Why does wireless performance degrade when two APs are used together?

If the performance decreases when two Access Points (APs) are running simultaneously, it might be caused by co-channel interference. This happens when both APs are operating on the same wireless channel, such as CH6, leading to overlapping signals.

Additionally, environmental factors play a major role. Objects like floors, cupboards, and metallic structures can significantly weaken the signal, causing lower RSSI (Received Signal Strength Indicator) values.

How can the issue be resolved?

1. Enable Dynamic Channel Selection (DCS) on your APs to automatically select less congested channels. Follow the guide here: Nebula Deployment Radio Settings Guide.
2. Check and increase the maximum output power setting slightly for better wireless coverage. Monitor for any potential co-channel interference during the change.
3. Ensure environmental factors are reduced as much as possible. Placing the APs strategically may also minimise signal obstructions.

By following these steps, you can improve the performance of the wireless environment with multiple APs.
