In any case, my wallet held about 13 connections only. standard 9 inputs and 13 outputs. And I would like to connect to more nodes.
Outgoing connections are where you are retrieving blockchain information from... these are the only connections that you can "force" (using "addnode")
Incoming connections are where other nodes are connecting to you, to retrieve blockchain information. You cannot really do much to influence this value, other than allowing incoming connections and possibly setting the "maxconnections" value to something large... although this defaults to 125... "-maxconnections=<n> Maintain at most <n> connections to peers (default: 125)", so if you're only getting 9 incoming, then changing this value won't change much.
You cannot force other nodes to connect to you, and they're likely to prioritise connections based on latency etc... so if there aren't a lot of nodes "near" you (from a network latency perspective) then chances are you won't see many incoming connections.
Just leave your node running with allow incoming connections... people will use it, or not... there isn't much you can do.
Why do you care how many nodes connect to you anyway?
