balancing and fault tolerance but requires a
switch that supports IEEE 802.3ad with LACP
mode properly configured.
Balance-tlb
(Adaptive
Transmit Load
Balancing)
Balance-tlb uses channel bonding that does not
require any special switch. The outgoing traffic is
distributed according to the current load on each
Ethernet interface (computed relative to the
speed.) Incoming traffic is received by the current
Ethernet interface. If the receiving Ethernet
interface fails, the other slave takes over the MAC
address of the failed receiving slave. Balance-tlb
mode provides load balancing and fault tolerance.

Balance-alb
(Adaptive
Load
Balancing)
Balance-alb is similar to balance-tlb but also
attempts to redistribute incoming (receive load
balancing) for IPV4 traffic. This setup does not
require any special switch support or
configuration. The receive load balancing is
achieved by ARP negotiation sent by the local
system on their way out and overwrites the
source hardware address with the unique
hardware address of one of the Ethernet
interfaces in the bond such that different peers
use different hardware address for the server.
This mode provides load balancing and fault
tolerance.

Wi-Fi
To connect to a Wi-Fi network, plug a USB wireless dongle into the NAS. The NAS will detect
a list of wireless access points. You can connect the NAS to a Wi-Fi network in two ways.
Note:
 Wireless connection performance depends on many factors such as the adapter model,
the USB adapter's performance, and the network environment. Wired connections will
always provide greater stability and performance.
 The system only supports one USB Wi-Fi dongle at a time.
