I just switched over to a new network, utilizing MX68 Meraki. The ISP has already plugged their Wan interface into the Wan interface of my Meraki and everything is already configured on the backend of my Cisco cloud. I was able to switch most of the devices over to the new network and its SSID successfully but I still have a few different devices that will not connect to this new network. These aren't any special devices, like a printer and a couple of handheld devices. The old router is unplugged as well but, I can still see the SSID broadcasted in the network settings of the computer but only 1 bar and not 3(shouldn't be showing at all once I powered off the old router). What exactly could be causing these few devices to not connect?
