LAN port constant connect / disconnect


  • Aplifi HD, been running it for almost 2 years now. 3 mesh points as well. My LAN ports are connected as:

    1. iMac
    2. PC
    3. Xbox
    4. DVR home camera recorder

    Last week my iMac suddenly would start to disconnect, and then reconnect every 45 seconds. (wi-fi on iMac is OF3, I only use wired connection). It would reconnect, assign itself to the same address, and connect for about 45 seconds or so, and then disconnect for about 20 seconds, and reconnect. Never had an issue before, just happened out of nowhere.

    Thinking maybe it's the cable (not sure how they "go bad" but fine, I replace the cable. No improvement. I switch it from port #1 to port #2, and great, all is working fine.

    This morning I turn on the Xbox in port #3. And low and behold it is doing the exact same thing. Worked fine last night. Not today though. Disconnect, connect, disconnect, connect.

    So I switch #3 and #4. Wholla, all is good again.

    What is making these LAN ports suddenly stop working, and yet swapping devices make them work again?


  • @Devan-Kadwish This is strange behavior that I can't explain by just reading your description, but you can generate support files for us to review to try and identify what's exactly happening.


  • @Devan-Kadwish I'm having the same issue when it comes to disconnects and reconnecting on my LAN port.. I'll try swapping ports..

    Also, my wireless is stable there is no disconnects on wireless just LAN


  • I have a similar issue. I also had the intermittent connection/disconnects, but it has progressed to not working at all anymore.

    The last few months my ethernet port #4 has been unstable, and it died this weekend.
    Had my main PC connected there, moved it to port #3, instantly worked.
    Moved my Xbox to port #4 for verification, lost connection. Had to move it to my switch on port #2.
    Port #1 is also working.
    Should I expect the other ports to fail soon as well? Or is this a firmware issue?



  • @Thomas-Aasebø If the port does not work, (sounds like you have verified this by swapping devices) I would suggest submitting a warranty claim for your product.


  • As of today (apx 9 days since swapping) I haven't had any duplicate issues. So Im not able to run the diagnostic test as it's not duplicating the same problem. The port that was originally bad when it had the iMac in it, seems to be fine now that it has a DVR instead. The Xbox which stopped working on port 3 seems to be fine in port 2. Makes no sense.
    If it starts to reproduce itself again, I will keep the source connected and run the diagnostic as described.
