You do what now? Yes you can use a 5G connection with it, I don’t believe it has a modem which is what I think you need to replace. Most likely you’d have to call your ISP and register a new modem anyway Sierra Wireless Cradle point Etc. Probably something you’d have to be on a business account to do though. I would buy a cheap 5G Android phone and Root and Magisk then dialup using tether in openwrt
I’ve played on Ephinea, it’s a pretty good experience. Afaik there’s not a good way to play on mobile except Steam Deck or other expensive hardware, if net play worked on the Android version of dolphin that would be massive (it won’t probably also only be a matter of hours before Nintendo got butthurt) If there were a larger player base or they could make more changes to the game I’d definitely play more.
