Go to Control Panel > Network > Network Interface, then click Create > Create Bond.
Choose a mode:
- Adaptive Load Balancing: works even if the switch does not support Link Aggregation; do not enable Link Aggregation on the switch in this mode.
- IEEE 802.3ad Dynamic Link Aggregation: requires LACP / 802.3ad on the switch; if multiple switches are used, they must be stackable and properly configured.
- Balance XOR: requires Static Link Aggregation on the switch.
- Active/Standby: gives fault tolerance without switch configuration.
Select the two network interfaces, set the IP/subnet/gateway if needed, and finish. A new Bond interface will appear.
Will it improve speed? Yes, Link Aggregation can increase bandwidth and provides failover, but the traffic is automatically adjusted and balanced per connected device. It is mainly useful on models with at least two LAN ports.
