That's correct. They are internal on this model. Even if they were external, I still want my wifi network, just not the public hotspot so disabling all wifi wouldn't help.
All I see under the title "Notepad++ 6.7.9 release" is a direct link to download the source code and a link to download the binaries from their site. It seems like they should be directly linking to their website from the sourceforge page.
Looks like the SourceForge n++ page is still there(http://sourceforge.net/projects/notepad-plus/), but downloads have been removed. I find it interesting that they're directing people to their github page and not their website. Considering that users are going to sourceforge to download the application, not build it from source.
