Problems with CM1150V upstream on Comcast Xfinity

So it makes sense that the BGA3131 is designed to operate up to 205MHz.  However, notice the sentences I've highlighted.  In my case, Comcast is running four upstream QAM channels (no upstream OFDM) at frequencies of 173MHz, 273MHz, 303MHz, and 367MHz.  So not only are they asking the CM1150V do do something it was never designed to do, they are blatantly violating the DOCSIS 3.1 spec!

sleat I've read this thread multiple times (having my own Upstream Issues!) and took this at face value;

but only just spotted this fundamental error in your analysis ..........

The Comcast Upstream frequencies are not as you indicate, you are a factor of 10 off 

i.e. they are 17.3MHz, 27.3MHz, 30.3MHz and 16.7MHz 

i.e. 17300000 Hz (5 zeros) = 17,300,000Hz or 17.3MHz 

So actually operating well within the DOCSIS 3.1 Spec and well within the design capability of the Chipset. 

As I've said I'm having my own Upstream Issues with my CM1150V (and actually got a replacement from Netgear) and there is definitely a problem - but it's not because it's being asked to operate outside its spec.
