UM3 WiFi Connection Failure

[flyntm 2]

I am having trouble connecting my UM3 to my WiFi.  I go to Systems>Network>Run WiFi Setup and it creates a WiFi Network.  I connect to the created network on my phone or computer and click "Start WiFi Setup". I name the printer "UM3-5" ,  then select the my local WiFi network and enter the WiFi password. The UM3 reports "Connected". WiFi is selected on the Network Menu.

Now I go to Cura and try to Add the Printer. Today it can't seem to find the UM3 when I click refresh.  Other days it works?  Even when it's working, it seems that when I leave it off for a few days I must go through this hit or miss process of resetting up WiFi.

What am I doing wrong?

I have the same issue for years. The Wi-Fi connection is just lost sometimes. The Wi-Fi module of UM3 seems very unstable. I don't know it is a firmware or hardware issue. But it is really troublesome to me, I can't use network to send print or check the printing status.

 

A long time ago, I sent the UM3 to Ultimaker reseller to fix the issue. They said Ultimaker will fix this issue in future firmware release. But it is still not fixed yet.

With the new 5.2.17 firmware for the Ultimaker 3 there are some fixes for WiFi.
