Hi gurus, we have a full WLAN deployed in various floors of our building, by using Meraki MR42 APs.   For auth purposes we uses Enterprise with my Radius Server. Radius is a Windows NPS and validates users in a Windows Domain controller...   The user IP is provided by a DHCP server in the same subnet as the users connect when uses the WLAN.   Everything work fine, EXEPT when a user moves from one floor to another and come back. I mean when a user take its mobile computer and goes to a different floor (and roams and connects to a different AP) and return to its original place (supposed to roam again and connect back to the original AP)   In that case, the mobile computer is disconnected completly from the WLAN. Nothing work again up to the user turn its WiFi off and reset it.   Its work as well if the user has a mobile wifi setting called "random hardware address" on, but this setting is not existing in all mobiles.   Any ideas of how can we solve that..? why this behaviour..?   Thanks a lot for your support. Regards.   ... View more
