I ran into a similar problem when I installed the (second) named instance of SQL Server (2016). The default instance also runs on SQL Server 2016.
2 things to check:
If you installed a 64-bit SQL server, the section "SQL Network Configuration (32-bit)" will be empty. You will have to check in the section "SQL Network Configuration" --- (without specifying 32-bit)
In my case, "SQL Network Configuration" --- (without specifying the 32-bit version) did not appear as an option. I could only see "SQL Network Configuration (32-bit)", which was empty, and "SQL Network Configuration" was missing. I did some research, and then realized that the SQL Server 2017 instance was previously hosted on this server, which was deleted, after which 2 X 2016 instances were installed. The server still had 2017 components, such as SSMS (sql server management studio ), sscm (sql server configuration manager), etc. I opened SQL Server 2017 Server Configuration Manager, where my instances run on SQL Server 2016. Later I manually opened SQL Server Configuration Manager (2016), which had SQL Network Configuration, as expected.
Hope this helps.
