Anyone here have any home level networking tinker experience?

I’ve got most of that kit and have the network drive attached to the modem/wifi router set as a media server? Really no expert, but you should be able to get all of them to talk to each other as an ad-hoc network without the wifi modem (I think. Experts here will tell me if this is wrong!)

What did you have in mind? Media server for movies anywhere? Retro gaming laptop? Something more nuts-and-bolts?
