The Windows XP Service Pack 1 changes the numbering of the WEP
(Wireless Encryption Protocol) key index from the numbering assigned to
the key in the original release of Windows XP. In the original (XP Gold)
release, the index keys are numbered 0 through 3. Windows XP Service
Pack 1 (SP1) changes the numbering of the index keys to 1 through 4.

Rate indication in the Connection Status
fluctuates
If the rate indication in the Connection Status fluctuates even though the
unit is stationary, no action may be necessary.
The algorithm for data rate determination checks the data packet by
packet and adjusts the data rate for current conditions. Lost or corrupted
packets will cause the data rate to fall back, and subsequent good packets
will cause the rate to increase.
Packets can be lost or corrupted by over-the-air disturbances. For
example, in an office environment, other transmissions from other
WLANs may cause disturbances. In a home environment, disturbances
may be caused by microwave ovens or cordless telephones.
Some WLAN cards do not update their rate indications and may not
display the actual connection rate.
