• Same Group ID• Define Priority, Primary has highest Priority (30 is highest)
- If same priority, compare the LAN IP (192.168.1.1>192.168.1.2)
Routers Setup

V2925_A V2925_B
• Same group should share same Authentication Key• Choose Management Interface for communication• Allow updating DDNS when CPE become Primary
- All members share the same DDNS profiles
Routers Setup
17
V2925_A V2925_B
• Choose LAN subnets for HA• Define the Virtual IP
- All members should have the same Virtual IP
Routers Setup
19
V2925_B
• Use different LAN IP• LAN IP will be replaced by HA Virtual IP
- Only see this message when HA is enabled and Virtual IP is set

Summary of AirTime Fairness
76
• Improve Overall WiFi Performance, in Most Cases - Stations with Good Link Rate get Increased - Stations with Poor Link Rate get Decreased
• Hint: In Central AP Management >> Load Balance, set Force Overload Disassociation as by single Strength
