Hello everyone,

it is the second time (in two different Companies) that it happens that after a reboot needed for a firmware upgrade the 2.4 GHz wifi profile does not work properly:

For example this morning I had a printer that was not able to connect wirelessly with the AP after the V7.00(ABYW.2) update: it was sufficient to reboot the AP to let the printer goes online.

Same thing happened in the previous V7.00(ABYW.1) update from 6.55 (if I remember its release number correctly) with another production site.

Anyway it seems a random issue: I have multiple sites, only few reports

    Is it a HP printer?

    I have mine to a USG60W and it goes offline after some hours being on and have to press the power button on printer to connect.

    It could be that as the AP goes off line when doing the firmware for a long time the printer goes offline or sleep mode

    It is an EPSON WorkForce, setup for always on and standby after 5 mins of no activity.

    A part from when the Company has blackouts that EPSON is always ready for printing.

    Those two different disconnections for two different Companies (after AP firmware upgrade) happened with that printer which I was referring to earlier and with a Daikin A/C unit, exactly the morning after a scheduled firmware upgrade of the AP.

    For this reason I highlighted some doubts on that happening.

    To be sure I rebooted firstly the appliances (printer and the A/C unit) but this action does not solved the problem while rebooting the AP fixed the connection issue.

    Hi @GiuseppeR

    As we discussed via message, the issue you're experiencing appears to be similar to one previously mentioned on the forum:

    https://community.zyxel.com/en/discussion/comment/68925#Comment_68925

    However, to determine if it is the same issue, we need to review the diagnostic information from the AP. Please collect the diagnostic info from the APs when the issue reoccurs and send it to us via private message for further investigation.

    Additionally, has the issue only occurred with the printer, or have you also tried connecting a mobile phone or desktop to the 2.4GHz network?

    Hello @Zyxel_Nami

    I use 2.4 GHz spectrum mainly for IoT things (e.g. printers, sensors, A/C units).

    Mobile devices go to 5 GHz.

    Hi @GiuseppeR

    Regarding the case I mentioned earlier, where the 2.4GHz was not visible to clients, could you please help verify if your issue is the same? You can do this by checking if the IoT devices/desktop/phone can detect the 2.4GHz SSID.

    Hello @Zyxel_Nami

    the 2.4GHz SSID was not reachable by IoT things, they could not see that network.

    Rebooting the AP solved the issue
