Wi-Fi disconnections or intermittent connectivity can significantly impact productivity and lead to frustration. This article aims to guide you how to resolve these issues, particularly focusing on standalone APs, to ensure a stable and reliable wireless network connection.

Update Client Drivers

Issue: Outdated drivers on client devices can lead to poor connectivity.

Solution: Check if a new driver is available for the client device and install the latest version. This ensures compatibility and optimal performance with the wireless network.

Optimize AP Deployment

Issue: Poor AP placement can result in weak signal strength.

Solution: Fine-tune the deployment of the Access Points (APs). Ensure that the client connects to a signal of –70dBm or above for better connectivity.

Wireless Environment Fine-Tuning

Issue: The AP handles a high number of connections.

Solution: Wireless Environment Fine-Tuning

Going to Configuration > Wireless > AP management > Radio 1 Setting and Radio 2 Setting and do the corresponsive configuration.

Maximum output power

Adjust your 2.4GHz radio power to lower than your 5GHz radio at least 5dBm. It helps the client is easy to connect to 5GHz that less interference, and up to 25 channels are available and non-overlapped.

Channel width: Reduce 5GHz to 40MHz, and then 20MHz, narrow channel width to minimize co-channel interference on each radio.

Enable DCS Client Aware, disable this feature to let the AP jump to the better channel when the DCS work and there are still clients connect to AP.

Avoid 5G DFS channel, disable this feature to let the AP have more options to prevent channel interference.

WLAN rate control

Increase your WLAN rate control for 2.4GHz to 5.5Mbps, while 5Ghz to 12Mbps. The higher rate is set, the shorter transmission period can be achieved because less airtime will be occupied by management frames.

Going to Configuration> Network > Storm control

Broadcast Storm Control and Multicast Storm Control, enable these features on both the AP and switch port (if supported) that the AP is connected to. Storm Control is to limit the broadcast or multicast packets amount per second (pps). Enable the storm control on access point will drop ingress packets on uplink port to release more airtime to transmit data.
