something like this interesting. Its cheap, runs on USB power and can do quite a bit. I use mine to create a wireless LAN, that I put my media server on - From there, I associate with my laptop and can stream movies and television until my heart is content. Usually about 30 minutes.
I could, if I wanted, have the mini router associate with another 802.11x network such as Starlink, making everything connect beautifully. There are severl other similar models available, this is just the one I settled on becuase of its size.
My media server is something I talked about, and it started out as a project here -- but it got really technical fast, and I kind of stopped developng the documentation -- it was moderately difficult for me, but I quickly realized that for 9 out of 10 people -- it was just out of reach. When you star talking RaspberryPI, Plex (now emby), router configuration - I was losing my audience. But, if anyone is interested,
we can pick that back up in its original thread.
