KNOMI2 randomly showing "Logo stripes"

[dmit2k]

Hello,

having strange issues with a new KNOMI2 device:

1. successfully set up and connected to the printer, but it randomly shows those animated stripes (Voron logo?) on the screen, both in standby and when working with menus.

First I thought than may be a connection problem, but then discovered that it has its own specific notification for WiFi connection issues

2. extremely poor WiFi stability, and attaching the supplied antenna changes absolutely nothing.

The Knomi is located a couple of meters from my WiFi point and other 2.4GHz devices are working flawlessly.

Any ideas or suggestions on either issue?
