No Hard Limit 

There is no hard limit to the number of WiiM devices you can use. The maximum capacity primarily depends on the performance and bandwidth of your home network. 

Wi-Fi Capacity and Interference

Keep in mind that as you add more devices via Wi-Fi, the potential for wireless interference and network congestion increases. Factors such as router performance, signal coverage, and the number of active wireless clients will all impact system stability. 

Use Ethernet for Maximum Stability

To minimize interference and ensure a robust connection, we recommend using Ethernet whenever possible. All WiiM models except the WiiM Mini feature a built-in Ethernet port. A wired connection is highly recommended for multi-room setups involving several devices.
