8. Open the folder. A list of available .img files should appear.
9. Click on the desired .img file. The file name should then appear in the Name box.
10. Click on OK and the image should be loaded into the adapter’s flash memory.
11. If the load is successful, a “Firmware Upgrade Complete!” message will appear.
An alternate, easier method, if you have the right hardware, is:
1. After downloading and extracting the .img file, load the .img file onto a USB Zip drive.
2. Connect the Zip drive to the tablet. It will show up as Hard Disk in My Computer.
3. Execute steps 5-11 above.

Status
This tab displays several useful pieces of information.
• Cisco 350 is Associated to. This is the MAC address of the associated access point.
• Cisco 350 is Associated to. This is the MAC address of the associated access point.
• Signal Strength. This is the signal strength for all received packets. The higher the value and the
more green the bar graph is, the stronger the signal. The histogram below the bar graph provides a
visual interpretation of the current signal strength. Differences in signal strength are indicated by
the following colors: green (strongest), yellow (middle of the range), and red (weakest).

the following colors: green (strongest), yellow (middle of the range), and red (weakest).
• Signal Quality. This is the signal quality for all received packets. The higher the value and the
more green the bar graph is, the clearer the signal. The histogram below the bar graph provides a
visual interpretation of the current signal quality. Differences in signal quality are indicated by the
following colors: green (highest quality), yellow (average), and red (lowest quality).

• Overall Link Quality. This is the client adapter's ability to communicate with the access point,
which is determined by the combined result of the adapter's signal strength and signal quality. The
range of values is: Not Associated, Poor, Fair, Good, and Excellent.

• Driver Version. This is the version of the Cisco adapter card driver that is loaded in the
YEStablet.
• Firmware Version. This is the version of the firmware that is loaded in the Cisco adapter card.
• Message Integrity Check. MIC prevents attacks on encrypted packets called bit-flip attacks.
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. The MIC, when
implemented on both the access point and all associated client devices, adds a few bytes to each
packet to make the packets tamper-proof. There is no configuration parameter for MIC in ACU; it
is automatically implemented in the Aironet 350 adapter if WEP is enabled and the access point is
configured for MIC.

Current IP address: This is the YEStablet IP address that has been dynamically assigned by a
DHCP server or that has been statically assigned in Control Panel Æ Network and Dial-up
Connections.

Statistics
This tab enables you to view statistics that indicate how data is being received and transmitted by the
client adapter. It also shows message integrity check (MIC) statistics if MIC is enabled on the access
point. The receive and transmit statistics are host statistics. That is, they show packets and errors
received or sent by the adapter. Link status tests from the access point are performed at the adapter
firmware level; therefore, they have no effect on the statistics shown here.
Receive statistics are defined in Table 2. Transmit statistics are defined in Table 3. MIC statistics are
defined in Table 4.
