Some restrictions apply to combinations of settings on the Channel Configuration and Performance
tabs.
• For fixed data rate configurations:
• If the configured channel is in the 5 GHz band or the Channel Set Band/List is 5 GHz,
System Determined, or Both, then at least one of the fixed rates must be other than an 11b
rate (1,2,5.5,or 11).
• If the configured channel is in the 2.4 GHz band or the Channel Set Band/List is 2.4 GHz
only, then only 11b/g rates are accepted.
• Assigning an enhanced rate (72, 96, and 108 Mbps), requires that the enhanced rates option
be enabled.
• To enable the Dot11 QoS settings on the Performance tab, you must enable the standard Dot-11
extensions on the 802.11 Policy tab (see “802.11 Policy” on page 69).
Ack Mode Determines the acknowledgement policy for data packets. The following
selections are available:
• Immediate Ack – Acknowledgement is sent for every packet received.
This is the default setting.
• No Ack – No acknowledgement is sent when data packets are received.
• To enable high performance, use this setting together with one of the
enhanced data rates.
• If this setting is used, then auto-adaptation cannot be enabled for the
selected radio. Only the fixed rate setting applies.
• This mode setting can be used for operations with Airgo clients.
• Auto-ack – The acknowledgement policy is selected automatically based
on current link conditions.
Dot11 QoS Enables or disables 802.11e QoS. If enabled, the MAC mode is set to EDCF
or HCF. If disabled, then the MAC mode is DCF. It is recommended to accept
the default of Enabled.
