Yes we have tried swapping out the AP but we see the issue with multiple users on different APs so at this point I'm not sure it's hardware related, but could well be firmware. However to date Meraki haven't suggested this and we still see the issue after multimple firmware upgrades this year.

Hi All, I'm hoping somebody has had this issue and found a workaround. Intermittently certain users get disconnected from the wifi for upto a minute. By disconnection I mean they have full signal but a yellow exclamation mark (windows 7 64-bit) Intel and Broadcom Nics. We use WAP2 802.11x for authentication using machine certificate. These users tend to be static in the way that they haven't moved from their desk. If you do catch it when it happens you effectively cannot ping the gateway by ip or hostname, DHCP on client looks to be in tact with the user having the correct IP, S/N, G/W and DNS. Other clients are connected and working on the same AP during this clients disconnection In terms of setup we have 802.11 trunk between APs and Cisco 3850 Stacks Native VLAN carries corporate data (the network we experience the disconnects/ yellow triangle on) Separate VLAN for Guest Internet Separate VLAN for Corporate Mobiles This is what I have looked at- There is nothing in the Meraki logs to show a disconnection, roam to another AP, generally all I see is the user connect in the morning and then disconnect when they leave. There is nothing in the event logs on the laptop to show any form of disconnection There is nothing in the intel advanced logging to show a disconnection. Power settings on wifi nic are correct All power saving removed. We have completed RF surveys at all of our sites and tuned channel and power accordingly- this hasn't made a difference. Radius logs have been checked and again no errors there. Monitoring of the actual APs shows no drops in connectivity Switch interfaces showing correct speed and duplex Switch interface stats look good No other LAN related issues are currently being experieinced DHCP and DNS Servers look to be behaving with no errors in the event logs. I have logged this with Meraki several times now and don't seem to be getting anywhere. If anybody has had any experience of this or can think of anything else we can try I would appreciate it.
