my wireless devices won't connect to my time capsule network.
I recently switched to comcast and have an Arris TM822 cable modem. the wireless network was working fine with my AT&T equipment, but now it doesn't. All lights are green on the devices and my iphone picks up the network name, but it will not connect to the network to allow using the wifi signal instead of 4G or LTE signals. The connections are in the following order: internet cable to Arris modem to Time Capsule to iMac. The computer has an internet connection and shows the wifi signal. I've tried all of the reset options, but maybe I need to switch some of the settings? And, of course, Apple won't walk me through it again like they did before unless I pay. HELP!!
