    Hi to all
    I have some trouble with router freshly bought, unpack and setting.

    The symptom is always the same, arrived at one hour of used, my ChromeCast was disconnected. No ping works.
    Acting on the Asus Wifi Box, like making Wifi change, to ask to the Wifi Box to restart Wifi services, the ChromeCast is accessible again for one hour.

    What i have already done:
    - Cold Restart
    - Defaut Setting and cold restart
    - Upgrading firmware
    - Downgrading firmware
    - Upgrading beta version firmware, (to get Wifi Insight reports)

    I looking for about settings should close to 3600 sec like the Wifi security keys rotations. Disable Wifi Trame Power Save, set to 0.

    I activated the SmartConnect function, in the case of bad Wifi signal, and helping device to switch to 2GHz in case of.
    With Wifi Insight network tools, ChromeCast was connected in 5GHz with a signal quality at -77/71 DBm.

    So now, HELP !
    :)

    Unfortunately, I cannot add anything more to help but I did contact ASUS support as my RT-AX88U has been having the same issues with my Chromecasts as well as auto-rebooting and dropping the 2.4GHz. After doing the recommended rescue (https://www.asus.com/support/FAQ/1000814/) the rebooting and 2.4GHz dropping has seemed to stop but the Chromecasts still don't show up to cast and their settings are unavailable in the Home app even though the router shows them connected. After changing the Preamble Type from Short to Long they worked for a few hours but this morning are not castable even though again the router shows them connected. ASUS support has authorized a repair/replacement under warranty and I am waiting to hear back on stock for an advanced replacement. They collected amble logs and configuration files from me and concluded the hardware needed replacing. I'll report back if/when I ever get this new hardware.

    No compliance with ChromeCast, confirm by Google Support. I have returned the Asus....

    Chromecast has issues with Airplay Fairness setting. Turn that off and you should be good.

    My Shield TV works fine but it's hardwired to the router, the first and 2nd gen Chromecasts are giving me trouble but worked perfectly on my RT-AC88U. I'll see what if anything the replacement RT-AX88U does but I might just have to pull out the reliable RT-AC88U again.
