Nintendo Switch Error Code 2110 | Internet Connection Error Fix

Error code 2110 on the Nintendo Switch is always a Network / Internet Connection error. It means your Switch is struggling to talk to your Wi-Fi router.

The specific fix depends on the last 4 digits of the code (e.g., 2110-3127 vs. 2110-1100), but here is the master fix list that covers 90% of these errors.

1. The “DNS” Fix (For 2110-3127)

If your error ends in 3127, your Switch is connecting to Wi-Fi but getting “lost” on the way to the internet.

1. Go to System Settings > Internet > Internet Settings.

2. Select your Wi-Fi network and click Change Settings.

3. Scroll down to DNS Settings and change it from Automatic to Manual.

4. Enter these Google DNS numbers:

   • Primary DNS: 008.008.008.008

   • Secondary DNS: 008.008.004.004

5. Save and try connecting again.

2. The “Hardware” Fix (For 2110-1100 or 1118)

If your error ends in 1100 or 1118, your Switch likely cannot find any Wi-Fi networks at all. This is often a software glitch or a loose internal antenna.

• Hard Restart (Critical): Do not just put it to sleep. Hold the Power Button down for 3 full seconds > Select Power Options > Restart.

• Test Distance: Stand right next to your router. If it connects there but nowhere else, your Switch’s internal antenna might be failing.

3. The “Interference” Fix (For 2110-2003)

If your error ends in 2003, something is physically blocking the signal.

• Check Obstacles: Are you using the Switch behind a TV, near an aquarium, or next to a microwave? These block Wi-Fi signals.

• 5GHz vs 2.4GHz: If you have a dual-band router, try connecting to the 2.4GHz band (usually labeled “MyWifi_2G”). It is slower but punches through walls better than 5GHz.

If none of these work:

You can bypass the Wi-Fi entirely by buying a USB LAN Adapter (about $10-15) and plugging an ethernet cable directly into the Switch dock. This works even if your internal Wi-Fi chip is broken.
