Fault Description

Wireless clients are disconnected abnormally and have no Internet connectivity.

Device Model and Firmware

Device Type	Device Model	Firmware Version
Wireless controller	WS6008	AC_RGOS 11.9(6)W3B1, Release(11160200)

Access point	AP850-AR(V3)	AP_RGOS 11.9(6)W2B7, Release(10170604)

Cause Analysis

1. Check for signal interference among APs and their placement in the environment. It is found that the APs are placed too close to each other, resulting in high channel utilization.
2. Check the client association logs on both the AP and the AC for wireless clients experiencing issues. The logs reveal abnormal IP address acquisition problems for these clients.

Enable DHCP snooping on the AC and check DHCP information for the wireless clients.The DHCP process appears normal.

Upon further inspection of client logs on the AP, numerous "handshake failed" entries were found, indicating an issue with the firmware version.

Root Cause

1. For AP deployment, adjust the radio transmit power of APs and adjust the AP channels based on the AP placement map.
2. Upgrade the AP firmware to the latest version W3B1.
Solution

1. Lower the radio transmit power of APs andadjust AP channels based on the AP placement map.
