Interference guide
Zigbee and Wi-Fi interference basics
This page is for understanding the basics before you start re-pairing devices or moving
channels randomly. The goal is to help readers think about radio crowding, device
placement, and small changes that make the network easier to support.

Radio-path basics
Physical placement matters first
Keeping radios too close together can create avoidable problems before software settings are even involved.
One change at a time wins
Move, retest, and observe before you combine multiple changes and lose the pattern.
Interference is only one cause
Pairing failures and device drops can also come from weak routing, power issues, or bad placement.
What to review first
Keep the diagnosis narrow
- Check how close the coordinator, router, access point, and noisy USB gear sit to each other.
- Notice whether one room or one side of the house has more trouble than the rest.
- Review whether the problem is pairing, long-term reliability, or delayed response after pairing.
- Change one placement or network variable at a time so the result means something.
