I play super Smash Bros Ultimate but I just moved to University. I have to download an authenticator app on my phone/computer to connect to the main network which is not available on the switch. I have to connect to their weird secondary network with it. Due to this, every online game I try to connect to I cannot connect to the other console(s). I just got back the IT person and they told me that it is probably due to the restricted NAT type, they are not going to change it for me (understandable). But I would still like to play with my friends online. Is it possible, to run an ethernet from my desktop computer to my Nintendo Switch in order to connect it to the main network with an open NAT? (I can connect to games just fine on my desktop computer). I am currently using a Wifi card on my computer to connect to the internet, can I use the open ethernet on the mobo? Thank you for any help!
