If it's just plug and play and works well, it'd be brilliant. I have experimented a lot with a couple or wifi dongles I had lying around and setting up a hotspot, but honestly I could never get it to work well.

Streaming VR content is just so sensitive. I have a good cabled network but even a simple switch introduced noticeable lag spikes. In the end I have a separate router that I just connect straight to my PC, and then I share my wifi connection through my PC to that network. A whole silly setup just to minimize latency and packet loss. If that could be replaced with a simple USB dongle I'd be amazed.
