Steam Link has been around much longer and if you trust Valve to keep their software up to date chances are it’ll work at parity or better than Moonlight.
They would likely be forced to build more infrastructure to support the increased demand. Boo hoo spending on infrastructure instead of c-level pockets.
It supports wifi and usb, that’s what it says in the description of the app.
If you’re looking for a solution that requires no ‘sketchy’ client, this supports rtsp and a few other protocols.
Works with obs virtual cam really well
I have mine setup on a Supermicro itx-based machine with an Intel n3710 and 8G of RAM. It has four Intel-based ports but you can easily get away with two.
I used to run a Zotac ci323 with dual Realtek nics. Works fine for 300M up/down.
You’ll want two ports, one for WAN one for LAN and most nics will support VLANs if you need more than that.
Any VPN or encryption will increase your cpu requirements. If your needs are low a cheap dual-nic Nuc like device works great.
