GL MT6000 (v4.9.0 Stable) issues with Prolink Wifi Bulb

Just to check if it is a known bug whereby L2 Broadcast packets dropped silently between switch hardware (self) and software bridge (br-lan) on lan1 ? Basically I had this problem where my prolink wifi bulb is connected to a wired AP and it keep connecting (authenticated) every 20secs or so. Have queried on AI and it sort of identified it as some bug since packets were received at main router, GL MT6000, lan1 but not at br-lan, thus resulting the bulb not getting a proper IP address and shown as offline.

Thanks.

Hi

We don't believe we've encountered a similar issue before.

Could you please check the following?

  1. Besides the Prolink WiFi bulb, are other devices connected to this wired AP able to obtain an IP address via DHCP normally?
  2. Please export the router logs and capture packet traces on both lan1 and br-lan, then send them to us via private message so we can take a closer look.
