I'm trying to set up two CPE210s as an AP and client to get wifi to a remote garage (outdoor distance between AP and client is about 100 feet).

Router------>AP  -    -    -    Client------>wifi router   -    -    -    (smart garage door opener, etc.)

I configured and installed both the AP and client; they're talking, and there's internet from my router to the AP.  But I can't connect to the internet from the client.  I tried connecting a wifi router to the client; no internet.  I then tried to troubleshoot by connecting a laptop to the client via ethernet.  IPv4 connectivity says "No network access," and IPv6 connectivity says "No Internet access."

Seems to be a configuration issue with the client?  What have I done wrong here?  TIA.
