It may not be new but i just got the upgrade: built-in WIFI and horrendous 1Ghz speeds if you can pay such bills.
I had an old LinkSys wifi - 2nd owner - the damn thing crashed so often the previous owner had broken the front panel reset button ! And it's reach: not so good.
The upgrade modem for COX (ARRIS/Motorola) has two wifi that reach the whole indoors comfortably.
Earlier modems allowed only two IP addresses if you had a family you had to set up your own DMZ. Today you get 5 IP minimum, 9+ if you pay up. And earlier also didn't have the web setup (moreso the features needed) to really do any kind of job. New one? All you really need and a bit more. The last one I didn't even check features of because I'd already had a stable setup (since the 90's that needed maintenance in terms of (every 5 years? too long to measure)).
Only prob is how long they took to arrive :)
Huge time saver, no need for extra routers or software routers!
