Hi @cmr , all APs are MR18 on version 25.11 last upgraded on the 7th of May 2018. I doubt a software update on the clients is causing the issue, as we have tested with a few mobile devices (both android and apple), 2 windows laptops and a Mac and all of them were having the same issue. I am leaning towards upgrading the APs to a newer version. What are your thoughts on the stable release candidate? Is it a stable enough release that we can upgrade to or it would be wiser to stick with the Stable release of MR 25.13?

Hi @cmr We performed the wired test as you suggested. We connected a laptop to one of our switches and changed the vlan to make the host in the same network as the Wireless devices and we did not observe the issue. I think we can conclude that the issue appears to be only when on Wireless connection. Is there anything else you recommend we can change (configuration wise), in order to try and fix the issue or is upgrade going to be the next step? Regards, Desislav

Hi, Thank you for your reply! Connecting a PC with a cable to the same subnet is some I was going to test later today. I do not see how the Firewall can be causing the issue is our case, as it is passing the traffic from the Wireless without inspecting it, the policy allows any destination and port. The idea is to have an unrestricted network with full access to the internet for testing purposes. The Current version on the APs is: MR 25.11 .

Hi everyone, We are having quite a strange issue with our company setup and Meraki Access Points that we can't get find a fix for and I am hoping that some of the experts here can give us some fresh ideas and advises on how to tackle it. In our office, we have 4 Meraki access points that spaced out throughout the office to provide full coverage. Our development and QA team are connecting to the company wireless and performing various test using Geoedge VPN to hop from location to location. Since about a month ago the VPN started disconnecting them frequently and some times they are completely unable to connect to any location. At first, we thought that the problem is with the VPN client itself, so we moved a few devices to mobile hot spots using the telephone providers mobile network. While on the mobile hot spot, the frequent VPN disconnections and inability to connect to the different locations is no longer observed. Our company Firewalls are set up to permit the traffic from the APs to any destination and any port without restrictions. The APs are setup in bridge mode, so the Firewall is assigning the IP addresses to the hosts that connect and the only layer 3 firewall rule that we have set up on the AP is to block peer-to-peer connections. As a test, I created a new SSID that has the Meraki to performing the DHCP IP assignment and with the layer 3 firewall rule to block destination "Local LAN". With this setup, the users connecting to the Wireless are assigned random IP address and have no LAN connection to one another, however, upon testing, we are still seeing the same behaviour with a slight improvement(the VPN disconnections are not happening as often). During all tests, I've had a constant ping from one of the hosts to the AP to which it is connected and there aren't any packets dropped. Some of the devices we are testing this behaviour with are connected to different APs in the office but on the same TEST SSID. We have not ruled out the possibility that the VPN client or/and the servers we are trying to connect are causing the issue, but since we do not observe this issue while connected to a mobile hotspot, we have our doubts at the Meraki AP at the moment. I would appreciate any suggestions/advises on what else we can do from Meraki point of view, to further troubleshoot the issue and hopefully fix it. Thanks, Desislav
