2+ Connect Wifi and LAN connection problem


Recommended Posts

Posted · 2+ Connect Wifi and LAN connection problem

Hi everyone,


We have purchased a UM2+ connect for our school. We have tried to install both via wi-fi and via LAN but the printer does not connect either way.


Wi-fi: we have connected through a smart phone and had a success message on the phone, the printer however says connection failed.

LAN: we are given an IP address but then cannot connect through Digital factory. With the error message to plug in an ethernet cable.


We have gone through all the steps suggested on the Ultimaker support. Any help would be greatly appreciated.

    Unfortunately very few people on here have a UM2+C.  It seems it's not popular although the few people I know who have it think its the best print Ultimaker makes for the price.  Anyway the only person I know who might have one is this guy and he knows networks:  @Smithy


    Although he may have questions.  What do you mean "same problem here".  I guess if you have trouble with wifi, wired is so much simpler so did you do a wired connection?  What do you mean by "given an ip address"?  Are you not using DHCP to distribute IP addresses?

    I would also recommend to start with a ethernet connection first, just to see if that works.


    There could be two main reasons why it fails:

    - The printer don't get an IP address from your DHCP server or router

    - The printer communication is maybe blocked by a firewall (often the case in schools)


    The UM2+C can only operate when he can reach the internet, there is no local-only communication over LAN as it is with other UM printers and you can only send print jobs via the cloud (digital factory)


    It would also be helpful when you can give some more information about your environment. Do you have a bigger network infrastructure or just a simple router? Are there any firewalls or other security things installed? 


    In bigger companies, an (unused) ethernet port is often blocked or disabled - or has no access to the internet.
