WIFI refuses to connect to public account

[tkocou]

My laptop connects to my home router, so the software is functional. I went to a restaurant and attempted to connect to their password protected guest account. The manager gave me the password, but for whatever reason, the laptop refused to establish a connection. My android phone had no problem connecting to that same router. So the router is functional.

Any suggestions on what to check?

See the post by "Mandywins". For additional information, see the entire thread.

Also check apt policy network-manager-config-connectivity-ubuntu. If that is not installed then you lose the ability of network manager to detect captive portals.

Thank you for the link. It was very informative. I've modified the NetworkManager entry for the restaurant wifi along with using dnsmasq. I'll report back once I try this modified connection.
