It seems to be a DNS issue if pinging 1.1.1.1 works. On your laptop or MacBook, run the nslookup command for “google.com” to see if the domain can be resolved.
If it does not resolve, then log into the router over SSH and run the same “nslookup” command. If it still does not resolve, then check/reconfigure the DNS settings on the router.
I do not work for and I do not have formal association with GL.iNet.
