New and Changed Information
This section describes new and changed information for Cisco Aironet client adapter firmware release 5.02.19.
Supported Client Adapters
All of the following Cisco Aironet client adapters can use firmware release 5.02.19:
•340, 350, and 4800 series PC, LM, and PCI cards
•350 series mini PCI cards
•PC-Cardbus (CB20A) cards
Firmware Is Upgraded Automatically in Windows
After you install Install Wizard file version 1.0 on a Windows computer, the firmware of any client adapter that is inserted into that computer may be automatically upgraded to version 5.02.19. Both of the client adapter's LEDs light continuously while the firmware upgrade occurs.
Caution Do not eject the client adapter while the firmware is being upgraded.
Note If you uncheck the Automatically Load New Firmware When NDIS Driver Is Updated check box on the ACU Preferences screen, the firmware will not be upgraded when future client adapters are inserted. However, this option is radio-type and, for PC-Cardbus cards, slot dependent. Therefore, if you insert a client adapter of a different card type (such as a 340 instead of a 350) or insert the same PC-Cardbus card into a different slot, the firmware will be upgraded unless you uncheck this parameter for the new card type.
Using Client Adapters with Both Windows and Windows CE Devices
If you insert a client adapter that has been upgraded to firmware version 5.02.19 into a Windows CE device, the adapter functions only if the device is running Windows CE client adapter driver and client utility version 2.30 or greater.
Upgrading to a New Firmware Release
Caution To minimize the risk of a power failure during the firmware flashing process, which could render your client adapter inoperable, Cisco recommends that your computer be plugged into AC power or have a fully charged battery at the start of flashing. If a power failure does occur, follow the instructions in the "Obtaining Technical Assistance" section to contact TAC for assistance.
This section describes how to upgrade to client adapter firmware release 5.02.19 on a computer running Windows 98, 98 SE, NT, 2000, Me, or XP. Refer to the following document for instructions on upgrading the firmware on a Windows CE device:
Cisco Aironet Wireless LAN Client Adapters Installation and Configuration Guide for Windows CE, version -03
Finding the Firmware Version
To find the firmware version that your client adapter is currently using on a computer running Windows 98, 98 SE, NT, 2000, Me, or XP, open ACU and click the Status icon. The firmware version is displayed in the Firmware Version field on the Status screen.
Upgrading the Firmware
On a Windows 98, 98 SE, NT, 2000, Me, or XP computer, you can upgrade your client adapter's firmware using either the Install Wizard or ACU. If you use the wizard, the firmware loads from the Install Wizard file and is installed along with other software components. If you use ACU, the firmware installs from an image (*.img) file that contains only firmware.
Note To ensure compatibility between software components, Cisco recommends that you use the Install Wizard to upgrade the firmware along with the other software components.
Note Firmware version 5.02.19 does not include support for rogue access point detection. If you require this feature, use ACU to upgrade to firmware version 5.02.20 after Install Wizard version 1.0 has been installed.
Using the Install Wizard
To upgrade the firmware using the Install Wizard, follow the instructions in the Cisco Aironet Wireless LAN Client Adapters Installation and Configuration Guide for Windows (version -05) at the following URL:
To upgrade the firmware using ACU, follow these steps:
Step 1 Use the computer's web browser to access the following URL:
Step 2 Select Option #2: Aironet Wireless Software Display Tables.
Note You can download software from the Software Selector tool instead of the display tables. To do so, select Option #1: Aironet Wireless Software Selector, follow the instructions on the screen, and go to Step 7.
Step 3 Select Cisco Aironet Wireless LAN Client Adapters.
Step 4 Under Individual Files, find the client adapter firmware.
Step 5 Click the link that corresponds to your client adapter's model number (such as 340 or 350 series).
Step 6 Select the latest firmware file for your specific client adapter type (such as CB or MPI).
Note The firmware for PC, LM, and PCI cards is labeled PCMCIA-LMC-PCI, the firmware for mini PCI cards is labeled mini PCI or MPI, and the firmware for PC-Cardbus cards is labeled CB.
Step 7 Read and accept the terms and conditions of the Software License Agreement.
Step 8 Select the firmware file again to download it.
Step 9 Save the file to a floppy disk or to your computer's hard drive.
Step 10 Find the file using Windows Explorer, double-click it, and extract the image file to a folder.
Note To extract the file, click Browse on the WinZip Self-Extractor screen, select the folder where you want the file to placed, click OK and Unzip. After the file has been extracted, click OK to close the screen.
Step 11 Make sure the client adapter is installed in your computer and is operational.
Step 12 Open ACU and click the Load Firmware icon. The Load New Firmware screen appears (see Figure 1).

Step 13 Find the location of the new firmware in the Look in box.
Step 14 Click the firmware image file (*.img) so that it appears in the File name box at the bottom of the screen.
Step 15 Click the Open button. A progress bar appears while the selected image is loaded into the client adapter's Flash memory.
Step 16 Click OK when the "Firmware Upgrade Complete!" message appears. The OK button cannot be selected until the process is complete or an error occurs.

Technical Assistance Center
The Cisco TAC is available to all customers who need technical assistance with a Cisco product, technology, or solution. Two levels of support are available: the Cisco TAC website and the Cisco TAC Escalation Center. The avenue of support that you choose depends on the priority of the problem and the conditions stated in service contracts, when applicable.
We categorize Cisco TAC inquiries according to urgency:
•Priority level 4 (P4)—You need information or assistance concerning Cisco product capabilities, product installation, or basic product configuration.
•Priority level 3 (P3)—Your network performance is degraded. Network functionality is noticeably impaired, but most business operations continue.
•Priority level 2 (P2)—Your production network is severely degraded, affecting significant aspects of business operations. No workaround is available.
•Priority level 1 (P1)—Your production network is down, and a critical impact to business operations will occur if service is not restored quickly. No workaround is available.
Cisco TAC Website
You can use the Cisco TAC website to resolve P3 and P4 issues yourself, saving both cost and time. The site provides around-the-clock access to online tools, knowledge bases, and software. To access the Cisco TAC website, go to this URL:
All customers, partners, and resellers who have a valid Cisco service contract have complete access to the technical support resources on the Cisco TAC website. Some services on the Cisco TAC website require a Cisco.com login ID and password. If you have a valid service contract but do not have a login ID or password, go to this URL to register:
If you are a Cisco.com registered user, and you cannot resolve your technical issues by using the Cisco TAC website, you can open a case online at this URL:
If you have Internet access, we recommend that you open P3 and P4 cases through the Cisco TAC website so that you can describe the situation in your own words and attach any necessary files.
Cisco TAC Escalation Center
The Cisco TAC Escalation Center addresses priority level 1 or priority level 2 issues. These classifications are assigned when severe network degradation significantly impacts business operations. When you contact the TAC Escalation Center with a P1 or P2 problem, a Cisco TAC engineer automatically opens a case.
To obtain a directory of toll-free Cisco TAC telephone numbers for your country, go to this URL:
Before calling, please check with your network operations center to determine the level of Cisco support services to which your company is entitled: for example, SMARTnet, SMARTnet Onsite, or Network Supported Accounts (NSA).
