Ultimaker 3 cannot connect to WiFi

Recommended Posts

Posted · Ultimaker 3 cannot connect to WiFi

Hey guys!

I am quite new to the Ultimaker and the community. A few years ago I had a different (selfbuilt) 3D printer, but things got very frustrating, so I paused until I bought myself an Ultimaker 3, two days ago. Yesterday I did the whole setup and everything went well and worked perfectly fine. In the evening I did a Firmware Update and shut the printer down afterwards.

After shutting everything down for the night, I tried to print today and noticed, that the printer was not showing in Cura anymore. So I checked the network settings on the printer and noticed that the printer was not connected to WiFi anymore. Alright, so I did the whole procedure of connectign the printer again, but it always failed. After I enter the WiFi Password (on several devices by now), the printer states that it tries to connect to the network. This message is shown for a fair amount of time, until I get the message, that the connection failed. I also tried to restart my WLAN router and the printer. In the end I also reset the printer to factory settings as it was suggested in several threads, but nothing helped yet. I did not change anything else about my local network, so this leaves me pretty help- and clueless on what to do next ūüėě

Does anybody maybe know this issue and can help me?

Best wishes
Steve

Had a similar Issue.

After the last Firmware Upgrade i can't connect the Printer (UM3) to WiFi. The Printer try to setup the Access Point for WiFi config, but no WiFi visible. I try a Factory Reset, does not help.

Before the Firmware Update the Connection was fine.

 

Thanks for help,
Tom

what do you mean with add manually? Add the Printer IP to an existing WiFi?

 

My Problem is the invisible (not existing?) Printer AP in the WiFi Setup...

So I tried to connect the printer over Ethernet now and it work great ... until ... I switched the printer off and on again. Now this connection also fails on me, beacuse the printer ist not showing in the printers to add anymore.
So this leaves me with the hassle of printing via USB Stick ...

Is there maybe help out there?

Has anyone figured out a solution to this WiFi issue? I just purchased an Ultimaker 3 and day one am running into the same problem. I did the upgrade and it disconnects every other second from the network. The support folks at Ultimaker claim I need to replace the WiFi card manually to solve this, but they didn't indicate whether it's an issue with specific units or that all units are incompatible with the upgrade. Thoughts?

I just setup a UM3 Extended. Upgraded the firmware via USB. And I am unable to complete wifi setup. It creates an access point I cannot connect to. I've tried using an iPhone, 2 Android phones, and a Macbook Pro and they all fail to connect to the access point my Ultimaker created. Is there a fix yet?

I enabled developer mode and ssh'd to the Ultimaker 3 Extended. I saw the following in dmesg; is the serial suspect? I am not expecting a serial of 12345.

 

[    6.259099] usb 1-1: New USB device found, idVendor=0cf3, idProduct=9271
[    6.265879] usb 1-1: New USB device strings: Mfr=16, Product=32, SerialNumber=48
[    6.273446] usb 1-1: Product: WLAN
[    6.276982] usb 1-1: Manufacturer: MVQ1611
[    6.281162] usb 1-1: SerialNumber: 12345
