internet test.

[desert cloak]

Ok, I might be blind, dumb or both, but I cannot figure out how to start the internet test on the Switch.
Settings > internet > ???
There is no such thing as "internet test" in that section?
I can connect just fine at the wifi at home, but with other wifi or even with my phone's hotspot the Switch can connect to the device but not to the network.
All the guides suggest to run an "internet test" but I cannot figure out how to do so.
Thank you for any help.

'test connection'

@drifting ledge I have it only if I can connect to a wifi. My problem is that the Switch can connect to the network devices but not to the internet. It gives me different messages, either wrong DNS, weak signal, far from the device..even standing literally next to the device and with full wifi signal.
I have not this problem with the wifi at home though, just with two different wifis and with my phone's hotspot.

Try connecting to a network you know works and check if theres any system update

though it might just be the switch’s wifi being crap
