Hi everyone, I just deployed a Meraki network in a residential building in which our company provides wifi to tenant units. The building has 108 apartments, so I though it would be a perfect opportunity to deploy our first environment in which we use greater that 50 PSKs (1 for each unit). The general theory is that we've built a /24 subnet for each apartment, tied to a group policy with VLAN tagging for that particular subnet, and a unique PSK to connect to the single SSID. Each unique PSK will place tenants in their correct group policy, and subnet. At first, we did not enable WPN, as we had a subnet for each tenant, and a group policy pointing towards it, so no need for it right - the group policy should take care of everything?? Not quite. During the deployment, we had a lot of trouble with Access Points randomly restarting, and dropping off the network. When we turned off all broadcasting, things went back to normal. As soon as we turned on the SSID with the PSK environment, back to APs dropping. Turns out, if you are using more than 50 PSKs in a GP environment, WPN HAS to be turned on. As soon as that setting was enabled, everything went back to normal. We have another property with 48 units (48 PSKs) and WPN does NOT need to be on for things to perform normally. Interesting. This was not plainly expressed in the config guide so I just thought I'd share my experience, to save someone else a headache in the future. I know WPN and >50PSK is rather new, and required 29.1 or greater firmware, so things may change going forward. Has anyone else had a similar experience?
