Since converting my home WiFi to a mesh with Deco X20, everything is fine, except my iPad 3rd Gen will not, or cannot connect to the internet. Is this a problem with the network or the iPad? Thanks...

@TP-Link Thank you for your response. Being new to Deco, it took me awhile to simply find the Guest on-off switch. Turning it on solved my problem.

Installed AX1800 Whole Mesh Home System with 3 Deco X20 units. Had no problems installing, good results with the new network. However when trying the Guest network, it says "no internet connection"....
