According to my connection test, it’s currently at 18Mbps download and 667.5Kbps But, to be fair, I’m streaming on the Chromecast right now so the internet’s probably pretty busy...
Mine said 18.6 Mbps down, 1.5 Mbps up. Other than having ACNH suspended on it atm and not being literate in good download/upload speeds, that sounds about normal. Actually, considering the wifi in general here at my parents' house, my Switch (Lite) generally has decent connection abilities. I will have the connection suddenly drop when my gates have been open a long time on occasion, but thankfully that's never been when I had anyone over.
My phone, on the other hand, flips back and forth between wifi and data at least once a minute because it can't get a stable connection on either
