Using Universal Plug and Play
Universal Plug and Play (UPnP) helps devices, such as Internet applian\
ces and computers, 
to access the network and connect to other devices as needed. UPnP devic\
es can 
automatically discover the services from other registered UPnP devices o\
n the network.
Note:  If you use applications such as multiplayer gaming, peer-to-peer 
connections, real-time communications such as instant messaging, 
or remote assistance (a feature in Windows XP), you should enable 
UPnP.
To turn on Universal Plug and Play:
1.  Select  UPnP under Advanced the main menu. The UPnP screen displays.

2. The available settings and information displayed in this screen are:
•     Turn UPnP On. UPnP can be enabled or disabled for automatic device configuration. 
The default setting for UPnP is disabled. If this check box is not selected, the router 
does not allow any device to automatically control the resources, such as port 
forwarding (mapping) of the router.
•     Advertisement Period. The advertisement period is how often the router broadcasts 
its UPnP information. This value can range from 1 to 1440 minutes. The default 
period is 30 minutes. Shorter durations ensure that control points have current device 
status at the expense of additional network traffic. Longer durations might 
compromise the freshness of the device status but can significantly reduce network 
traffic.
•     Advertisement Time To Live. The time to live for the advertisement is measured in 
hops (steps) for each UPnP packet sent. The time to live hop count is the number of 
steps a broadcast packet is allowed to propagate for each UPnP advertisement 
before it disappears. The number of hops can range from 1 to 255. The default value 
for the advertisement time to live is 4 hops, which should be fine for most home 
networks. If you notice that some devices are not being updated or reached correctly, 
then it might be necessary to increase this value.
•     UPnP Portmap Table. The UPnP Portmap Table displays the IP address of each 
UPnP device that is currently accessing the router and which ports (Internal and 
External) that device has opened. The UPnP Portmap Table also displays what type 
of port is open and whether that port is still active for each IP address. 
3. Click Apply to save your settings.
Changing the MTU Size
The Maximum Transmission Unit (MTU) is the largest data packet a network device 
transmits. When one network device communicates across the Internet with another, the data 
packets travel through many devices along the way. If any device in the data path has a lower 
MTU setting than the other devices, the data packets must be split or “fragmented” to 
accommodate the one with the smallest MTU. 
The best MTU setting for NETGEAR equipment is often just the default value, and changing 
the value might fix one problem but cause another. Leave MTU unchanged unless one of 
these situations occurs:
•     You have problems connecting to your ISP, or other Internet service, and either the 
technical support of the ISP or of NETGEAR recommends changing the MTU size. These 
might require an MTU change:
-A secure website that will not open, or displays only part of a Web page
-Yahoo email
-MSN
-America Online’s DSL service
•     You use VPN and have severe performance problems.

   Chapter 6:   Fine-Tuning Your Network   Wireless-N 150 Router WNR612v2 User Manual 
•     You used a program to optimize MTU for performance reasons, and now you \
have 
connectivity or performance problems.
Note:   An incorrect MTU setting can cause Internet communication 
problems such as the inability to access certain Web sites, frames 
within Web sites, secure login pages, or FTP or POP servers.
If you suspect an MTU problem, a common solution is to change the MTU si\
ze to 1400. If you 
are willing to experiment, you can gradually reduce the MTU size from th\
e maximum value of 
1500 until the problem goes away. The following table describes common M\
TU sizes and 
applications.
Table 6.  Common MTU Sizes   
MTUApplication
1500 The largest Ethernet packet size and the default value. This is the typi\
cal setting for 
non-PPPoE, non-VPN connections, and is the default value for NETGEAR rou\
ters, 
adapters, and switches.
1492 Used in PPPoE environments.
1472 Maximum size to use for pinging. (Larger packets are fragmented.)
1468 Used in some DHCP environments.
1460 Usable by AOL if you do not have large e-mail attachments, for example.
1436 Used in PPTP environments or with VPN.
1400 Maximum size for AOL DSL.
576 Typical value to connect to dial-up ISPs.
To change the MTU size:
1. In the main menu, under Advanced, select  WAN Setup. 
2.  In the MTU Size field, enter a new size between 64 and 1500.
3.  Click  Apply to save the new configuration.

Quality of Service
Quality of Service (QoS) is an advanced feature that can be used to pr\
ioritize some types of 
traffic ahead of others. The Wireless-N 150 Router WNR612v2 can provide \
QoS prioritization 
over the wireless link and on the Internet connection. 
Using WMM QoS for Wireless Multimedia Applications
The Wireless-N 150 Router WNR612v2 supports Wi-Fi Multimedia Quality of \
Service (WMM 
QoS) to prioritize wireless voice and video traffic over the wireless l\
ink. WMM QoS provides 
prioritization of wireless data packets from different applications base\
d on four access 
categories: voice, video, best effort, and background. For an applicatio\
n to receive the 
benefits of WMM QoS, both it and the client running that application mus\
t be WMM enabled. 
Legacy applications that do not support WMM, and applications that do no\
t require QoS, are 
assigned to the best effort category, which receives a lower priority th\
an voice and video. 
Configuring QoS for Internet Access
To specify prioritization of traffic, you must create a policy for the t\
ype of traffic and add the 
policy to the QoS Policy table in the QoS Setup screen. 
To create a QoS policy:
From the main menu, under Advanced, select QoS Setup. The QoS Setup scre\
en displays:
WMM QoS is enabled by default. You can disable it by clearing the 
Enable WMM check box 
and clicking Apply .
QoS for Applications and Online Gaming
To create a QoS policy for traffic for specific applications or online g\
ames:
1. From the main menu of the browser interface, under Advanced, select QoS \
Setup. The

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 site\
s 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 anoth\
er site that also 
has an asymmetrical connection, the data rate between your sites is limi\
ted 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 (M\
bps). Newer 
technologies such as ADSL2+ and Fiber to the Home (FTTH) will increase\
 the connection 
speed to tens of Mbps.

•     Wireless. Your Wireless-N 150 Router WNR612v2 provides a wireless data throughput of 
up to 150 Mbps. 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 wireless 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.
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.
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.
