ADSL2 +Modem-Router is a great way to make a network easier to use. With a DSL
Modem/Wifi Router Combo there is no need for the products that are separate and perform
separate functions. Instead, it is a combination of both router and modem in a single device. The
ADSL2+Modem used will be Netgear Nighthawk D7000 AC1900 (Kamal, 2019).
A hardware device that permits the machine to transmit data with an IS provider on a
connection over a landline. Arris SurfBoard SB6121 DOCSIS 3.0 Modem with a cable is the
perfect example of a one-cable modem (Kumar et al. 2018). Here is a comparative Analysis
between Netgear Nighthawk D7000 AC1900 and Arris SurfBoard SB6121 DOCSIS 3.0:
Difference between ADSL2+ and One Cable Modem:
DESCRIPTION ADSL2+MODEM-ROUTER:
(Netgear Nighthawk D7000

Definition : Netgear Nighthawk supports
ADSL2+ and VDSL2. Ultimate
Wifi speed of 1.9 Gbps and dual-
core processor that is powerful for
extreme performance. Amplifiers
that are high powered with external
antennas and Beam-forming +
improves the range and reliability.
Compatible with century link
(excluding VDSL), AT&T (U-
verse), Verizon (excluding
Arris Surfboard SB6121 gives the
user the complete media experience
with incredible broadband speeds.
Harnesses the power of DOCSIS
3.0 and has four downstream and
four upstream channel. Advanced
media services and speed up to 172
Mbps in each direction. These are
Modems that incorporate the cable
technologies that are latest.
