There just doesn’t seem to be a market for 5G Ethernet modems domestically. Everybody seems to be gravitating towards 5G routers and “Hubs” in the residential space.

If your router supports it, you’ll have better luck with a USB dongle over an Ethernet modem.

I only use my desktop for gaming now but it’s old and won’t run Win11. I’m going for a SteamOS general release then I’ll just drop windows on there altogether

That was the purpose of MirrorLink, but I think it’s dead now. I only ever saw Volkswagen support it.
