Nintendo Switch won’t connect to Wi-Fi. How can I fix the internet issue?

The Switch supports both 2.4 GHz and 5 GHz Wi-Fi, but sometimes the console refuses to connect or keeps losing the network.

Main causes:

Incorrect password or router settings error

Interference on the 2.4 GHz band

Outdated console firmware

Restrictions from the internet provider (NAT, blocks)

What you can try:

Restart the router and the Switch itself

Forget the network in the console settings and reconnect

Try connecting to another access point (for example, mobile hotspot)

Change the Wi-Fi channel in the router settings (especially for 2.4 GHz)

Update the Switch firmware to the latest version

For NAT errors — enable UPnP on the router or manually open the ports for the Switch
