Advanced Settings
button on the
Settings tab.
•
2.4GHz Preamble
. An Auto setting might give slightly better performance. A Long setting
might provide a more reliable connection or slightly longer range.
•
Transmit Power
. Lowering the output power level lets you reduce the chance of interference
with other nearby access points but reduces the range of your adapter.
•
Wireless Mode
. Depending on your wireless adapter, you can choose some of the available
802.11 wireless protocols.
•
Fragmentation Threshold
. This is the maximum packet size used for fragmentation. Packets
larger than the size programmed in this field will be fragmented. The Fragment Threshold
value must be larger than the RTS Threshold value.
•
RTS/CTS Threshold
. The packet size that is used to determine whether it should use the
CSMA/CD (Carrier Sense Multiple Access with Collision Detection) mechanism or the
CSMA/CA (Carrier Sense Multiple Access with Collision Avoidance) mechanism for packet
transmission. CSMA/CD is slightly more efficient.
Note:
For Windows Vista computers, you must have administrator rights to access the
