• use a USB cable extension (possibly USB 2.0 as the 3.0 signals could create additional noise)
• change the Zigbee channel (Phoscon app → Gateway → Advanced)
  • please note that Zigbee channels and WiFi channels are the same, therefore use a WiFi scanner to find a channel that is as free as possible
• keep away from other 2.4gHz devices (e.g.: access points, keyboard/mouse receivers, bluetooth, cordless phones, microwaves, etc.)
