Known bugs and issues

MLO instability with legacy clients

The Archer BE550 may experience connectivity issues with older Wi-Fi 5 devices when MLO (Multi-Link Operation) is enabled. Solution: Disable MLO in the router firmware settings. This will reduce theoretical peak speed but improve compatibility with legacy devices.

Bufferbloat and gaming lag

Solution: Enable Smart Queue Management (SQM):

1. Navigate to router QoS settings
2. Enable CAKE or fq_codel algorithm
3. Set your upload bandwidth to 90% of your actual plan speed
4. This eliminates bufferbloat, reducing ping spikes by 20–50ms

6 GHz range limitations

Solution: 6 GHz (Wi-Fi 6E/7) has limited wall penetration. Add additional mesh nodes or use a wired backhaul to extend 6 GHz coverage to distant rooms.

Step-by-step fix procedures

Fix bufferbloat

1. Connect to router via Ethernet
2. Navigate to QoS settings
3. Enable SQM (Smart Queue Management)
4. Select CAKE or fq_codel algorithm
5. Set upload bandwidth to 90% of your plan speed
6. Save and apply — wait 30 seconds
7. Test at waveform.com/bufferbloat

Fix gaming lag

1. Enable device-based QoS
2. Set your gaming PC/console to highest priority
3. Enable WMM (Wi-Fi Multimedia) for 5 GHz
4. Disable WMM power save mode
5. Set router to channel 36–48 (5 GHz) for lowest latency

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
