NightHawk CAX 30 slows until Factory Reset or config restore

This is crazy but I also purchased the same device through Costco ... and let me tell you it's been no picnic.... first I had the same exact problem, My speed would be less than what I had with the Xfinty modem around 700, I used to get 950. I tired every conciveable possible solution but I could never reliably find a fix that would correct the problem it would magically work sometimes and then it would drop to like 200...  then i turned back on the Armor protection and whalla .... back to 950 and all my wireless speeds went back to normal as well. I shut it off back to 200, turn back on 950 where is has remained ever since, with armor off always 200 with armor on 950. Netgear states that Armor should not have anything to do with it but all I know is with it off 200, with it on 950, reproducible every single time. There is ZERO question with my connection (could be Comast wouldn't suprise me, they are scantless). Try, if you experience the same thing maybe they'll stop calling me crazy. 

 

Let me know when you get to constant dropped and poor signal reception I've got the fix for that as well. Thanks to a Super User.. he nailed it.

I enabled Armor after paying for a subscription, but it made no difference. Just FYI.

I recommend you contact NG support and let them know what your having problems with. You may have a faulty unit. 

To my computer, mine runs through the CAX30 through a switch and then to my computer. With Armor off I got 200 with it on 950, like tunring on or off a light switch, as reliable as the sun coming up. Armor comes with a 30 day trial, I was suggesting using that. I don't know if the switch is what caused it or not, actually trying to replace the switch, but good luck searching the Netgear website for a switch that supports LACP, why is this so hard NETGEAR?!?!?! Their products are good, but after that it's a STRUGGLE to do anything, even find a simple swtich, but keep at it, when I finally got most of my stuff working like it's supposed to. It's been a significant upgrade to the Xfinity X7 

I had already used my trial up, but was willing to spend the $50 to see if it worked ;-). I fugure that in worst-case scenario, I have more security (maybe).

I'm glad it worked for you. I just ordered a 1Gb Ethernet usb c adapter for my computer along with a Cat8 cable to test through an ethernet port like the Guru says I should. I am highly doubtful it will make a difference in the test results, but I am wlling to give it a shot.

I also suspect that this might be an Xfinity/comcast compatibility issue. Comcast had to re-provision my router after a factory reset. MyXfinity app did not recognize the router was even connected for another day, even though I was getting Internet through it. Xfinity tech support said that its possible to have internet even though their systems do not recognize that an un-provisioned router is connected, but that service would be unpredicatable. Then MyXfinity app reported my router needed to be updated to newer equipment, which is a laugh. After another day MyXfinity app simply says I have a non-supported personal router connected. With this kind of weird stuff going on, it would not surprise me that all of this "unpredictable behavior" is really due to Xfinity. Xfinity has been unreliable in every way for me here in Atlanta.

The only thing that is predictable is that I can temproarily fix the situation be simply reloading the backup config and rebooting. 

     Oh it's 100% Xfinity all the way. I literally hate them with a passion. You've tapped into my Xifintiy is a giant corrupt coporate liar conspiracy part of my SOUL.

     What they did to me is they provisioned my speed and I cannot get an IVp6 address to my computer and my speed is limited to the 950 on my computer, however, my Xbox Series X is directly connected to the CAX30 through a Cat6 cable and it gets speeds almost to 1100. I thought well that's got to be a mistake, but NOW I think it could be my switches? Maybe that's why it works on my Xbox but not my computer. 

     My tier speed is 1.2 Gbps and even though the CAX30 is capable of 2.5gbs they say it's only "Comcast Rated" for 800, which is nowhere to be found on your shiny CAX30 packaging but they do quickly mention it on their website if you check everything (kind of a crummy move on Netgears part if you ask me) funny how the same exact same hardware is rated for 1Gbs on both Cox and Spectrum. Because my tier speed is faster than the "Comcast Rated" speed of 800, they provision the CAX30 to I believe DOCIS 3.0 and isn't allowing you/me to use the DOCIS 3.1.

     I never asked to be on the 1.2 tier I was automatically "upgraded for free" by them. LOL Xfinity for free? Please what's the catch? By putting me at the higher tier, if I go online and "check my euipment" it'll say not supported because 1.2Gb speed to high for your equipment and you'll need XYZ euipment to be supported. If you notice those options are even more expensive. I believe this is on purpose for 2 reasons. 1) to purchase that much more expensive equipment, will pretty much negate the "save rental fees" as it will take forver to recoup your money so people will skip it and continue to rent. 2)  "upgraded" which caused my service to be downgraded to DOCIS 3.0 from 3.1. Why would they do that? I can only guess it's so they can save on bandwith for business customers even though its a service your paying for. I hate them. 

     I'm going to replace my switches with LACP capable switches and see if like the Xbox it will change my status of HDD managed Ivp6 provisioning. But its a stretch, but whatver I'd rather link the ports and use 2.5gbs instread of the seperate 1gb each. Plus I would do anything to subvert Comcast cause I can't stand them. 

Oh and my Xbox does get an IVp6 address where my comptuer does not 

Comcast/Xfinity sucks, no doubt. My problem is so intermittant and unpredictable, it's nearly impossible to troubleshoot. Router or Xfinity? Who knows. At least we have both in-common. Neither knows the true source.

I'm thinking about applying a gummi bear fix to smooth things out. Just don't know how to get the router to eat it. Ideas?
