    Hi Zyxel Support

    I too, am experiencing these issues on the same router from Hiper. Since you said that I should not change the fw version, should I then not update it when the patch is released on June 17? Then what should I do.

    Hi danielnielsen,

    The patch with V5.13(AAVF.11)C0_20180409B is included in 13C0, you can use this one. But I suggest you can contact with your ISP first if it’s need do any settings for Hiper network.

    Dear Zyxel_Support_CPE,

    The download page[1] links to release notes for the latest firmware release. When I read the release notes[2] there is a section titled "Modifications in V5.13(AAVF.13)C0" on page 11, but nothing is mentioned about any 5Ghz issue.

    Are you an official Zyxel representative?
    Is this issue publicly acknowledged by Zyxel?

    Hi JustPretender,

    We did internal testing for a long time, can you please describe more detail you encounter in 13C0 fw?

    Hi thomaslkjeldsen,

     

    The solution was included in V5.13(AAVF.13)b1 version; you can refer to page 13 “5G beacon” issue.

    Great, thank you very much for pointing that out. I will upgrade to the latest firmware and see if that helps.

    Hi @Zyxel_Support_CPE the behaviour is EXACTLY the same as in my previous posts.

    I upgraded last week and since then the 5Ghz wifi has functioned as expected.

    Model Name: VMG3925-B10B
    Firmware Version: V5.13(AAVF.13)C0

    A few comments on the new admin UI.
    a) After login the load-spinner disappears but it still takes 1-2 seconds before the UI finishes loading data into the boxes titled "Connectivity", "WiFi Settings" etc. Meanwhile the default values are displayed indicating no internet connection, wifi disabled. Consider keeping the load-spinner active until data is ready for the boxes.
    b) I can't remember where but I noticed one or two pages where it was not possible to scroll down to the bottom, and the only way to see the last fields at the bottom was to zoom-out (cmd-minus).

    However, overall this firmware looks like a good upgrade. Thanks!

    Hi JustPretender,


    Which 5G channel is used when the issue happens? You can login to device and then go to Network Setting> Wireless > General > select Band “5G” to check it.

    In order to clarify if it’s caused by radar signal, can you please help to select channel to ch36/40/44/48 to monitor?

    My last comment got deleted and/or hasn't been approved (edited it a few times which resulted in some spam protection), but after upgrading to .13 version yesterday, selecting an appropriate wifi channel (currently 100) and giving the modem a minute or two to do it's scanning that is apparently required by regulations/standards, I have now had the 5GHz network up without issues.

    I noticed that on lower channels, 36-48, there's so much interference with other wifi networks that my 5GHz network would not work at the other end of my apartment even though I got a signal.

    So, anyone who has had issues with the 5GHz network, give the modem some time, 1-10 minutes, before judging if the network is working or not. And, check with some wifi analyzer software how crowded your area is between channels and change it accordingly.

    But for now, whatever issues there were, they seem to have been fixed.
