I use zone flex 7982. The encryption in SSID is disabled. 11n is enabled by default in 20MHz. I want to disable 11n and set the radio to 802.11g mode. Please tell where is the option for that.
That is correct. You could do the opposite, disable CCK 802.11b-only clients with
'ofdm-only' on the WLAN, but we cannot disable 802.11n unless WEP, or WPA
with TKIP, are the encryption/cipher methods.
