Why are some WBE660S devices connecting at only 1Gbps or 5Gbps instead of 10Gbps?

This behavior is typically related to physical layer issues such as cable quality, cable length, termination quality, or port negotiation inconsistencies.

To isolate the cause, test with certified Cat6a cables, swap APs between ports that successfully negotiate 10Gbps, and verify that both ends of the cable are properly terminated. These steps help determine whether the root cause lies in the cabling, the switch port, or the AP hardware itself.
