Known bugs and issues

Device dropouts and band steering issues

Solution: Disable "smart connect" / "band steering" and create separate SSIDs for 2.4 GHz and 5 GHz. This gives you explicit control over which band each device connects to.

Slow device roaming between nodes

Solution: Adjust the RSSI roaming threshold in your mesh system settings. Set to -70 dBm (stronger signal requirement) for faster roaming, or -80 dBm for wider coverage.

Backhaul bottleneck

Solution: Always use wired Ethernet backhaul between mesh nodes when possible. Wireless backhaul halves throughput on every hop. If wired backhaul is impossible, ensure nodes are within 10 feet and on the same channel.

Step-by-step fix procedures

Fix device dropouts

1. Disable "smart connect" / "band steering"
2. Create separate SSIDs for 2.4 GHz and 5 GHz
3. On each device, connect to the 5 GHz SSID explicitly
4. Move mesh nodes to central locations
5. Ensure backhaul connection is stable

Fix slow roaming

1. Navigate to mesh advanced settings
2. Find the RSSI roaming threshold
3. Set to -70 dBm (more aggressive roaming)
4. Save and apply — nodes will roam at stronger signal levels
5. Test by walking with a connected device between nodes

Optimization and tuning

Performance optimization

• Enable SQM/CAKE for zero bufferbloat
• Set optimal Wi-Fi channels (1/6/11 for 2.4 GHz, 36/48/149/161 for 5 GHz)
• Enable IPv6 for lower latency
• Use 1.1.1.1 or 8.8.8.8 for DNS
• Disable WMM power save mode

Security optimization

• Change default admin password
• Enable WPA3 or WPA2/WPA3-mixed encryption
• Disable remote management if not needed
• Enable auto-update for firmware
• Create a separate guest Wi-Fi network
