Hello, My school has 32 MR33 access points deployed. We have had basically 0 problems with them since we installed them a year or two ago. However, when I upgraded our firmware to 26.6.1 on 2/11 at 7PM EST, we started to notice that our Brother HL-2270DW printers lose and regain connectivity over and over. This is impacting no other devices on our network - only these printers. We have about 8 of them. They are all experiencing the same exact issue, and they all started doing so right after the firmware upgrade. Here is a little snippet of what one of them is doing from the event logs: Mar 4 11:39:14 Room319 7HillsChartN BRN001BA9BED9F1 802.11 disassociation unknown reason Mar 4 11:39:14 Room319 7HillsChartN BRN001BA9BED9F1 WPA deauthentication radio: 0, vap: 0, client_mac: 00:80:92:7D:05:22 more » Mar 4 11:37:31 Room319 7HillsChartN BRN001BA9BED9F1 WPA authentication Mar 4 11:37:31 Room319 7HillsChartN BRN001BA9BED9F1 WPA deauthentication radio: 0, vap: 0, client_mac: 00:80:92:7D:05:22 more » Mar 4 11:37:31 Room319 7HillsChartN BRN001BA9BED9F1 802.11 association channel: 1, rssi: 55 Mar 4 11:37:17 Room319 7HillsChartN BRN001BA9BED9F1 802.11 disassociation client has left AP Mar 4 11:37:13 Room319 7HillsChartN BRN001BA9BED9F1 802.11 association channel: 1, rssi: 57 Mar 4 11:37:09 Room319 7HillsChartN BRN001BA9BED9F1 802.11 disassociation unknown reason Mar 4 11:37:09 Room319 7HillsChartN BRN001BA9BED9F1 WPA deauthentication radio: 0, vap: 0, client_mac: 00:80:92:7D:05:22 more » Mar 4 11:22:57 Room417 7HillsChartN BRN001BA9BED9F1 802.11 disassociation client has left AP Mar 4 11:22:57 Room417 7HillsChartN BRN001BA9BED9F1 WPA deauthentication radio: 0, vap: 0, client_mac: 00:80:92:7D:05:22 more » Mar 4 11:22:48 Room319 7HillsChartN BRN001BA9BED9F1 WPA authentication Mar 4 11:22:47 Room319 7HillsChartN BRN001BA9BED9F1 WPA deauthentication radio: 0, vap: 0, client_mac: 00:80:92:7D:05:22 more » Mar 4 11:22:47 Room319 7HillsChartN BRN001BA9BED9F1 802.11 association channel: 1, rssi: 57 Mar 4 11:22:45 Room417 7HillsChartN BRN001BA9BED9F1 WPA authentication Mar 4 11:22:45 Room417 7HillsChartN BRN001BA9BED9F1 802.11 association channel: 11, rssi: 33 Mar 4 11:22:31 Room319 7HillsChartN BRN001BA9BED9F1 802.11 disassociation client has left AP Mar 4 11:22:31 Room319 7HillsChartN BRN001BA9BED9F1 WPA deauthentication radio: 0, vap: 0, client_mac: 00:80:92:7D:05:22 more » Mar 4 11:22:30 Room319 7HillsChartN BRN001BA9BED9F1 802.11 association channel: 1, rssi: 58 Mar 4 11:22:26 Room319 7HillsChartN BRN001BA9BED9F1 802.11 disassociation client not authenticated Mar 4 11:22:26 Room319 7HillsChartN BRN001BA9BED9F1 802.11 disassociation client not authenticated Mar 4 11:22:19 Room319 7HillsChartN BRN001BA9BED9F1 802.11 disassociation unknown reason Mar 4 11:22:19 Room319 7HillsChartN BRN001BA9BED9F1 WPA deauthentication radio: 0, vap: 0, client_mac: 00:80:92:7D:05:22 more » Mar 4 11:16:20 Room319 7HillsChartN BRN001BA9BED9F1 WPA authentication Mar 4 11:16:19 Room319 7HillsChartN BRN001BA9BED9F1 WPA deauthentication radio: 0, vap: 0, client_mac: 00:80:92:7D:05:22 more » Mar 4 11:16:19 Room319 7HillsChartN BRN001BA9BED9F1 802.11 association channel: 1, rssi: 54 Mar 4 11:16:18 Room319 7HillsChartN BRN001BA9BED9F1 802.11 disassociation unknown reason Mar 4 11:02:21 Room319 7HillsChartN BRN001BA9BED9F1 WPA authentication Mar 4 11:02:21 Room319 7HillsChartN BRN001BA9BED9F1 802.11 association channel: 1, rssi: 56 Mar 4 11:02:20 Room417 7HillsChartN BRN001BA9BED9F1 802.11 disassociation client has left AP I have tried changing them to DHCP, back to static, reset network settings and rejoined wifi, updated the firmware of the printer to the latest version, etc. No matter what I do, they will be connected ok for a couple minutes, then be disconnected for about 5-7 minutes, then regain connectivity for a couple minutes, over and over and over. I would roll back the Meraki firmware, but we are now past the 2 week window. Again, the only thing that has changed was the firmware upgrade. The printers, location of the printers, settings, etc. are all the same when they had stable connections before 2/11. Any ideas would be greatly appreciated. Thanks!
