    I have this extremely annoying thing where my router keeps dropping all my wifi devices for a few seconds then reconnects again.

    Jan 12 22:55:58 WLCEVENTD: eth1: Assoc 00:7E:56:77:30:11



    This is what shows up in the logs. Every single homekit devices resets at this point, lights turn on (the default state) and homekit outlets reset, turning off and on (no idea why they turn off but whatever). Its really annoying, had this router for about 1 year and didn't have any problems with it..it just started doing this sh*t few weeks ago.

    Anyone else knows whats up with these WLCEVENTD events? and how can they be fixed?

    Thank you...Asus has sh*tty support so I have no luck with them besides sending this to warranty and waiting 2 weeks to prob get it back.

    I went with Merlin Firmware after this and its good, no more drops for 1 week since I have it. I recommend changing the firmware.

    I had to roll back all my routers.

    This firmware version does not work.

    All my RT-AC86U units have the same issue.

    Did we do the testing on this firmware?

    Are you using Merlin Firmware too? I had the issue with latest stock Asus firmware but its all good after I changed it. I posted this on Asus forums too and sent it to support but not even a reply from them...

    And issue on my AC86U on the Merlin 384.9 firmware. Very annoying when watching a movie on Plex. Video would stop every 10 min. Had to roll back to the previous firmware version.

    I had this problem where my (AC3100 ver. 3.0.0.4.384_45149) WiFi devices on the 2.4Ghz band (e.g. Wemo, Home Kit, Google Home minis) were NOT connecting after I restarted my router. The router's log was full of repetitive error entries for those unconnected WiFi devices - WLCEVENTD: Disassoc and Assoc

    I was able to RESOLVE this issue by disabling the Airtime Fairness and Universal Beamforming feature in the router:

    • Log into the router as the administrator
    • Select within the left pane menu: Advanced Settings > Wireless
    • Select along the top tabs: Professional
    • Select the Wifi Band (drop down menu: 2.4Ghz) having the issue
    • Set the following 2 features to Disable:
    1. Airtime Fairness
    2. Universal Beamforming
    • Click on the Apply button to save the settings
    After making the above changes, all my 2.4Ghz devices reconnect within 2 mins. after a router reboot (I have 15 devices on the 2.4Ghz band) and I no longer get those Disassoc/Assoc error messages in the router's log. Note that I did NOT experience this problem with devices on the 5Ghz band.

    Thanks! I started to have issues again even with Merlin Firmware and it happened more and more often...I disabled the stuff and I hope it will get better now. I had only the Universal Beamforming enabled.

    I do not have Homekit or Wemo devices, but I get the impression that the way they use multicasting might not work well with Asus router defaults. If this is the case, then you could try the following:
    • LAN > IPTV > Enable multicast routing (IGMP Proxy) > Enable
    • Wireless > Professional > Enable IGMP Snooping > Enable
