3Com AirConnect 9550 Access Point with MacBook - Wireless Connectivity Issue

Posted on 2009-12-21

Can anyone confirm the recommended wireless setting to setup up a wireless Access Point to connect with a Mac Book?  AES, TKIP? We have a few 3Com AirConnect 9550 11n 2.4+5GHz PoE Access Points in the office and we notice that the device gets full reception but has slow connectivity on the internet.  Microsoft Window users do not experience any issues when connected.  Both Mac books and PC Laptops see the SSID and show it as full reception.  Just complaints with the Mac Book users about connectivity and slow performance.   Any suggestions troubleshooting this on are appreciated.

    I use TKIP (WPA-2) on my macbook with no problems, but this is with Cisco Aeronet, Valuepoint and Linksys.  No experience w 3COM

    See if the Macs are having DNS problem. Try setting the DNS on one of the Macs manually to the Google public DNS servers at:        and

    and see it that makes a difference.

    What encryption are you using?  WPA or WPA2?

    Depending on the device, you may have to scale back to WPA as WPA2 does have more overhead for wireless clients dues to encryption strength.

    It broadcasts a 2.4 and 5GHz signal at the same time.  Currently using, WPA2(mixed)-PSK/AES.  If I switch from AES to TKIP a warning pop up appears telling me that switching to this setting may deteriorate my signal.

    I still recommend you try WPA. Your connectivity speed couldn't get any worse :)

    WPA TKIP on 2.4 connected best with Macbooks.
