WiFi Not Connecting
Anycubic 3D Printer (FDM)
Severity:What Does This Error Mean?
Anycubic Kobra WiFi only works on 2.4 GHz networks. If your router broadcasts both 2.4 and 5 GHz under the same name, the printer may be trying to connect to 5 GHz. Separate the bands or use a 2.4 GHz-only network.
Affected Models
- Anycubic Kobra 2 Pro
- Anycubic Kobra 2 Max
- Anycubic Kobra S1
Common Causes
- Printer connecting to 5 GHz Wi-Fi — only 2.4 GHz is supported
- Wrong Wi-Fi password entered on the touchscreen
- Router security set to WPA3 — some models need WPA2
- Printer too far from the router
- Anycubic app not yet paired after Wi-Fi connection
How to Fix It
-
Make sure you are connecting to the 2.4 GHz band.
The Kobra 2 Pro and Max do not support 5 GHz Wi-Fi. If your router has combined bands (e.g., 'MyNetwork' for both), log into your router and split them into separate SSIDs.
-
Re-enter the Wi-Fi password on the printer touchscreen.
Go to Settings → Network on the touchscreen. Delete the saved network and re-enter your password carefully — the touchscreen keyboard can be slow.
-
Check your router's security type — use WPA2 if possible.
Some Kobra models have trouble with WPA3. Log into your router admin panel and try setting security to WPA2/WPA3 mixed or WPA2-only.
-
Move the printer closer to the router or use a Wi-Fi extender.
Concrete walls and distance weaken 2.4 GHz signal. A temporary fix: move the router closer while setting up, then return it after pairing.
-
Pair the Anycubic app after successful Wi-Fi connection.
Wi-Fi connection on the printer and app pairing are two separate steps. Once connected to the network, open the Anycubic app, tap Add Device, and follow the pairing flow.
Frequently Asked Questions
Can I use the Anycubic Kobra without Wi-Fi?
Yes. Wi-Fi is optional. You can print from a USB drive or SD card without any network connection. Wi-Fi is only needed for the Anycubic app remote monitoring.
Does the Anycubic app work from outside my home network?
Yes — once paired, the Anycubic app works over the internet. You can monitor prints and get notifications from anywhere on your phone.
