Pro DJ Link keeps crashing after adding DJM-900 NXS2

Until now I experienced a very stable Pro DJ Link network with my Windows Notebook, my 2 CDJ-2000 NXS's, and a network router (stand alone network). I even managed to have the notebook connected to the router by WiFi and keep it stable. I did a lot of gigs with this configuration (wired or WiFi) without any issues. I didn't have a mixer connected to the network until now.

Now that i've added my brand new DJM-900 NXS2 I'm experiencing sudden network issues, which make my CDJ's disconnect and go into Emergency Loop mode after a few minutes. The DJM is running on the latest firmware (1.10).

I know that there have been issues with the DJM-900 NXS2 and Pro DJ Link, but it should have been solved in the latest firmware update.

Is there still something to be solved in a future update, or should I change the router for a simple hub, now there is more network traffic?

I bought the NXS2 for improvement, but this is a big step back
