstream QAM Speeds.
I bought an Arris SBG8300 modem/router in one last June and upgraded to Gigablast. We've had several Cox techs to the house to narrow down the root cause of slow speed and intermittent connectivity i...

I've found wide variability in results using Okla Speedtest. It is heavily dependent on the server you are connecting to. For example, I'm in the Cleveland area and have the 500Mbps plan. Hard-wired into the modem I routinely get between 320-375 Mbps testing speeds against servers only "10 miles" away. However, I always get between 450-480Mbps testing against "Comcast" 88 miles away. Using Cox's speedtest available on Cox's web site when logged into my account, there is variability in results depending on which "Cox server" is selected as well, although the results across servers are consistently really good. Long story short ... which server you are testing against matters.
I'm not discounting you may have legitimate issues with your service. I count myself very lucky to have had consistent and high quality internet service from Cox over the years, especially after following the forum messages for the past several months. If you plan to collect "speed test" data, I recommend you also include results from the speed test on Cox's web site. More than likely these results will only bolster your claims and make it harder for Cox to question the results.
I hope your issue gets resolved soon.
