Hello,   I migrated from a 64 to a 67.  The migration took 5 minutes, SSIDs carried over, everything connected just fine.  The only issue I am having is with my sonos speakers and application.  The speakers are connected via WIFI.   Upon using the SONOS app on smartphone or the pc that is hard wired in, it is laggy selected songs and sometimes disconnects from the speakers all together.  The issue only surfaced after making the MX swap.  Before that everything was working fine on the MX64W.   - Have rebooted everything.   - Have added in QoS priority for music.   - Have white listed SONOS speakers.   - Have disabled Umbrella integration in hopes that it was maybe a DNS issue.   - Have rebooted everything. Routers, MX, speakers.   - Have checked for duplicate IP addresses.   - Have enabled speed burst.   At this point I am running out of ideas.  Anyone have any suggestion?  I know this is pinpointed to the MX64W to MX67W swap but I am not sure what else there is to do.  Any thoughts?     ...
