Why Should I buy own modem ?
In US most of the time you will be paying a rent of a cable modem from your ISP.
For example,
Comcast & Time Warner Cable TWC Router modem rent is in between $8 ~ $10 per month.
So in long run (Just one year of time-frame) if you buy a $90 cable modem then you will get ROI [Return On Investment] within a year.
Note : However some ISP’s like Charter integrate the modem rental fee into their prices, so you won’t save any money even-if you buy your own cable modem !!
There are so many cable modem models from Arris Motorola, then which cable modem is best for my home & office ?
All the websites telling high end technical funds are not useful to most of the people who only wants to select a simple cable modem for their home or office. Even I have over 25 years of R&D Expertise I feel unfair to bombard with my knowledge to you 😛
So I have sent some time to prepare simple feature and specs chart , including my easy to understand conversion of technical specifications for you. I am sure you need not refer to any other website after looking at this (No harm, but doing it will only confuse you a tonne !)
** TIP ** One most important thing is the pricing strategy ! Even higher end specification modem you may get for cheaper price due to dynamic pricing strategy, hence don’t get astonished if you see Arris Surfboard SB6141 at much lower price than Arris Surfboard SB6121 !
