Setting the Autonegotiation Mode

By default, autonegotiation is set to on. This means that the adapter communicates with its link partner to determine a compatible network speed, duplex mode, and flow control capability.

▼To Disable Autonegotiation Mode

If your network equipment does not support autonegotiation, or if you want to specify your network speed, you can set autonegotiation to off on the ipge device.

Note – Disabling autonegotiation mode can cause collisions.
