Nighthawk CAX30 I just downloaded v1.4.11.2

[idealboy89]

I just downloaded v1.4.11.2 from this page using my mobile internet and uploaded it to the router by logging into 192.168.1.1 and navigating to Advanced -> Administration -> Router Update

That fixed my internet connection instantly. 

NOTE: v1.4.11.2 is a much older version of the firmware than the latest one.

That is correct. I used the .bin file that was a part of the zip package

That link appears at the top of the Community page for this section.

https://kb.netgear.com/000065543/?_ga=2.5970099.1073564255.1670756476-997256614.1625128861

Here at least, the link goes nowhere.

Not very assuring when when Netgear tries to alert people to a problem with a broken link.

After everything broke yesterday, I moved to another (used) router for different connection failures. turns out Xfinity says they have an issue in my area, then xfinity texts me about this workaround so I think “maybe it’s me, not them”... I roll back to CAX, but the TM trick doesn’t work, I default the router, still nope. Then I read I should roll back the code. I’m 20 hours into this, worked from home off my work phone that I’m limited on data with poor signal. I’ve had weird issues where individual devices would lose connectivity the entire life of this modem:router.
Then I dig into the code and there’s stats from this month/last month and other odd remnants… did it default all the way!? Is it really xfinity or is it this coincidental update?? Am I going in circles? I’m in IT, how would an every day joe handle this when I’m near melt down status!?
I wish Costco would recall this turd. Good luck everyone, and thanks to contributors for your time and thoughts.

Downgrade the CAX30 to v1.4x if you still have WEB UI access to the modem. If you don't, try this to load the v1.4x FW file using a wired PC:

Hi,

When I unzip the file, i see a .bin file (CAX30-V1.4.11.2.bin). But when I look at CAX30 manual, it mentions that the firmware file should be either a .img or .chk file. Just want to make sure that .bin file is the one that you upload via web UI to get the firmware version to 1.4

Thanks
