Should I set all data rates on WLC4400 to 'Supported'?
On a WLC4404, the default data rates on the 802.11b/g Global Parameters are as follows:
1 Mbps - Mandatory
2 Mbps - Mandatory
5.5 Mbps - Mandatory
6 Mbps - Supported
9 Mbps - Supported
11 Mbps - Mandatory
12 Mbps - Supported
18 Mbps - Supported
24 Mbps - Supported
36 Mbps - Supported
48 Mbps - Supported
54 Mbps - Supported
** Data Rate 'Mandatory' implies that clients who do not support that specific rate will not be able to associate. Data Rate 'Supported' implies that any associated client that also supports that same rate may communicate with the AP using that rate. But it is not required that a client be able to use the rates marked supported in order to associate **
Is it recommended to set all data rates to 'Supported'? Many clients (a mixture of b & g) occasionally face a lot of disconnections and I received many syslog messages as follows:
