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.
Greenfield Mode
: Greenfield mode uses an 802.11n-only preamble to transmit packets that older wireless clients cannot interpret. Use of greenfield mode in a mixed
802.11 environment may result in degraded performance but can improve performance if all devices in the area are 802.11n compatible.
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.
WiPipe QoS
When WiPipe QoS (Quality of Service, also known as “Traffic Shaping”) is enabled, the router will control the flow of Internet traffic according to the user-defined rules. In
other words, Traffic Shaping improves performance by allowing the user to prioritize applications.
Enable WiPipe QoS
: Click on this box to open options for controlling Internet traffic. You can assign maximum Upload Speed and Download Speed values and define your
own Traffic Shaping rules.
WAN Interface Speeds
Upload Speed
and
Download Speed
: Setting the
Upload Speed
and
Download Speed
is required to control traffic flow accurately. Adjust the sliding bar to restrict
the maximum upload and/or download speed for the Internet source(s) you are using. For example, you might restrict the upload speed to prioritize available bandwidth for
download or to reduce overall bandwidth use in order to lower costs. It is recommended that you experiment with different values for your particular Internet connection for best
results.
NOTE: Upload speed is the speed at which data can be transferred to your ISP. Download speed is the speed at which data can be
transferred to you from your ISP. You can test your connection speeds with a service such as
speedtest.net
.
Queues
Queues and rules work in conjunction to prioritize bandwidth for the most critical operations. Multiple rules can be associated with one queue. Use rules to associate your more
critical operations with queues that have higher bandwidth settings. For example, you might have two queues, one for “critical” and one for “secondary” with critical having
most of the bandwidth percentage. Use rules to associate your most important bandwidth needs (POS system, VoIP, etc.) with the critical queue. Restrict the bandwidth
available for less important functions with the secondary queue.
Assign percentages of both upload and download bandwidth to each queue. If you assign 80% download bandwidth to the first queue, the next queue will be forced to be
