QoS Setup
. The QoS Setup screen displays, as
shown in
Figure 5-8 on page 5-19
.
2.
Click
Add Priority Rule
.
3.
From the
Priority Category
list, select
Ethernet LAN Port
. The QoS - Priority Rules screen
changes:
4.
From the
LAN port
list, select the LAN port that will have a QoS policy.
5.
From the
Priority
drop-down list, select the priority that this port’s traffic should receive
relative to other applications and traffic when accessing the Internet. The options are Low,
Normal, High, and Highest.
6.
Click
Apply
to save this rule to the QoS Policy list and return to the QoS Setup screen.

QoS for a MAC Address
To create a QoS policy for traffic from a specific MAC address:
1.
From the main menu, under Advanced, select
QoS Setup
. The QoS Setup screen displays, as
shown in
Figure 5-8 on page 5-19
.
2.
Click
Add Priority Rule
.
3.
From the
Priority Category
list, select
MAC Address
. The QoS - Priority Rules screen
changes:
4.
If the device to be prioritized appears in the MAC Device List, select it. The information from
the MAC Device List is used to populate the policy name, MAC Address, and Device Name
fields. If the device does not appear in the MAC Device List, click
Refresh
. If it still does not
appear, you must complete these fields manually.
5.
From the
Priority
drop-down list, select the priority that this device’s traffic should receive
relative to other applications and traffic when accessing the Internet. The options are Low,
Normal, High, and Highest.
6.

Overview of Home and Small Office Networking
Technologies
Common connection types and their speed and security considerations are:
•
Broadband Internet
.
Your Internet connection speed is determined by your modem type,
such as ADSL or cable modem, as well as the connection speed of the sites to which you
connect, and general Internet traffic. ADSL and cable modem connections are asymmetrical,
meaning they have a lower data rate
to
the Internet (upstream) than
from
the Internet
(downstream). Keep in mind that when you connect to another site that also has an
asymmetrical connection, the data rate between your sites is limited by each side’s upstream
data rate. A typical residential ADSL or cable modem connection provides a downstream
throughput of about 1 to 3 megabits per second (Mbps). Newer technologies such as ADSL2+
and Fiber to the Home (FTTH) will increase the connection speed to tens of Mbps.
•
Wireless
.
Your Wireless-N 300 Router Model WNR2000v2 provides a wireless data
throughput of up to 300 Mbps using technology called multiple input, multiple output
(MIMO), in which multiple antennas transmit multiple streams of data. The use of multiple
antennas also provides excellent range and coverage. With the introduction of the newer WPA
and WPA2 encryption and authentication protocols, wireless security is extremely strong.
To get the best performance, use RangeMax NEXT adapters such as the WN511B for your
computers. Although the RangeMax NEXT router is compatible with older 802.11b and
802.11g adapters, the use of these older wireless technologies in your network can result in
lower throughput overall (typically less than 10 Mbps for 802.11b and less than 40 Mbps for
802.11g). In addition, many older wireless products do not support the latest security
protocols, WPA and WPA2.

Powerline
.
For connecting rooms or floors that are blocked by obstructions or are distant
vertically, consider networking over your building’s AC wiring. NETGEAR’s Powerline HD
family of products delivers up to 200 Mbps to any outlet, while the older-generation XE
family of products delivers 14 Mbps or 85 Mbps. Data transmissions are encrypted for
security, and you can configure an individual network password to prevent neighbors from
connecting.
The Powerline HD family of products can coexist on the same network with older-generation
XE family products or HomePlug 1.0 products, but they are not interoperable with these older
products.
•
Wired Ethernet
.
As gigabit-speed Ethernet ports (10/100/1000 Mbps) become common on
newer computers, wired Ethernet remains a good choice for speed, economy, and security.
Gigabit Ethernet can extend up to 100 meters with twisted-pair wiring of Cat 5e or better. A
wired connection is not susceptible to interference, and eavesdropping would require a
physical connection to your network.
Assessing Your Speed Requirements
Because your Internet connection is likely to operate at a much lower speed than your local
network, faster local networking technologies might not improve your Internet experience.
However, many emerging home applications require high data rates. For example:
•
Streaming HD video requires 10 to 30 Mbps per stream. Because latency and packet loss can
disrupt your video, plan to provide at least twice the capacity you need.
•
Streaming MP3 audio requires less than 1 Mbps per stream and does not strain most modern
networks. Like video, however, streaming audio is also sensitive to latency and packet loss, so
a congested network or a noisy link can cause problems.
Note:
Actual data throughput will vary. Network conditions and environmental factors,
including volume of network traffic, building materials and construction, and
network overhead, can lower actual data throughput rate.

Backing up computers over the network has become popular due to the availability of
inexpensive mass storage.
