What did they say in the MODmail last night? That there is no bootfile for it for the higher speeds? That is what they told me.

Thank you for your patience u/Iwillnit4getus! I noticed one of the main resources we use for determining which customer owned modems are compatible does not align with the public site’s information. I have gone ahead and submitted feedback to address this concern.

At this time, I’d like to provision the modem to see if we can update the boot file to receive the higher upload speeds. If that doesn’t work, I’d like to open a ticket with our engineers to make sure the Arris S34 is eligible.

If you could please send me a Modmail message with your full name and full address.

Was the provision and boot file update successful in getting them the next-gen upload speeds? If so, I'd like to give it a try...
