Viewing Statistics for Your Client Adapter
Step 2
Tap OK to exit the Status screen.
Viewing Statistics for Your Client Adapter
ACU enables you to view statistics that indicate how data is being received and transmitted by your client
adapter. It also shows message integrity check (MIC) statistics if your client adapter’s driver supports
MIC and MIC is enabled on the access point.
Note
The receive and transmit statistics are host statistics. That is, they show packets and errors received
or sent by the Windows CE device. Link status tests from the access point or ACU site survey tool
are performed at the firmware level; therefore, they have no effect on the statistics shown by the
Statistics screen.
Signal to Noise Ratio
The difference between the signal strength and the current noise
level. The higher the value, the better the client adapter’s ability
to communicate with the access point.
Range:
0 to 90 dB
Note
This setting appears only if you selected signal strength to
be displayed in dBm. See the
Display Units” section on page 7-2
for information.
Driver Version
The version of the client adapter driver that is installed on your
Windows CE device.
Firmware Version
The version of the firmware that is currently running on your
client adapter.
Message Integrity Check
Indicates whether your client adapter is using message integrity
check (MIC) to protect packets sent to and received from the
access point.
MIC prevents bit-flip attacks on encrypted packets. During a
bit-flip attack, an intruder intercepts an encrypted message, alters
it slightly, and retransmits it, and the receiver accepts the
retransmitted message as legitimate.
Note
MIC is supported automatically by the client adapter’s
driver, but it must be enabled on the access point.
Value:
Yes or No
Current IP Address
The IP address of the client adapter. If your Windows CE device
is set up to obtain an IP address from a DHCP server, you can
press the Renew button to initiate a release and renew of the IP
address.
Note
This parameter and the Renew button appear only on PPC
2002, HPC 2000, and CE .NET devices.
