●
Fragmentation Length Threshold [Bytes]
Specify the maximum packet size transferred on the wireless link. Large packets are
divided up into small packets prior to transmission and then reassembled into the original
size after they have been received. This can be beneficial if the transmission quality is
poor because larger packets are more difficult to transmit. However fragmentation into
smaller packets means a poorer throughput.
●
HW Retries
Specify the number of hardware retries. The hardware repetition is performed by the
WLAN chip itself when it tries to repeat an unacknowledged packet immediately.
If all hardware repetitions were unsuccessful, the packet is deleted.
●
Force roaming on link down (Only in access point mode)
If the wired Ethernet interface is no longer available (cable break, connector removed), a
client connected over the wireless network is not aware of this. The access point can
force the logged-on clients to roam by deactivating its WLAN interface. The client then
attempts to log on at a different access point. You enable this feature by selecting the
"Force Roaming on link down" check box.
