Device connectivity issues with running bridger on RT3200

[graysky2]

If I boot my RT3200 with the following in /etc/modules.d/mt7915e: mt7915e wed_enable=Y and with bridger enabled, some connected devices no longer detect a routable internet despite being connected to the SSID.

This particular device is configured to be a dumb AP and is configured with VLANs if that makes a difference. Happy to provide any config or debug files to help troubleshoot. I see nothing in dmesg nor in the output of logread

What devices are you having issues with?

Initially it was just a single ipad air 2 but more recently, something crashed on the RT3200 itself which took down all of the SIDDs on my 5 GHz radio. Required a reboot to recover. All I could see for debugging were these lines from dmesg:

[58088.418578] mt7915e 0000:01:00.0: Message 000026ed (seq 3) timeout

@nbd168 - I am not totally sure that the problem I encountered is due to bridger.

I left bridger installed but disabled it yet I kept options mt7915e wed_enable=Y in my /etc/modules.conf. I encountered a very similar loss of WiFi:

• Only one of my 3 SSIDs was visible
• Devices could not connect to it

I found this in dmesg:
