NETGEAR RangeMax™ NEXT Wireless Router WNR834B User Manual
• 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. For more information on the wireless channel frequencies, see
Communications" in Appendix
• Mode
This field determines which data communications protocol is used. You can choose from:
— g only
Dedicates the WNR834B to communicating with the higher bandwidth 802.11g wireless
devices exclusively.
— g and b
Provides backward compatibility with the slower 802.11b wireless devices while still
enabling 802.11g communications.
— Up To 126 Mbps
Provides two transmission streams with different data on the same channel at the same
time.
— Up To 240 Mbps
Uses channel expansion to achieve the 240 Mbps data rate. The WNR834B 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 40MHz frame-by-frame bandwidth. The
WNR834B 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: 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.
• Security Options
The selection of wireless security options can significantly affect your network performance.
The time it takes to establish a wireless connection can vary depending on both your security
settings and router placement. WEP connections can take slightly longer to establish. Also,
WEP, WPA-PSK and WPA2-PSK encryption can consume more battery power on a notebook
computer, and can cause significant performance degradation with a slow computer.
Instructions for configuring the security options can be found in
