   So, only 2 out of these magical 5 support my starving telephone.
   Betcha the DOCSIS 3.1 Cable Modem (CM2050V) Nighthawk® Multi-Gig 
2.5Gbps Cable Modem for XFinity Voice has NO WiFi.

   Now, i do not care about the speed on the WiFi, that is to support my 
"smart" phone which needs 3+bars to work reasonably well and i am lucky 
to get 1 bar almost anywhere.
   It is an Android meaning crap for calls; iPhone works ni same 
environment and reads as if 5+ bars.

   Phone switches over to WiFi for calls.

** Interesting; from that approved list there IS one that supports phone 
and WiFi*: NETGEAR C7100V...*but does that "WiFi Router" mean i gots tew 
$$pay$$ for yet another box for Tx/Rx air time?


   Then there are apparent contenders from the full list:
ARRIS	  SVG2482AC ♦  24×8	1.0 Gbps
ARRIS	  TG862R       8×4	343 Mbps
Motorola  MT7711       24×8	1 Gbps
NETGEAR	  C7100V       24×8	960 Mbps

   Well, am i glad that i am a liar here, there seems to be at least one 
cable modem that supports a telephone and WiFi.
   So (later) some research on those.

* What is this bit on color? All of the specs I have seen say "black" 
and by golly, the case is painted black.
   [making fun of the case color..now know 'color" in that situation 
means cable color]

* Battery backup...my Technicolor ha a place for an expensive battery 
for backup, and Comcast claims the battery does not last; neither giving 
hours, nor lifetime.
   So, what is the big deal, just plug it into your overburdened UPS.

PS: that bit about the pavers seen at 4 pixels years ago using Win7 and 
now gone; the present resolution is worse than i thought; we have been 
dumbed down by a factor of 8 as far as i can tell.
   If this crap continues, we may need multi-TerrorHertz computers to 
get TTY speed results at the keyboard/console.
