AP55c 5ghz defaulting to 24mb/s connection.

IanMorehouse

Hi folks,

I am having performance issues with my AP55c 5ghz channels. The testing is being done within 2 metres of the AP55c.

When using the 2,4ghz channels my devices connect at 144mb/s.

When using the 5ghz channels they conect initially at a high speed, but within seconds drop to 24mb/s. I have tried restarting the AP55C. This was happening before the latest UTM 9.5xx release.

The devices used for testing are

Mac Bok Pro (mid 2014)

iPad min 2

iphone 6.

I have had connections speed over 800mb/s previously.

Any ideas as to how to fix the problem. I don't see any way of reflashing the AP55c at this stage.

    Hi Bob,
    no solution.
    On the XG it shows 6mb/s as the default connection speed. I was experimenting by copying files from MBP to mac mini, the XG wasn't handling the traffic (at least the graphs didn't show any traffic, which was a couple of gbs), but the connection showed 650mb/s for the entire transaction. The data was being handled within the switch which interesting because it was a wifi to ethernet connection.
    I suspect the issue was caused when I installed a Netgear PoE switch.
    At the moment my internet is limited, all my landlines have been disconnected when the lines tech was repairing a neighbours pone/adsl service.

    Everything has been restored, but the 5ghz device show 24mb/s for the mac and 6mb/s for the android.

    I have the latest beta installed, no change.

    I have tried the iphone on the 5ghz system at work at the phone connects between 100mbs/ to over 500mb/s.


    So in summary, something is broken with the 5hgs AP55C AP.

    Update. Replaced my AP10 on the XG. Noticeable improvement in the 2.4ghz connections.

    Connection speed doubled on most devices (max 150mb/s), but not going to the 300mb/s though as per specifications..

    Connection speed on the 5ghz connection still sitting around 6mb/s. This is for both Android and Apple devices. Apples running 9.3.3 and 10.11.6.

    Will connect the second AP55 in place of the AP55c on the UTM and see what happens.

    Replaced the AP55c with the AP55 and the results are the same.

    Also when running both AP55 with in 3 metres of each other, both connected on channel 36 even with auto channel enabled.

    Very disappointing.
