Recently Announced Internet Speed "Boost" Not Working

1) Yesterday, I received an email from Cox stating that I have received a speed boost on my Cox High Speed Internet Preferred service from 100 Mbps to 150 Mbps. 2) The email stated that I needed to reboot my cable modem in order to activate the new speed boost. 3) I have repeatedly rebooted my cable modem over the past 24 hours, both by unplugging and re-plugging in the device, and by using the online cable modem reset process on the Cox website. 4) I have also disconnected and reconnected every Ethernet cable running to and from my cable modem, router and computer. 5) My cable modem is an ARRIS Model SB6183, which does meet the DOCSIS 3.0 requirement necessary to receive the faster internet speed service. 6) My router is TP-LINK Model AC1750 Wireless Dual Band Gigabit Router connected to my computer via a Realtek PCI GBE Family Controller Gigabit Ethernet adapter, which is more than adequate to handle a 150 Mbps internet connection. Given all of that, my connection speed remains exactly what it was prior to my supposed speed boost based upon tests I have run on Cox's website, and the OOKLA Speedtest website, which is usually in the range of 90-95 Mbps, which I test on at least a weekly basis. In other words, I have received no speed boost whatsoever. Is anyone else experiencing a similar result?

  • This may not apply to your situation, but if anybody is using QOS on their router, you can still use it but there is a step in that setup (at least on Netgear router) that is critical...Netgear has a step under QOS setup where you have to run a speed test so it knows how to adjust its settings accordingly. If your speed from your ISP is increased later on, you must run that test again. When I did that, I got the 50 meg boost in my own speed test run outside of the router...just wanted to put that out there for consumption.
