HP OfficeJet Pro 9022e keeps losing connection to wireless network

Hello Pim,

Thank you for your cooperation and for providing the packet captures.

Upon review, we observed that no packet frames were transmitted between laptop B and the HP printer after the laptop received the mDNS reply from the printer, even in the successful print packet. The packet was captured at 11:49, whereas you mentioned that the printing commenced at 11:45. It lasted around 5 minutes. We would like to ask whether the print was also successful after 11:45, specifically from 11:49 to 11:51 (end of packet).

You mentioned:

I've noticed that I CAN'T ping another laptop at this moment. It doesn't matter on which AP I'm on; 100% packet loss.

⇒ In the Nebula log, it shows that the end devices are still connected to the AP as usual. Could you let us know if the end devices were able to access the internet during the times when printing was successful and when it failed? If the devices could access the internet but couldn’t communicate with each other, then this is likely where the problem lies.

For the next step, we suggest setting up a remote access session to dig deeper into this issue. If you're okay with this, please share your Team Viewer details and let us know your preferred time to leave the environment as is, especially if there’s no urgent need to print.

Since this problem doesn't come up often, and considering the time zone difference between us, as well as the limited overlapping time (we are available from 9 AM to 6 PM UTC+8 on weekdays), it might be challenging to catch the issue as it happens. Therefore, we suggest sending a print command whenever it's convenient for you, and sending us a private message right away so we can support you remotely.

Alternatively, we recommend upgrading to the official firmware scheduled for release next week, and observing if the issue reoccurs before proceeding with the remote access.

Please let us know your thoughts.

Hello @PimK82

We noticed that you've upgraded two APs to the latest official firmware. How has the performance been since the upgrade?

In case the issue reoccurs, we would like you to check the reboot sequence as follows:

1. Initially, reboot both APs and observe if this action resolves the printing task.
2. If the issue persists, please proceed to reboot the switch.

We look forward to your feedback.

Hello Pim,

Thanks for the update.

Regarding the reboot schedule feature, it has been supported recently when Nebula Phase 17.20 launched last week. Please find the FAQ here:
