N300 WiFi Router (N300R) User Manual
2-8 Safeguarding Your Network
v1.0, May 2012
• Region. This field identifies the region where the N300R router can be used. It might not be
legal to operate the wireless features of the WiFi router in a region other than one of those
identified in this field.
• Channel. This field determines which operating frequency is used. It should not be necessary
to change the wireless channel unless you notice interference problems with another nearby
wireless network. The WiFi router uses channel bonding technology to extend the bandwidth
for data transmission.
• Mode. This field determines which data communications protocol is used. You can choose
from:
– Up To 54 Mbps. Legacy mode, for compatibility with the slower 802.11b and 802.11g
wireless devices.
– Up To 145 Mbps. Neighbor Friendly mode, for reduced interference with neighboring
wireless networks. Provides two transmission streams with different data on the same
channel at the same time, but also allows 802.11b and 802.11g wireless devices. This is
the default mode.
– Up To 300 Mbps. Performance mode, using channel expansion to achieve the 300 Mbps
data rate. The N300R router will use the channel you selected as the primary channel and
expand to the secondary channel (primary channel +4 or –4) to achieve a 40 MHz frame-
by-frame bandwidth. The N300R router will detect channel usage and will disable frame-
by-frame expansion if the expansion would result in interference with the data
transmission of other access points or clients.
Note: In North America, the region cannot be changed, and is set by default to US.
Note: WEP and WPA security options are supported at 54 Mbps only.
Note: The maximum wireless signal rate is derived from the IEEE Standard 802.11
specifications. Actual data throughput will vary. Network conditions and
environmental factors, including volume of network traffic, building materials
and construction, and network overhead, lower actual data throughput rate.
