The alert "Uplink lower than 100M" in Nebula indicates that the speed of the connection between your access point And the switch is lower than the expected 1 Gbps . Instead, it might be operating at 10/100 Mbps. Here are the common causes and solutions to resolve the issue:

• Check Ethernet cable quality: Ensure the AP is connected using a high-quality Ethernet cable rated Cat6 or higher, which supports 1000 Mbps/full-duplex speeds.
• Verify switch port capability: Confirm that the port on your switch supports at least 1 Gbps.
• Review port settings: Check that the port’s speed and duplex settings are configured for auto-negotiation.
• Test with different ports and cables: Connect the AP to an alternative switch port and Ethernet cable to identify if the issue lies with a faulty port or cable.
