Can't upload to cloud with 5G wifi.

Hello Matthew,

Yes, I get the error any time I tried to upload a file (any size) to a cloud service (such as onedrive or box) or even try to attach it to an email (such as gmail and outlook). As soon as I switch to my 2G network, it works again.  I've contacted Netgear and they ran through some trouble shooting (such as changing the channels) but to no avail. 

I've read in other forums that a potential solution is a firmware update to the model side of the product from Xfinity. Yet when I called Xfinity they refused to helped me and told me that they can't support me unless I start renting an xfinity gateway. As you can imagine, I rather not go in that direction considering that I've already purchase an over $400 "top of the line" modem/router.

Yes, this is an issue accross all my devices, work laptop and desktop. I'm not sure whether this is an issue on my phone or not. 

I read in other forums here that the device manufacturer can only update firmware on the rounter side of the product and that only xfinity can update firmware on the modem side. I do have the latest router firmware or firmware from Netgear.

I've continued to google this issue and I've come accross the following chain:

Does this mean that my CAX80 is potentially non-funtional anymore? Some official word on Xfinity's experience with this would be helpful so I can know how to deal with Netgear.
