    Dear Merlin and experts,

    I have been using your firmware for years now.
    Since today I have a very odd problem.

    My asus RT-AC88U with Firmware Version:384.17 is my main Router.
    Asus RT-AC66U X 2 are on AP mode.

    Since today my internet disconnects with all my 5 D'link switches (tested each one seperatly to rules out a broken one)

    First i reset my main router and disconnect all other AP's and switches.
    Then Main router is back online, i plug in cable to D'link switch (tried every lan port on router and switch) and my internet is gone.

    Well i found that out after hours searching.
    Then i put a netgear switch behind my main router and my internet/network is back.

    So i start buidling up my AP's and switches.

    AP's all work and still have my network/internet so am glad but....

    From the moment i connect one D'link switch the internet/network disconnects.

    I have never seen a problem like this.

    Do you know or any else what the problem can be?

    Thx in Advanced
