Please read this and save time for packet loss and slow speed

Hi everyone ,

I would like to make your life easier so you don’t have to post. I am an IT network professional. The reason your internet is slow and you are not getting full speed and you have packet loss is because cox internet lines are old and outdated . They are not meant to handle this many people working from home and not outside. The lines are over saturated and can not handle the workload. Nothing cox tells you is going to fix this problem so please don’t try. The only thing cox can do to fix this is replace your outside lan node. Which they most likely won’t do because it’s extremely expensive. Upgrading to Gigablast will not fix your problem....getting a new modem will not fix your problem... having a tech come out will not fix your problem... resetting your router will not fix your problem... the only fix is to switch providers. Nothing will change until Covid goes away. I’m sorry but this is the truth and I’m just trying to save you hours of time on hold with cox reps. Do not fall for their bs to upgrade your internet , this will not do anything trust me .

    Sorry, but this just isn't true. There are a lot of things other than over-subscription that can cause slow speeds and packet loss: loose connections, faulty interior wiring, faulty exterior wiring, defective tap, defective amplifier, RF ingress, etc. Almost everyone who complains about slow speeds ends up having one of the problems I listed once they post their modem signals and logs. Over-subscription is a problem but it's definitely not the only problem. People shouldn't give up without properly troubleshooting their issue.

      Here is a screenshot of my normal speeds now in Las Vegas.  700+ in the morning and 10 in the evening.  Everyday for the past week.  This is definitely a problem [at minimum] with the CMTS.

      These speed tests are taken hardwired out of the modem (CM100).  If I use a completely different modem (Arris SB8200), same result.  My neighbor gets the same speeds too (also SB8200).  I have new RG6 pulled (by Cox (twice)) to my DMarc where it hits a bonded bullet connector to another brand new piece of RG6 straight to my modem.  No wall jacks/attenuators/splitters/taps, nothing.  There is nothing left to troubleshoot from the curb to my house.  It's all new...and apparently acceptable or I'd never hit 700+

      I get what you're saying though and that's all possible scenarios in a lot of cases, but not in my case.

      The simple fact is Cox's greed has over subscribed and their nodes can't handle the demand.

        I’m running into the same exact problem here in Henderson. Totally fine speeds in the morning and by afternoon we are down to single digits. I thought it was possibly a modem problem. I didn’t have any issues until I upgraded speeds and got their modem (pano). I just ordered a new modem in hopes that would solve the problem but from what you are saying it looks like I’ll run into the same issue. I had 3 techs out here over the past two days and they can see that the node is overrun but why the sudden issue of the single digit speeds?  People have been working from home for months. What changed this past week?

    I can't agree with you more. Had a tech came out few weeks ago for the same ping spikes/packet loss issue, and everything is fine it's just everyone staying home and their infrastructure simply can't handle this situation. No plan to split node in the near future. Will a FCC complaint force them to split node?

    So.... Covid is over and the problems are still here. If only there were ANY other option in my area, Cox has a monopoly for the ability to lay new lines so we're stuck with terrible internet. Thanks

    Let me make life easier for you. I am a network engineer and communications specialist with over 16 years at Cox Communications. 

    If you are having slow internet and packet loss, there are a NUMBER of reasons why this can happen. Since I have a good modem, and an ethernet connection, here is my speedtest - Which btw I will run at 7 pm, and tomorrow, at several intervals and post here.

    I am in Virginia beach, and the test ran to Fairfax, Va. I am on the 500 down, 50 up speed and as you can see, I am easily getting what I pay for. Of course, my equipment is up to date, as is my computer. 

    So - Instead of believing what the OP posted, There are some things that can help if you are not getting good speed and you are having issues. I am in the forums quite often, and will help you out as much as possible. You would be surprised how easy it is to fix MANY issues.

      You aren't wrong, but OP's post was 4 years ago.  Cox has made a lot of infrastructure upgrades since then that improved performance.  Cox installed fiber in my neighborhood.  The node is about 100 feet from my tap.  My speeds are virtually identical to yours.

        I didn't look at the date, I should have. As for upgrades, my neighborhood has been untouched for decades, with the sole exception of their changing out the fiber to the node, with dark fiber.

      I am 100% positive that you and your associates are scamming people. I have found a loophole however. Stop your plan every 3 weeks or so and then restart a new one. That's the only way to get good wifi. Otherwise you get the best wifi in your neighborhood or hood when you first join for a couple weeks or even a month some times and then it drops to 1/10 the download speed, latency goes up 1,000%, everything flips on a dime. I'm not sure if the motums are only good for a couple weeks then brick causing this or what but I cancel and resign for wifi every couple weeks, never change wiring or nothing and jt has solved the issue. Before that I ran into this issue every one of the 5 times I signed up as I kept switching between providers. Now the problem is solved.

        You and your associates? I am retired my friend. I am a network engineer, holding certs in Novell, Micom, and Bay Networks, as well as in digital and analog communications and other disciplines. My last job in the military was AIS security at NSSF New London. 

        Additionally, my speeds are for my desktop computer, and my WiFi 6 Laptop without having restarted my modem, or my router, (CM2000 and RAXE300), for my laptop. It's been so long since my equipment was restarted I couldn't tell you when it last was. My plan I am signed up for is the 500 down and 50 up plan.
