Connected to wifi, but no internet access
I believe you are going wrong here.

Why would you want to select 192.168.200.1 as DNS? It looks like a private IPv4 address, not a DNS address. Doing so, I believe you will fail to connect to internet.

In my experience DNS addresses have looked like 8.8.8.8 - like you mentioned, and 8.8.4.4.

You can try to use custom IP addresses like 192.168.200.1 keeping the DNS 8.8.8.8 or 8.8.4.4 only.
