On the covered Nintendo Switch console, 2110-1115, 2110-2000 through 2110-2899 means the console cannot use the wired connection: the LAN adapter is found but nothing answers over the Ethernet cable, or the cable, port or adapter is at fault First, seat both ends of the Ethernet cable firmly and confirm the dock or USB LAN adapter is the model that carries a LAN port.
Differential
Likely causes of “Nintendo Switch console code 2110-1115, 2110-2000 through 2110-2899”, and how to tell them apart
- 1
A loose, damaged or wrong Ethernet cable
What separates it The console is on a wired connection and cannot reach the network, and one end of the cable does not click in firmly
How to confirm Seat both ends firmly; then try a second cable, because Nintendo says a working second cable means the first is damaged
- 2
A dead or unresponsive port on the router
What separates it A different device on the same cable and port also gets no connection
How to confirm Move the cable to another LAN port; most routers have at least four, and Nintendo asks you to try a different one
- 3
A dock without a LAN port, or a USB LAN adapter that is not detected
What separates it No wired option appears in Internet Settings, or the adapter is found but communicates with nothing
How to confirm Confirm the dock has a built-in LAN port or add a USB LAN adapter; try another USB port on the dock
- 4
The router is not answering while the modem is fine
What separates it 2110-2091 shows and the adapter is detected but no network device responds
How to confirm If the modem and router are separate devices, connect the cable straight to the modem; success there points at the router
- 5
The console is not docked
What separates it The wired connection option is missing from the Internet Settings screen entirely
How to confirm Nintendo says the console must be docked and in TV mode to connect online by wire
Before you touch a setting
Record this first — changing settings destroys the evidence
- The exact code, and whether it is 2110-1115, 2110-2091 or a code in 2110-2000 to 2110-2899
- Which dock you have and whether it has a LAN port or uses a USB LAN adapter
- Whether a second Ethernet cable and a second router port change the result
- Whether the modem and router are separate devices, and whether the cable works when plugged into the modem
Try in this order
0 of 8 completedWhat to do first
Reversibleseat both ends of the Ethernet cable firmly and confirm the dock or USB LAN adapter is the model that carries a LAN port.
Correct only the documented fault domain
ReversibleReseat the cable at both ends, try a different cable and a different router port, restart the console, power cycle the modem and router, and set up a wireless connection as a comparison.
Seat both ends of the cable
ReversiblePush the Ethernet cable into the LAN port or adapter on the dock and into the router or modem until each clicks. Nintendo's articles for all three codes start here, because a cable that does not stay secure is the most common cause.
Swap the cable, then the router port
ReversibleUse a second Ethernet cable; if it works the first was damaged. Then move the cable to another LAN port on the router, since most routers have at least four ports and one may be faulty.
Check the adapter and the dock
ReversibleA USB LAN adapter goes in a USB port on the dock; try a different one. A dock without a built-in LAN port needs the adapter, and a Switch Lite uses a licensed accessory such as HORI's Dual USB PlayStand instead of a dock.
Restart the console and power cycle the network
ReversibleHold POWER for three seconds and choose Power Options, Restart. Then unplug the modem and router for 30 seconds and start the modem first, waiting for steady lights before the router.
Isolate the router with a direct modem connection
ReversibleIf the modem and router are separate boxes, plug the Ethernet cable straight into the modem. If the console connects, Nintendo says the router is the likelier fault and a different router may resolve it.
Compare against a wireless connection
ReversibleSet up Wi-Fi as well, which Nintendo recommends anyway so the console connects when it is not docked. If Wi-Fi works and wired does not, the fault is in the cable, dock, adapter or port.
Every code on this page
What Nintendo's article says about each code
Nintendo publishes a separate article for every code below, and the fix on this page is the fix all of them share. The line beside each code is what that code's own article adds: the message, the situation, or the one step that differs.
- 2110-1115
- Cannot connect by wire or wireless; Nintendo checks both ends of the Ethernet cable first, then a different cable and a different router port, then restarting the console and power cycling the network.
- 2110-2000 through 2110-2899
- A general range from 2110-2000 to 2110-2899 for trouble connecting; for a wired connection it asks for a secure cable, a different cable and a different router port, and for a wireless one it starts with the password.
Stop boundary
When this stops being a self-service repair
- !If a second cable, a second router port and a direct modem connection all fail, Nintendo says the console may need service and asks you to contact them
- !Do not force an Ethernet plug or an adapter into a port that does not fit; a bent pin in the dock is a repair, not a setting
- !Router firmware updates and factory resets belong to the router's maker, so contact them before attempting either

Sources behind this answer
Where the manufacturer's article stops. These articles cover the wired path: an Ethernet cable from a dock or USB LAN adapter to the router. 2110-2000 to 2110-2899 is a general range that also has a wireless branch, which this page summarizes but does not repeat in full; the wireless password and address problems have their own pages.
Exact questions
Common questions
What does 2110-1115, 2110-2000 through 2110-2899 mean on a Nintendo Switch console?+
the console cannot use the wired connection: the LAN adapter is found but nothing answers over the Ethernet cable, or the cable, port or adapter is at fault
Why does my Switch show a wired option that does not connect?+
The adapter is being found but nothing answers over the cable. Reseat the cable at both ends, swap it and try a different port on the router.
Can I use Ethernet with the Switch undocked?+
No. Nintendo says the console has to be docked and used in TV mode to connect online by wire, which is why it also recommends setting up Wi-Fi.
Does every dock have an Ethernet port?+
No. A dock without a LAN port needs a USB LAN adapter to make a wired connection, according to Nintendo's articles, and a Switch Lite needs a licensed accessory with a USB port.
How do I tell whether the router or the cable is at fault?+
Swap the cable first, then the router port, then plug straight into the modem if it is a separate box. The step at which it starts working tells you which part failed.
Do I need a different router?+
Only if a direct connection to the modem works and the router does not, which is the situation where Nintendo says a different router may resolve the connection issue.
