SOLVED UM3 not connecting over LAN

[MaxMax 0]

I unpacked and installed my UM3 yesterday.

The printer was found (LAN) and I authorized the connection and transferred the configuration. Then the connection was lost and have never been restored again.  

In Cura 3.0.4, UM3 shows up in the list over network devices (discovery works). However, when I click "connect", nothing happens. No message nor error message, just absolutely nothing.  

UM3 is configured for LAN (checkbox ticked), it got an IP address from my DHCP server and it has connection with the world because it downloaded and upgraded the firmware.  

I have tried to reboot both UM3 and Windows several times with the same result.

In Win8 Firewall Cura is set as an application on private networks (and I'm on a private network).  

I also tried to setup the WiFi, but there is no way to select encryption so I have no idea if UM3 can connect to my router using WPA2. After setup it fails to get an IP address and I'm 100% sure the password is right.

So far I have not been able to connect either by LAN or WiFi.

I found the list of used ports but it is incomplete. The corresponding protocol and in/out bound info is missing. Here is my assumption:  

 

5353 UDP Inbound    8080 TCP/IP Outbound    80   TCP/IP Outbound

 

 

I also find it strange that I can't set a static IP, Submask or Proxy information.

Automatic functionality is only good when it works, but as soon there is a problem or incompatibility, it is the worst basically telling "You are to stupid to handle this" when in fact it is the automation that is stupid. There should always be an "advance" mode to manually set up things.  

This time I really hope it is me that is stupid and it's a misunderstanding of how this is supposed to work.

Please help me to understand.  

 

 

Update (quite annoyed):  

This start's to be really annoying now when I can't even post this to get help with a brand new product:  

"Your computer or network may be sending automated queries. To protect our users, we can't process your request right now. For more details visit"  

This isn't really a good start for the relation with Ultimaker.

Well you have so many ways to move on I'm not sure where to start. Lets start with the fact that it was able to update so I would think that means it has access to the internet. If from the panel you change it to developer mode and go back to the main screen it will show an ip address at the top. If it can't connect it uses some weird ip address - I think 192.264... which is the kind of failure address.

If you have a phone or ipad or laptop you can put the printer into wifi config mode. There are instructions somewhere but basically the printer will be a hot spot. Then you go to your phone/laptop/ipad and look at wifi access points and one will say something about ultimaker. Connect to that, open a browser and you can configure your printer to tell it which network to use, and what the password is for your wifi.

Thirdly you can use ethernet cables and just connect directly to your network. I have ethernet wired all over my house so I use that for one of my UM3's and wifi for the other.

And finally once you get all this working I recommend you go to your router and set it up so your um3 gets a static ip adress. Meaning the address will never change from here on out. I found that to be a better experience especially since I ssh into my printer a lot.

Thanks for the reply. I read somewhere else to delete the printer in Cura and select a new one. I did this and after fiddling with the WiFi setup it finally connected after the third setup round. I don't dare to touch the network now to try the LAN cable again.

Yes, I have already set a static IP in the router and the faulty IP address you are looking for start with 169.254.xxx.xxx

Now I'm having other problems with material setup over network... I will post a new one for that.

// Thanks.
