Hi all,

Really hoping you can help me.

This afternoon all my devices connected via WiFi went "no internet"

All lights are on and router tests come back healthy.

Everything wired is fine and connected.

I did have an issue with WiFi and clicked on one of the settings shown above  (can't remember which one) and I lost everything.

out of desperation I factory reset the router and started again and as I wasn't sure how to reverse my selection (which made me lose internet via WiFi)

I am not even vaguely competent with home networking but at least I had it working before I went and meddled.

any help would be so gratefully received
