To help you keep an eye on this gap refer to the signal-to-noise ratio (SNR) value. When the gap gets very small, the signal could be drowned out by the noise. The smaller the gap, the worse the Wi-Fi performance. You want the biggest gap between the signal and noise levels as possible. The noise levels can vary, but typically range between -90 dBm (typical moderate noise) to -98 dBm (nearly no noise). The signals have to combat noise or interference from other Wi-Fi devices, other wireless devices in the same frequency band, or even other non-wireless electronics interfering, like microwave ovens or electrical boxes. Signal levels typically range from -30 dBm (best signal possible) to -90 dBm (least signal possible). Such signals from other devices are just noise to yours. A client can be right next to an AP with excellent signal but be unable to keep a connection if the signal from another Wi-Fi or any other type of radio-frequency device is too great. Optimize the signal-to-noise ratioĪlthough some people only talk about signal levels when designing or troubleshooting Wi-Fi networks, you must consider more. So, try to find the root causes of any symptoms and be very intentional about the changes you make. If so, maybe you blindly add more access points (AP) and, not knowing that you already had interference, that can actually cause more interference. The symptoms of interference issues can easily be mistaken for symptoms of other, more apparent problems such as poor Wi-Fi coverage.

There can be interference from your own network or neighbor's, non-Wi-Fi wireless devices, microwaves, and even radar systems. Since Wi-Fi transmits over the airwaves, it’s of course much more susceptible to interference than the wired network.
