For context, I am currently using a CM1000v2 modem hooked up to a nighthawk MR60, which is connected to two MS60 satellites spread intermittently throughout my house.
I currently have gigabit internet through Cox, but for the past week, my download speed has been no higher than 30 Mbps consistently. I've tried resetting the modem and the router multiple times to no avail. I then thought that this may be an issue with the satellite system, as I've heard they can be finnicky. So I took my laptop and ran an ethernet directly from the router, only to find that the speeds were no different; ridiculously slow. At this point, I called my ISP's help line, and after slogging through them suggesting that my issue is that my CM1000 is too old, which I'm pretty sure isn't the case (?), they said that my house was receiving the correct download and upload values. Now I did make the mistake of not asking whether or not that rules out any issues with my coax cable, and if it does, that would at the very least narrow things down to my router and/or modem.
Power down, pull the cord, from both the modem and the MR router and disconnect the Ethernet cord between the two.
Start with your laptop computer also powered down. Power up the modem and let it completely boot. One of the last indicators to illuminate should be internet access. Connect an Ethernet cable from your modem to your laptop and boot up the laptop. Use the Ookla stand alone application for testing throughput. This should give you a reference for what is coming out of your modem. Do not depend on a web browser and a web testing site.
The CM1000v2 modem is a DOCSIS 3.1 modem capable of supplying 1 Gbps throughput. Make sure your modem is on the official list of COX supported customer owned modems. If not, it means COX no longer has the proper firmware to support the modem on their network.
Unless the COX web site is out of date, your CM1000v2 is on their list of customer owned modems certified for use on their system. Scroll down to the 1 Gbps or lower section.
