Difficulty with iCloud verificiation over home wifi

I'm having a very confusing issue with my daughter's iTouch6 and my other daughter's iPhone5s when they are on our home wifi network. Both machines can't send or receive images on iMessage and both have verification errors when logging into iCloud. Other uses of wifi seem to work ok (regular text-only messages, using Safari, etc.). All functionality is fine on my wife's iPhone6 Plus and my iPhone6 using the same wifi network. I've tried resetting network settings. I've tried restoring the iTouch as a fresh machine. I've tried a few other solutions found online to no avail. The problems persist so long as they are on the home network. As soon as I tether them to my iPhone and use cell connection (not wifi) they work fine.

Anyone have any ideas?

iPod touch, iOS 9.3.1

Good thought. The old router was a Netgear Nighthawk (they screwed up a good router with a buggy firmware upgrade and didn't fix it for 6+ months. I moved on from Netgear) and didn't have these problems. I will read that link and see if I need to open specific ports or such. Haven't been home to try it and it may be a while until I can. I will report back when I do. Thank you for your ideas.

Tried (a) port forwarding for port 80, (b) monitoring QoS traffic (the monitor just shows some activity and not specific details about the activity, and (c) just turning off the firewall completely. Nothing had any effect on my ability to login on icloud or imessage on the offending itouch. All other apple devices in the house working fine except for one other iphone5s with the cell service turned off (ie wifi only). anyone have any other ideas to try?

OK. Now the plot has thickened. I put one of the problem devices (iTouch) on the 2.4 ghz Guest wifi and it now works! Connects to iCloud/iMessage no problem. However, this trick does not work for the other problem device (an iPhone 5s with cell service turned off). Anyone know how a guest wifi differs from the regular wifi and why this makes a difference with iCloud? Secondly, why would it work for one device and not the other?
