In my instances. I've found bridged VLANs became unresponsive after the upgrade to 6.38.5. This was rectified by disabling rapid spanning tree protocol, and then re-enabling it to get the bridge to start parsing traffic again on 6.38.5. Take a look at the second topic comment made by 'bbs2web' as to a detailed explanation: https://forum.mikrotik.com/viewtopic.php?f=1&t=120946 Cheers Greg On 26/04/2017 7:11 AM, Alex Samad wrote:

This has bitten me on a few upgrade occasions(6.37.x>6.38.x).. There must have been an upset fan-base ?
***************** What's new in 6.39rc80 (2017-Apr-25 09:23):
!) bridge - reverted bridge BPDU processing back to pre-v6.38 behaviour; (v6.40 will have another separate VLAN-aware bridge implementation);
