Wireless connectivity issue after new Airport Extreme
I have an older Time Capsule and recently bought a new Airport Extreme to "replace" it as my main wireless hub. I currently have an Express which extends the network, and am attempting to use all three to extend the network further. Extreme as the main hub, with the other two extending the network. I have Comcast.
After plugging in the Extreme, all show that they are connected. However, no wireless devices are able to connect. I have rebooted everything several times to no success. After rebooting, connectivity lasts approximately 2-3 minutes.
Anything I can do?
MacBook Pro (13-inch Early 2011), iOS 8.2
