Common Client Side Issues with Wireless Roaming include:
1. Roaming aggressiveness of the wireless client is too high. Wireless client hops between multiple AP`s, even though signal strength is stable.
2. Roaming aggressiveness of the wireless client is too low. - Wireless client is “sticky” to a particular AP, even though stronger AP is available. Best Wi-Fi practices:
- Control the transmit power of each Access Point. - Properly set the transmit power in reference to its location, physical obstructions or type of environment and wireless interference from neighbouring AP`s. -We recommend users to set the transmit power initially to 14dBm on the 2.4GHz, and 20dBm on the 5GHz, then have an incremental of 3dBm if necessary. Use an RSSI Tool to help identify the transmit power the AP needs.
- Set a relative Fast Handover/ RSSI Threshold value. -Some wireless client devices retain connection to a weak signal, even if there`s a stronger one available. -Set the RSSI Threshold/ Fast Handover value to -80dBm, which will force the client device to disconnect from the AP and allow it to scan and connect to a stronger signal.
