I did it. I use Ethernet Adapter Lan to Usb (Ugreen 20253- Chipset AX88772A) to connect Lan for my Wii U. Are you using a wireless or wired connection?
Sorry for my poor English, I'm from Vietnam
I may try the new ram site, and download more RAM to my Switch. Not sure if ddr3 is the right ram
for it tho. Edit- no it uses floppy Ram, just like @AncientBoi
