Transmit Rate
The 802.11b wireless Ethernet standard was engineered to operate at
different data rates depending on the environment in which it is operating.
The maximum data rate is 11Mbps (11 megabits per second or 11 million
bits per second). Under the best of circumstances, the data will be
transferred at the highest rate. When excessive noise or other similar
radio signals enter the air, or the wireless device is far enough away from
the access point so the signal is weak, the wireless data can be corrupted
with data errors. Data errors result in a very slow connection because the
data has to be resent over and over until there are no errors. To combat
this, the data rate will automatically be rolled back to a slower rate to
eliminate errors by giving the signal more time to reach its intended
destination. The result is the fastest transmission possible. There are
four possible data rates: 11, 5.5, 2, and 1 Mbps.
Note: We recommend that you leave the Transmit Rate at “Fully
Automatic” and let the wireless Card do the job of transmitting
the data at the fastest possible rate. If you set the Transmit
Rate at a fixed setting, this will force data to be sent at that
rate, but errors may occur causing the data to be resent. This
could actually make the connection SLOWER.
To change the Transmit Rate:
1.
Click the down-facing arrowhead next to “Transmit Rate” and select the
desired rate.
2.
Click “Apply” to save the change.
