Hello @DannyBosman ,

Welcome to our community.

This appears to be a device-specific compatibility with your HEOS speakers through the powerline extender's WiFi. Here are some troubleshooting steps that may help resolve this:
 

1. Check router settings that might block specific devices:
• Ensure your router doesn't have settings like MAC Filtering or Access Control enabled, as these can block certain devices from connecting properly through the powerline network
• Check if there are any device limits or restrictions on your router that might affect the HEOS speakers

2. Modify the WiFi settings on the powerline extender:
• Try changing the WiFi name (SSID) and password on your WPA7617, avoiding special characters like apostrophes
• Consider changing the wireless mode settings. For guidance: How to customize wireless settings

3. Reset and reconfigure the powerline devices:
• Reset the WPA7617 powerline extender by pressing and holding the Reset button for at least 5 seconds
• Re-pair the powerline devices following this guide: How to secure (pair) the Powerline Network
• After reset, try connecting your HEOS speakers again with the default settings

4. Update firmware:
• Ensure your WPA7617 is running the latest firmware, as updates often fix compatibility issues with specific devices
• After upgrading, re-pair the powerline devices. Upgrade guidance: How to upgrade firmware

5. Test with different powerline WiFi settings:
• If your WPA7617 has cloned the WiFi settings from your main router (same SSID/password), try giving it a unique WiFi name instead
• Some devices can have issues when multiple access points share the same network name
