    Hi,
    We are using WM3700 wifi controller
    AP4600
    version 5.5.5.0-018R

    wlan "WiFi MacBook"
    ssid MacBook
    vlan 25
    bridging-mode local
    encryption-type tkip-ccmp
    authentication-type none
    no broadcast-ssid
    no answer-broadcast-probes
    protected-mgmt-frames optional
    wpa-wpa2 psk 0 knabGhe7Y
    data-rates 2.4GHz gn-only
    data-rates 5GHz a-only
    !

    It's working very good with 5GHz but poor or not connectivity when using 2.4GHz
    Macbook pro Mid 2009 - Wifi card Broadcom 43XX 1.0 (5.106.98.100.22)

    AND

    Macbook pro Mid 2010 - Wifi card Broadcom 43XX 1.0 (5.106.98.100.24)

    Same problem with about 20 Macbook pro

    Some idea ?
    Thanks

    Hi Pascal,

    It's most likely interference in the 2.4GHz frequency band. Where possible it's always best to try and use 5GHz as there is more spectrum available and less chance of interference. Have you tried different channels on the 2.4 radios and/or done a spectrum analysis and checked the SNR of your clients?

    Also, looking at the config you've pasted in, just check that TKIP encryption is disabled and use only WPA2 AES CCMP PSK. TKIP can impact performance but won't account for the 2.4/5GHz difference you're seeing.

    Hope that helps,
    Darrel.

    Please elaborate on what you mean by "poor connectivity":
    • Frequent disconnects
    • latency
    • packet drops
    • slow reconnects
    • slow to pull IP address
    • roaming issues
