AP30 unstable since 9.401

BarryG

Hi,

(currently running 9.402-7)

My AP30 frequently seems to reboot, after moving from 9.355 with VLANs to a new VM running 9.401 without VLANs.

Sometimes, I get email messages from the UTM "WARN-728 Access Point is Offline".

Here's the wireless.log entries from the last occurance:

    FYIs, it turned out to be a detached heatsink on my AP30.

    I can also add my box. I have a second AP10 in a remote part of my house, that had not been used for some month.

    The Ap10 does not even work for a short time. I reflashed it several times successfull, but it only shows as pending and when I accept it I have an endless loop. The logs show the same lines you all mentioned.

    It took me some time to come accross your post because it is not an AP30, but the symtoms are the same.

    Any news on when this fix is getting released?

    I'm on 9.408-4, and seem to be experiencing this on some of my AP30s.

    Any news would be appreciated, thanks.

    Hi, I've seen that but I'm assuming its a red herring as it appears separately from the crashes as well, iirc.

    BTW, I've noticed the easiest way to trigger the AP reboot is to visit a web site with a lot of images on each page, such as Tumblr, and scroll through them (forcing them to be loaded by the browser).

    Sophos Support found a workaround on my Problem

    They implemented an older FirmwareVersion for AP´s on my UTM 9.407-3
    After flashing the Accesspoint and reconnecting the AP connected  to UTM and pulled the older firmware

    AP is now is working and doing what it has to do

    This worked only after the UTM had been restartet

    So now I must not Update the UTM till they they fix this

    This has been send to Global Escalation Support BUg ID NUTM-5567

    That message occurs after "accepting" the AP-30.

    Throw my hat in the ring on this one also.  Added an AP-30 to the network today, it had been offline, as in physically disconnected, for months, and same thing happened here.

    Tried re-flash, that was successful, but still cannot get it (AP-30) to "stay attached" to the UTM...

    Considering it is now November, and the original question/issue was brought to light in May, I would be calling tech support every day.  This delay in fixing this issue is not acceptable.

    Hi Chris, as far as I know, there is no solution or workaround. I've applied the latest Up2Date last week.


    Sophos support is still occasionally looking at my system, but they have not mentioned any workarounds. I'm really not sure what they're actually doing, they don't tell me much.

    Case id is 6050739; I'm asking if there's also an ID for a bug tracker (Mantis or whatever they're using now).

    The easiest way to crash my AP is to visit a site with a lot of images such as Tumblr. Unfortunately, this means I can't browse a lot of the sites that I like to on my tablet or other wireless devices.

    I'm not happy with how long this has been going on with no workaround. If this was for business use, it would be completely unacceptable.
