Wireless Mode : Select the WiFi clients with which the router will be compatible. Greater compatibility is a
tradeoff with better performance. For greatest compatibility with all WiFi devices, select 802.11 a/b/g/n or
802.11 a/b/g/n/ac.

Protection : In Auto mode the device will use protection to improve performance in mixed mode networks. Turn
protection off to maximize throughput with 802.11n clients.
Airtime Fairness : Airtime Fairness will attempt to balance air time between faster and slower wireless clients
to more fairly distribute bandwidth.
Channel Width : Selects whether the router uses a single 20 MHz channel to send/receive, or uses two adjacent
20 MHz channels to create a 40 MHz channel. Higher performance is possible with the 40 MHz channel.
Selecting Auto is generally best. Enabling WiFi as WAN will force 20 MHz only mode.
Extended Channel : When operating in 40 MHz mode the access point will use an extended channel either below
or above the current channel. Optimal selection will depend on the channels of other networks in the area.
MCS : 802.11n uses multiple Modulation Coding Schemes to enable higher throughput in various environments.
Since clients can dynamically change rates depending on environment, selecting Auto is generally best.
Short GI : Short GI is an optimization for shortening the interval between transmissions. May be incompatible
with older clients.
RADIUS Timeout : (Default: 3600 seconds) When using an Enterprise security mode clients will be forced to re-
authenticate with the RADIUS server at this interval in seconds. This allows administrators to revoke access so
when an attached client’s authentication expires, the client must re-authenticate.
RADIUS Retry : (Default: 60 seconds) When using an Enterprise security mode, if a RADIUS query fails to
receive a response from the server it will delay by this interval (in seconds) before attempting another query.
This helps protect the network from floods of authentication requests if the RADIUS server is temporarily
unreachable.
ETHERNET PORTS
Ethernet Port Configuration provides controls for your router’s Ethernet ports. There are three total ports:
by default, one WAN port and two numbered LAN ports. While default settings will be sufficient in most
circumstances, you have the ability to control: Mode (WAN or LAN) and Link Speed . Additional controls for WAN
ports are available in CONNECTION MANAGER .
Mode : WAN or LAN. By default there are two LAN (Local Area Network) ports and one WAN (Wide Area
Network) port.
•
Internet (WAN) is used as a possible source of Internet for the router
• Local Network (LAN) is for connecting a computer or similar device directly to the router with an Ethernet
cable.
