GL-AR750s tethering:"no internet"

I’m trying to tether my Galaxy A20 to a GL-AR750s and when I connect my laptops to the router wireless or via the supplied Ethernet cord it connects but there is no internet. I get the “no internet, secured” message. Does this thing tether or not? I can tether directly to my laptops but not to this. Suggestions?

The router successfully get IP address from your Galaxy?
