A few weeks I noticed my speeds had dipped and were capping out 30-35/mbps. Testing from a laptop directly into the modem. Reset modem and speed is back to 500 for about 90 seconds then goes back down. Replaced the ethernet cable and coax - nothing.Called Cox - no help. Replaced modem with a brand new Cox modem. Full speed lasted about 5 mins before going back down to 30. Please help Cox. Your online tech support is terrible.

I saw a Cox truck with a lift driving around my neighborhood yesterday. Checked my speeds and they are back up! Checked again today and still getting a solid 500+. I'm hesitantly gonna say this problem is solved.The issue was something going on on poles delivering service. Glad it wasn't anything on my end. Hope this may help anyone else dealing with slow speeds. Cheers all.

500 plan speeds drop to 30mbps

File an FCC complaint. They use support to just pressure people to purchasing more equipment and pay their exorbitant motor rental fees and support fees which should be included. If the drop yo your house is more than 10 years old it often needs replacement if exposed to the weather and the techs don't want to do it so they gasslight and blame your hardware. Also They have a monopoly. They only care about profits regulations and fines. File with the FCC. They will have someone with actual authority resolve your issue or they will get fines.

  You are inaccurate. I have an RG6 cable from the box to my house that was installed in 1998. The ONLY reason it would need to be replaced is if water got inside. As long as your home connector has the proper watertight insulation on it, you should be good. ALL the center wire carries is an RF signal, much like a radio antenna.
  When mine needed to be replaced, it took Miss Utility 40 days to come out and mark the ground, (Important because out electric grid is underground here), and within the week, Cox was out and replacing the run. Spreading misinformation only makes you look sad.

    Ehh, 10 years is about right for coax replacement, atleast for any cable line ran along the outside of the house exposed to the sun and elements. The line will dryrot and crack and you'll start to notice poor service specially when/after it rains and water soaks into the line, until it dries out. But yea, 10-15 years sounds about right with us starting to see service issues every time it rains starting about a month ago and we had ours re-ran about 10-12 years back.

Try using a different ethernet cable, and reboot your laptop into "Safe mode with networking", and run the test. If you are seeing the same issue, then it's indeed something with Cox. If the speeds increase dramatically, and stay that way, you have a piece of software on the laptop running in the background that is slowing it down.
My test on an Alienware R16 with everything running right and no background software is - https://www.speedtest.net/result/16448515900
That's a Netgear CM 2000 and a Netgear RAXE300 router. Speed being paid for is 500 down and 50 up.

Another common reason is your local node has to manu people on it and during oeek hours your Internet goes to crap. It is e
Very expensive to expand and Especially in rural areas don't expect rapid growth so often won't replace it until it is long past due. Seen it happen repeatedly.

  My local node is on Dark Fiber, I seriously doubt there are enough people hooked up using 2gb service to even put a dent in the capacity of that fiber.

I have same thing happening with sb8200, in October it started dropping speed to 30 mbps. This happens about once a week or a month, cox tech was out, checked the line and said the line is good and started recommending that I should use their equipment and blah blah blah. Having a second tech coming out if they dont fix it, i will file a complaint.

  Tech came and replaced the phone/cable box on the side of my house and replaced some old coax connections. No change - 500 when the modem resets then back down to 30 after a minute or so. He went up the pole and said signal strength there is bad and outside plant dept needs to check it out.
  Once they come out I'll give you another update.

  Whatever happened in this guys neighborhood, please make it happen in mine, I pay for 500mb and have unlimited data but only get around 20mb multiple restarts will only most of the time show speeds around 200-250mb and rarely close to/slightly above 500mb but they immediately drop back down to around 20 after the test.

I am having this exact issue. 500mbps slowing down to exactly 30mbps. Issue persists even after replacing router and a technician visit who also replaced old connectors in and around my unit. Any idea how I can go about getting Cox to investigate the service coming to my apartment complex?

  Call in to tech support, and request escalation to CAG. They are far more knowledgeable and will be able to either assist, or get the right person on the fix for you.
