Thank you all, Monday we have a TAC session between 3 and 4 and will share their findings.  for today i turned off a second SSID we were setting up for EAPTLS with corporate laptops and the other guest internet SSID suddenly started working!!  so currently no device roaming, no drops and all looks good.  TAC have also admitted there is a separate ongoing investigation into the CW9176I ap due to customer issues.  ...

Morning all   just to share TAC involved now for a while and the vendor sent me the below last night, matches a comment above from Bikram   One additional recommendation from TAC, based on similar customer environments, is to disable 802.11r when WPA3 is enabled. Fast roaming features such as 802.11r can conflict with WPA3’s mandatory 802.11w settings, particularly on the CW9176 platform.   Although not officially confirmed, the Meraki engineering team is aware of roaming issues on CW9176 that appear to be linked to WPA3. Given the similarities between our case and the scenario under investigation, we requested that our case be associated with the internal engineering ticket. However, TAC could not confirm whether our situation is an exact match (of course I understand they are relaying on matching logs). We are pushing TAC and have asked TAC to maintain the case at Severity 1.   ... View more
