Hi Community: I'm confused with an implementation   I will explain: There are two offices located on different floors of the same building. One of them has 3 AP (1MR18 and 2MR42) and the superior one with 1 AP (MR33) since the area is smaller. The problem is that from the top floor to the bottom there are no problems with roaming, nor access to the wireless network (authentication with 802.1X RADIUS in one SSID and WPA2-PSK in another), however from the bottom floor to the top, the connection in the client shows "error getting IP address" (for both SSIDs) and the logs in Meraki are:   All APs are in the same subnet and all have their trunk port for all VLANs as well as untagged for the IPs from which they are handled. It should be added that if the MR33 is rebooted then there is no problem to access the wireless in the upper floor, but once the client leaves the coverage of the MR33 for any other AP and then returns again, then gets "error in IP" . The APs use different channels in 2,4 band (1,6,11 for the lower floor and 1 for the upper floor, which in turn is the furthest from the other that uses channel 1) and also in 5 band.   Any ideas about what could be wrong? Any suggestion?   Thanks in advance ... View more
