CAX80 Uploading Issues

Ok I see things look on for power, kind low but well with in specs. 

Channels 7,8, and 9 have some Correctables but not horrible. 

Be sure there are no coax cable line splitters in the between the modem and ISP service box. 
Be sure your using good quality RG6 coax cable up to the modem. 
Start with removing any amplifiers, signal attenuators, or splitters from the coax.
From there check the line for kinks, damage, moisture in the line.
Check the connectors for improperly made ends, foil touching the copper coax line, loose connections, bad/old/cheap connectors, or corroded connections. Replace them if you do.

I'd find the devices that's having problems connecting and see if this helps. Possible this device is dragging something down causing wifi and upload issues. 

This version is supposed to have fixed a long standing 5Ghz upload issue in prior versions of FW. I tested this and a beta on my CAX80 last year to help NG check this. I used a ASUS GT-AX11000 and a NG RAXE500 set to wireless bridge mode and uploaded several Gigs of data to a cloud storage and saw no issues during any uploads. I believe I used manual channels 1 and 40 and AX and OFDMA were enabled and 40Mhz Coexistence was set as well. Beamforming and MIMO enabled too. 

Ok I see things look on for power, kind low but well with in specs. 

I know the upload channel power levels are low but comcast claims they can't fix them

what needs correcting?

Be sure there are no coax cable line splitters in the between the modem and ISP service box. yup already checked

Be sure your using good quality RG6 coax cable up to the modem. I am but replaced it anyways

Start with removing any amplifiers, signal attenuators, or splitters from the coax. there weren't any

From there check the line for kinks, damage, moisture in the line. from what we can see in the attic there isn't any

Check the connectors for improperly made ends, foil touching the copper coax line, loose connections, bad/old/cheap connectors, or corroded connections. Replace them if you do. again, hard to check in the attic but how much of the line we could see we didn't see anything weird

I'd find the devices that's having problems connecting and see if this helps. Possible this device is dragging something down causing wifi and upload issues. I did find it was the printer we forgot to re-connect BUT we have had issues for way longer than the 24 hours this printer was trying to connect.

This version is supposed to have fixed a long standing 5Ghz upload issue in prior versions of FW. According to Netgear Tech Support there is no long standing issue. Ugh! They also claim it's not the recent firmware update that is messing things up even though we didn't have problems until it came through.

They changed our DNS from auto to some google numbers (they remoted into my laptop)... didn't fix the problem.

They asked me to request Comcast give us a static DNS... comcast doesn't do that for residential customers.

My list of "things to try" is getting longer and longer but nothing is working! This is super frustrating since we work from home and it disrupts us all day long.

What devices are you using for the 5Ghz upload? 

Lets set manual channels 1 on 2.4Ghz and 40 on 5Ghz. 

Take the check mark out of the Enable AX and Enable 20/40Mhz Coexistence check boxes. 

Set Transmit Power to 50% on both 2.4Ghz and 5Ghz.

Ya they can fix them, thats on them.

Those should be reading mostly zeros, Items below could help:

Lines in this space been replaced?

So after connecting it, problem still happens?

You can try downgrading FW to prior version and see.

What devices are you using for the 5Ghz upload? 

2 cell phones and 2 windows laptops

Lets set manual channels 1 on 2.4Ghz and 40 on 5Ghz. done

Take the check mark out of the Enable AX and Enable 20/40Mhz Coexistence check boxes.  done

Set Transmit Power to 50% on both 2.4Ghz and 5Ghz. can't... it only gives 100, 80, 60, 40 and 20

Okay just checked and now it's worse. Having issues just sending an email with text only. crum!

So after connecting it, problem still happens? no there's nothing showing up in the logs anymore. THAT problems fixed lol.

What is the brand and model#s of the phones and laptops? 

Ok so disabling Smart Connect. Can you connect to the 2.4Ghz only SSID name and upload OK? 

Do you have Airtime Fairness enabled or disabled? It's disabled on mine. 

https://kb.netgear.com/23960/How-do-I-manually-update-the-firmware-on-my-NETGEAR-router

Possible. Something maybe we can get NG to stop if older version works...Worth trying if you can. 

iPhone XR and Samsung S22

HP Laptop and MSI Creator Z16

Disabled the smart connect and still cannot upload on either the 2.4 or 5

I didn't have Airtime Fairness enabled but enabled it to see if it helped and it didn't. It's back disabled again.

I tried to roll back the firmware but the downloaded file only gave me a .bin and it's supposed to be a .img or .chk

ugh!

Thank you for all your help with my issue. After spending the last 6 hours on and off the phone with Netgear Tech Support (not to mention at least 15 hours over the past several days!) and NOT getting it fixed we have decided to return the Nighthawk CAX80 and get a motorola.

We're DONE with netgear!!!

Good Luck.
