CAX30 Will Not Connect To Internet

AX7200, CAX30

Firmware 2.2.4.2

Provider Xfinity

I have a 600mbps Xfinity plan and was getting all of that 600 since 2024.  However, last two months I've been getting half of that.

I got in touch with Xfinity today.  "Sure we can fix that but since you have been inconvenienced, how about 800mbps for less money". 

I say sure, lets go.  The guy in India starts on it.  Does whatever he does.  I figure they just need to change the throttle setting and that's it.  Nope.  He resets the CAX30 remotely from that point on, the router never would connect to the internet.  Hours upon hours chatting with them.  7 techs later,  they tell me its is my CAX30 and everything up to it is good.  Nope.

I am certain the first tech that upsold me said he was loading a new boot file...

I've done multiple resets (power cycles) and a factory reset.  Still the same thing.  The internet light is off.  I've used the tools in the netgear portal and it shows that the cable connection is good.

I've made sure that in the Netgear portal in the advanced tab that metered connection is off.

What else can I do here?  The firmware is up to date (checked on the Netgear portal) and I am not sure if anything new was loaded by Xfinity.  Should I try loading an older version of the firmware  and hope that whatever might have been loaded by Xfinity gets written over?

I really appreciate any help.
