![]() ![]() UniFi Network supports the following channel widths: Unlike Nightly Channel Optimization, this scan may interrupt client connectivity while in progress. You can perform an RF Scan in the UniFi Network Application to identify channels with the lowest interference.If you have three APs, you can set one each to Channel 1, 6, and 11 on the 2.4 GHz band. Nearby APs should use different channels.These will optimize connectivity since they are the only non-overlapping channels. ![]() If you must use 2.4 GHz, you should only ever use Channel 1, 6, or 11.If you prefer to manually assign channels, here are a couple of rules to keep in mind: This is why having high-density deployments may contribute to speed or connectivity issues. ![]() This is true for all devices in a given area, even if they are not connected to your network (e.g., your neighbor has a lot of IoT devices). Wireless clients use a shared airspace for communication. Your network will continue to work during nightly scans. We recommend enabling Nightly Channel Optimization to ensure you are on the least-crowded, non-overlapping channels. Select Non-Overlapping and Low-Interference Channels Having a period that is too high may result in the device disconnections. The DTIM Period is a WiFi SSID setting that tells clients when to “wake”. If you have changed this value and noticed issues specific to legacy clients, we recommend setting it back to 1 Mbps. This is because some clients, particularly legacy devices (802.11b), require a low data rate in order to connect. The default minimum data rate for the 2.4 GHz channel is set at 1 Mbps to maximize compatibility. Reduce the Minimum Data Rate to Improve Legacy Device Compatibility This adds an additional layer of complexity in order to verify clear communication between clients and their server, as well as whether or not the server is properly configured. Enterprise modes use RADIUS servers to authenticate clients. WPA3 requires PMF which, as mentioned, may create client connectivity issues.įurthermore, we recommend testing with a non-enterprise security mode. Many devices, especially legacy ones, are incompatible with PMF and experience resulting connectivity issues. We recommend disabling PMF to maximize compatibility. If you still experience issues, please note that connectivity can be affected by your settings, client specifications, and any interference related to utilization or RF environment congestion.ĭisable Protected Management Frames (PMF) for Improved Compatibility Our default settings are specifically configured to optimize compatibility with the largest number of clients.
