CAX80 won't upload 5GHZ network

I cannot upload on the 5ghz network with the cax80 modem.  Browsing websites/small data transfer is fine. But large files (wetransfer, onedrive, google drive) does not work.

 

Just had a comcast tech out.  No issues with the line.  Modem reprovisioned.  Etc.

 

Factory resetting modem does not resolve.  Modem has latest firmware.

Re: CAX80 won't upload 5GHZ network

What Firmware version is currently loaded?

 

Is Smart Connect enabled? 

What channels are you using?

What devices do you have connected to the 5Ghz radio?

 

This is a known issue:

@tdalias 

Is it still an issue for you? There's another thread about this (CAX80 can't upload 5GHZ network) and after providing logs and what not nothing happened. That thread is closed now, and I just bought a new modem router because I gave up on it, but decided to give it one more try and test run uploading on 5GHz on several OS and various browser and I have encountered zero issues now.

My guess is that they have fixed it somehow, I have no other explanation. I am still keeping my new Motorola modem router at end, but think of returning it if I keep a smooth 5GHz upload.

Re: CAX80 won't upload 5GHZ network

I am having this same exact issue.  Xfinity has been out twice to check all the lines and no issues there.  I have also factory reset my router and nothing changed.  This started happening mid August 2022. I can email attachments, but I can't even upload a small screenshot to Slack unless I use 2.4G or the wire

Re: CAX80 won't upload 5GHZ network

What FW version are you using? 

 

NG is aware of the problem. Were hoping that next FW version will resolve this. I tested a beta and it fixed this issue however, presented a different problem on my modem which I had to send in my modem to get it fixed so I don't recommend using the beta version. I don't know when new FW will be forthcoming. 

 

Just what works best for now.

Yeah I have a workaround so I'm not too fussed, but I work from home so it has caused me a number of issues.

I have v2.1.3.5 and it says there are no updates available

Understand. Will keep on them about this. From what I know, there is a fix, just needs to get into good working FW.

Re: CAX80 won't upload 5GHZ network

I returned the Motorolla router/modem and of course afterwards my upload issues started again on 5GHz. Good to know, however, that there will be a fix soon. Is there a way to be automatically notified when a new FW is available?

I logged into routerlogin.net and tried to update from there and nothing was available

I also downloaded Firmware Version 2.1.4.2 https://www.netgear.com/support/download/?model=CAX80

and looked for the file ending in either .img or .chk per https://kb.netgear.com/23960/How-do-I-manually-update-the-firmware-on-my-NETGEAR-router

Re: CAX80 won't upload 5GHZ network

Interesting.

 

The .bin file is what you use with a web browser when connected to the CAX web page and using the FW update web page to select this .bin file from your PC to upload to the router side of the modem. Do not attempt to open the .bin file. It gets sent thru the modems web page using the web browser.

Thank you and please excuse my ignorance as I've never had to do this before. On http://www.routerlogin.net I go to Advanced -> Router Update and browse for the .bin file and upload it here?
