      wlc_tx_fifo_sync_complete

      Hello.

      Replaced my SR203 router with AX86U and add a Draytek 166 for my GFast plus a pair of ZenWiFi AX in AiMesh mode backhaul mode ON.


      The Asus router was flashed with the Merlin 386.1_beta3 and beta4


      After rolling back the firmware the device was factory reset and reconfigured from scratch.


      A Cisco Meraki switch MS120-8LP with RSTP enabled handles more of my wired connections.


      Connection was stablished fine but the issue I am having is that randomly all devices disconnect from the internet for a few seconds and reconnect again.


      Have seen this while playing online and during Teams/Zoom meetings as the session seems to stop ( I can continue listening to the other people during the meeting but they cant) and then when I reconnect works like nothing happened. But it happens constantly.


      Checking the time logs of these dropouts the following is reported:

      Jan 19 15:44:52 kernel: CONSOLE: 302384.847 MQ: wlc_tx_fifo_sync_complete: fifo 4: collected 2 pkts

      My Linux is no way my strong point, any idea what this means?

      Have attached a syslog as well.

      Thanks,
      H

      Re: wlc_tx_fifo_sync_complete

      Hi again,
      It turns out that the MTU was the main reason of my issue..
      Draytek 166 (UK) comes with a default MTU of 1520 (at least mine - brand new) = had to reduce this to 1500.
      My Asus Merlin MTU had to be tweaked to 1508 - after that no more packets loss.

      Hope that helps someone...
      Cheers
