djones connect your Dell T7500 with integrated Broadcom NetXtreme gigabit ethernet card directly to your Netgear CM1000 cable modem with a cat cable. If you have a firewall or antivirus installed on your computer temporarily disable them. Don't even think about using your Netgear Nighthawk X4S router or switch. Completely remove those 2 items from the picture. Do a another speed test with that setup. The test will show a faster speed than 425. Report back with new download and upload speeds. It is essential you provide the new speeds you get from the test.
Thanks for all the replies. What I meant to say in my second post was I hooked my computer directly to the modem and got the same speeds. I am having to reply on my phone because I can't keep my modem online long enough to send a post. I don't mean to be disrespectful, but I know what I am doing when it comes to networking. It's not my modem, router, switch, or system. I can team dual cards and transfer well over a gig on my network. I do it all the time. The router is more than capable of getting the speed I should. But the first thing I always do when having issues is go directly from modem to computer. Even with the techs test modem, no difference.
I've had numerous techs come out and finally had a field technical specialist admit to me that there is a problem that myself and about a thousand other people in my area are experiencing. At this time there is not a solution. Downgraded to ultimate service and now I have better speeds. My issue is Cox sold me a service they couldn't deliver and admitted that it is a problem they were aware of but don't know how to resolve. Anyway I was credited for crappy service and all is good now. I would still like to have faster speeds, but I refuse to pay for a service that can't be delivered.
