" ... Well done, Zoom! ... "
" ... A key thing to note about the Arris Surfboard 6141 and the Zoom 8X4 modem is that they are both QAM modulation modems that employ multiple channels (communication paths over a single wire, not TV channels). ... I am thrilled to report that the Zoom modem has been operating flawlessly for the past week and simply will not die, even though I'm throwing maximum traffic at it with a constant barrage of speed tests. ... Final note: Don't let the Zoom's price (about half that of the Arris) fool you. ... "

" ... After about a month and a half of use, it hasn't lost signal or required a reset even once. ... Using this modem in combination with a wireless ac WiFi router is also much more effective for providing strong, reliable coverage in my home when compared to the Xfinity modem/router combo units, plus I get more control over the settings (like being able to choose what channel my WiFi bands are on so I'm not competing for frequencies with the neighbors). ...
