Keep in mind that the 343 mbs speed is the max theoretical speed if no one else was sharing the channels the modem is on. Most ISPs won't activate a modem for a plan that is over 1/3-1/2 that max speed so the highest plan that they'd let you use this on is probably somewhere between 100 and 150mbs. Check your ISPs supported modem list to be sure and if you have a faster plan than that you'll definitely need a better modem. With that said the modem should pay for itself in months based on what ISPs are charging for renting a modem these days.

I still have a modem docsis 2.0 and it's still working since 2012. Still don't get why these are different??

thanks for sharing

DOCSIS 3.0 really isn't all that different from DOCSIS 2.0. Really the biggest change is 3 bonds multiple channels together while 2 is single channel only. The bandwidth possible per channel is the same as is most other things just DOCSIS 3 modems start at 4 download and 4 upload channels and go up to 32x8 which makes them significantly faster than DOCSIS 2.

DOCSIS 3.1 is actually a much bigger change from 3 than 3 was from 2DOCSIS 3.1 First released in October 2013, and updated several times since, the DOCSIS 3.1 suite of specifications support capacities of at least 10 Gbit/s downstream and 1 Gbit/s upstream using 4096 QAM. The new specs do away with 6 MHz and 8 MHz wide channel spacing and instead use narrower (20 kHz to 50 kHz wide) orthogonal frequency-division multiplexing (OFDM) subcarriers; these can be bonded inside a block spectrum that could end up being about 200 MHz wide.[l=[6]][/l]https://en.wikipedia.org/wiki/DOCSIS#cite_note-6 DOCSIS 3.1 technology also includes some new energy management features that will help the cable industry reduce its energy usage, and the DOCSIS-PIE[l=[7]][/l]https://en.wikipedia.org/wiki/DOCSIS#cite_note-7 algorithm to reduce bufferbloat. [l=[8]][/l]https://en.wikipedia.org/wiki/DOCSIS#cite_note-8 In the United States, broadband provider Comcast announced in February 2016 that several cities within its footprint will have DOCSIS 3.1 availability before the end of the year.[l=[9]][/l]https://en.wikipedia.org/wiki/DOCSIS#cite_note-9 At the end of 2016, Mediacom announced it would become the first major U.S. cable company to fully transition to the DOCSIS 3.1 platform.[l=[10]][/l]https://en.wikipedia.org/wiki/DOCSIS#cite_note-10
