Modem: Netgear CM1000v2 Router: ASUS AC1300 Modem/router/PC all connected via CAT7 cables. So I've been experiencing terrible upload speeds for years. It's in and out. Somedays I get what I pay for and others I get below 1.00Mbps up. My plan is Gigabit down and 35Mbps Up. Cox is my ISP. I've changed all my cables, new routers, new modems, new line from the tap to the connection on my home. Nothing changes. It just seems to go slow when it feels like it at random days and random times, even during slow traffic hours when people are at work or early in the morning. Cox claims everything is fine on their end 🤣 . Techs come out and tell me everything looks good. A tech did tell me last time they came out that it's all on Cox's end and this is a common problem reported in my area and they are doing work to fix it. Shortly after that visit it ran great for months, great down/up speeds but the last few days its back again. As far as I can tell everything on my end is sound. I'm 99% sure Cox is the problem and the network in my area is just too congested. Cox will not admit any fault. I've filed with the FCC but have not had any luck with that. I've tested the connection over wifi and ethernet. I've tested from the modem directly to my pc via ethernet. I've tested from modem to router and to the pc. All net the same results when I'm having this issue, slow upload speeds. The ONLY issue I can seem to locate is that I've noticed my modem's firmware version is v6.01.07 however when I check Netgear's site for the version I should be running on with Cox it states V1.01.03 is the current authorized version. Cox will not upgrade/update my firmware since I did not get the modem though them, I asked. Netgear states only my ISP can change the firmware for this modem. I can't even find a download for any firmware for my modem at all. I don't think this would be the issue since the slow speeds are not consistent. I could be wrong? Here is all the log info from my modem: Cable connection info/logs - I believe the signals look good coming into the modem but I'm no expert on this stuff. Modem logs Recent speed test logs: Speed tests You can see its all over the place in the last day. Sometimes its perfect then it just dies. What causes this? Can something on my end cause this to go in and out? I assume that since it runs perfect some days that it can't be anything on my end. I cannot stress how much work I've put into my end. I can't figure out what would cause this other than Cox having a problem on their end. I am pretty sure Cox is the problem here but you never know, figured I'd give it a shot here and maybe I'll find out I've been overlooking something. Any suggestions? Questions? Any help appreciated. Thanks.

Look at those SPEED TEST results from right now. They are all wild. Sometimes it's super fast, but other times it drops way under 2 Mbps when you switch tests back to back. That is awful!

Right here, they all connect using CAT7 cables. They say I should use Cat 5e or Cat 6, but those aren't shielded and don't have flat wires. Instead, the cables must be round instead of flat, made of pure copper with a diameter between 22 and 24 AWG, and they cannot be CCA (Copper Clad Aluminum). Where did I buy them? Probably fake ones. Just some info from this forum link: https://forums. There are similar posts elsewhere to find.

Could a broken wire make my computer go fast for a while and then slow down later, or would it happen all over the place? I have used these cables for months without any problems at all.

Maybe, yes. 1. The cable or connection might be bad. A little twitchy plug can fix everything. 2. The internet provider's problem. When they tech said it was fine, did you check it on your own gear? But I agree with what came before. "Cat7" is probably not great.

I want to tell you about a problem I had with old cables, which were flat cat 6 or cat 5 and not shielded back when it first started. Even after buying new modems, routers, and even a USB ethernet port, the issue keeps happening because it feels like it is still there. Are my current cables just bad? Maybe they aren't up to standard. I recently bought some round cat 8 cables from Amazon on a whim after having too many bad ones before. Is cat 8 actually overkill? Probably not much. Now I am seriously considering getting round cat 6 unshielded cables if nothing changes with the new cat 8 ones. At this point, I am really doubting it is just a cable or connection problem because I have had this issue on many different devices and hardware all connected to this same thing. The tech visiters said everything was fine from my end. For some reason, every time I talk to Cox after the visit, they never seem to have any records of the tech coming out or what they actually noted. Their only fix is a reset and another tech visit. I am just tired of all this nonsense running back and forth. Even the customer service rep said that clearing my cookies and cache would magically solve it, but some of those suggestions are ridiculous and they don't seem to really look at my account history or listen to what I say several times I have explained I am testing over ethernet, yet they jump straight to wifi solutions even after I tell them it is the same for both. Some agents just don't know the difference between wifi and ethernet. I blame Cox and the tools/scripts their reps get more than anything. The agents are doing their best with what they were trained to do. Does anyone see if there are any alarms in my modem logs?

HERE are the cables I'm currently using, but keep in mind I've had this problem happen with all kinds of cables, mostly ones that are real and authentic like those you described. HERE are the new Cat 8 cables I just ordered. They have solid copper inside and extra shielding, and they're thicker than what you suggested (I bought them before you got back). What do you think?

The first cables are definitely fakes because the wire is too small, which automatically disqualifies them from being used properly. The problem is that terms like "cat" mean nothing; all standards use numbers instead of those letters. So a cat8 cable might be fake too. I don't know for sure what real standards require for cat8 cables since data centers only ever need them and they cost 10 to 20 times more than cat5e or cat6 cables. No vendors on Amazon will give you away expensive cables. Those cat8 wires might actually work better in some cases, but the wire size is still thinner than the standard 22 to 24 AWG range needed for most long runs. There is an exception where you can use a thicker cable (AWG 26) only for very short patch cables, not for longer runs where equipment needs cat8 speed. Even if you try it, the wires will never run at 40 Gbit if your equipment requires cat8 speeds; you need nothing better than cat5e which is rated to handle the full 1Gbit speed. Just buying a bigger number on the cable does not make it run faster or better. If you really needed something like 10 Gbit, you would buy a cat6a cable instead. I'm still not sure about your actual speed problem though, because your cable modem logs look fine. Do you have another computer to test on so we can be sure this isn't software? Maybe you could try booting up a Linux USB image, but that depends on how often this fails in real life. Although it doesn't happen very much, it could just be your neighbors' traffic since you share the total speed between your house and the ISP equipment. They usually have huge bandwidth now days, but I can see differences if I test between 5 AM and 11 PM. Sometimes the speed drops by 10% to 20%. Nothing that really matters but it still takes a while sometimes.

Also: Cat 7 cable is flat - that's a big problem right away. If you think about Cat 8, it looks like nonsense because reading those labels is pointless. Saying 26 AWG wires are better than 32 AWG is just comparing bad stuff to even worse stuff. Shielded cables need the ground wire connected correctly. Just get the cables back.

Hey Dverk, did you get a fix for this? I've been stuck on the same problem every single time. I'm running in circles and don't know what to do next. The only thing is switching ISPs, but if my issue isn't something else, why would that help? Sometimes ten minutes later it goes from 40mbps upload down to .08 like clockwork after 5:30 PM. Thanks a lot!
