Any place that Start is mentioned, tap the following Windows icon in the top, left corner of your CN3 desktop.
Chapter 5 — Network Support110 CN3 Mobile Computer User’s ManualWireless Network SupportRadios are installed at the factory and cannot be installed by a user. The CN3 must be serviced to install or replace radios. Contact your Intermec representative for more information. Personal Area Networks“Bluetooth” is the name given to a technology standard using short-range radio links, intended to replace cables connecting portable and fixed electronic devices. The standard defines a uniform structure for a range of devices to communicate with each other with minimal user effort. Its key features are robustness, low complexity, low power, and low cost. The technology offers wireless access to LANs, the mobile phone network, and the internet for a host of home appliances and mobile computer interfaces.Wireless Printing can also be done with Microsoft APIs, including Bluetooth extensions for Winsock, and Bluetooth virtual COM ports. Information about other Bluetooth software is in the Bluetooth Resource Kit and the Bluetooth Resource Kit User’s Guide via the Intermec Developer Library (IDL), which is available as a download from the Intermec web via www.intermec.com/idl. See your Intermec representative for information.Configuring with the Wireless Manager Note: Changes or modifications not expressly approved by Intermec could void the user’s authority to operate the equipment.Note: The Wireless Manager application is available only when Microsoft Zero Configuration is enabled. If Intermec Security is enabled, then this application is not available. See page 175 for information on enabling and configuring Microsoft Security.You can use the Wireless Manager to enable and disable Bluetooth, Wi-Fi, and the Phone if it is built into your CN3.To enable Bluetooth using the Wireless Manager•Tap Start > Settings > the Connections tab > the Wireless Manager icon, or • Tap the Wireless Manager row from the Today desktop.

Chapter 5 — Network Support116 CN3 Mobile Computer User’s ManualUsing the Wireless Printing AppletThe Wireless Printing applet separates the task of wireless printing from other Bluetooth management items not relevant to this task.Wireless Printing has a concept of the “current wireless printer.” This printer is the one to which the CN3 makes a connection when the wireless printing COM port is opened. If there is no current wireless printer, there is no wireless printing COM port. Registration and deregistration of this COM port is controlled by the Bluetooth COM port control. Use the Wireless Printing applet to handle the COM port registration. Customer software or other test applications can also use this applet to manage the COM port registration and deregistration.The current wireless printer is stored in the registry and is registered and deregistered on Bluetooth stack load/unload. If the current wireless printer changes, the existing wireless printing COM port is deregistered, and the new one is registered instead. The registered COM port is stored in the registry as the “WPort.”For information on using Bluetooth communications, see the Bluetooth Resource Kit in the IDL, which is available as a download from the Intermec web site at www.intermec.com/idl. Contact your Intermec representative for more information.Use any of the following methods to set the wireless printer:• Use a Bluetooth device search to locate the remote device.• Manually enter the remote Bluetooth Device Address.• Use Current Wireless Printer to set a different printer.

For help, see the Intermec Computer Command Reference Manual (P/N 073529) available online at www.intermec.com.Choosing Between Microsoft and Funk SecurityBefore you can implement a security solution on the CN3, you need to choose between Microsoft and Funk security:• By default, Funk security is enabled. It provides everything you get with Microsoft security plus Cisco Compatible Extensions features. It also provides additional authentication types like EAP-TTLS, LEAP, and EAP-FAST.• Microsoft security, with its Microsoft Zero Config feature, is also available. To switch to Microsoft security, go to “Configuring Microsoft Security” on page 175 to start.Configuring Funk SecurityYou can define up to four profiles for your Funk security. Different profiles let your CN3 communicate in different networks without having to change all of your security settings. For example, you can set up one profile for the manufacturing floor and one for the warehouse.Note: Your security choice does not depend on your authentication server. For example, you can choose Funk security if you use Microsoft Active Directory® to issue certificates.
Chapter 5 — Network SupportCN3 Mobile Computer User’s Manual 157To configure Funk SecurityUsing WPA SecurityWi-Fi Protected Access (WPA) is a strongly enhanced, interoperable Wi-Fi security that addresses many of the vulnerabilities of Wired Equivalent Privacy (WEP). Instead of WEP, WPA uses Temporal Key Integrity Protocol (TKIP) for its data encryption method. Currently, WPA satisfies IEEE 802.11i standards.WPA runs in Enterprise (802.1x) mode or PSK mode:• In Enterprise mode, WPA provides user authentication using 802.1x and the Extensible Authentication Protocol (EAP). That is, an authentication server (such as a RADIUS server) must authenticate each device before the device can communicate with the wireless network.• In PSK mode, WPA provides user authentication using a shared key between the authenticator and the CN3. WPA-PSK is a good solution for small offices or home offices that do not want to use an authentication server.To use WPA security, you need an access point with an 802.11b/g radio that supports WPA.1Select Start > Settings > the System tab > the Intermec Settings icon.2Tap (+) to expand Communications > 802.11 Radio > Funk Security.3Select an active profile, then configure its security settings.

This provides illegal users ways to mimic legitimate users and steal network resources and compromise security.Check Detect Rogue APs to detect and report client behavior suspected of being rogue APs. Once a rouge AP is detected, your CN3 no longer associates with that AP until you perform a clean boot.Clear Detect Rogue APs to solve AP connection problems that result when an AP gets put on the rogue list due to inadvertent failed authentications, not because it is a real rogue.• Mixed cell is a profile-dependent setting. If Enable mixed cell is enabled when you are using WEP, you can connect to access points that allow the optional use of encryption.• When using a wireless LAN that uses Cisco Access Points, a LEAP-enabled client device can roam from one access point to another without involving the authentication (RADIUS) server. If Allow fast roaming (CCKM) is enabled, an access point configured to provide Wireless Domain Services (WDS) takes the place of the RADIUS server (caching credentials of an initial authentication with the RADIUS server) and authenticates the client without perceptible delay in voice or other time-sensitive applications.• Check Enable Logging to log what activity occurs for this profile.

Chapter 5 — Network Support182 CN3 Mobile Computer User’s ManualLoading CertificatesIf you choose to use Transport Layer Security (TLS) with WPA or 802.1x security, you need to have a unique client certificate on the CN3 and a trusted root certificate authority (CA) certificate. If you choose to use PEAP, you need to load a root CA certificate. You can use a third-party CA to issue unique client certificates and a root certificate.To load certificatesWireless NetworkYour wireless adapter (network interface card) connects to wireless networks of two types: infrastructure networks and ad-hoc networks.• Infrastructure networks get you onto your corporate network and the internet. Using the 802.11b/g infrastructure mode, the CN3 establishes a wireless connection to an access point, linking you to the rest of the network.• Ad-hoc networks are private networks shared between two or more clients, even with no access point.Each wireless network is assigned a name (or Service Set Identifier - SSID) to allow multiple networks to exist in the same area without infringement.Intermec recommends using security measures with wireless networks to prevent unauthorized access to your network and to ensure your privacy of transmitted data. Authentication (cryptographically protected) by both the network and the user, transmitted data, and encryption are required elements for secure networks. Schemes are available to implement the features.• If your CA is on your WLAN, select Start > Settings > the System tab > the Certificates icon > the Root tab to view certificate details. • Press and hold a certificate, then select Delete to remove a certificate.
Chapter 5 — Network SupportCN3 Mobile Computer User’s Manual 183EncryptionAES (Advanced Encryption Standard)A block cipher, a type of symmetric key cipher that uses groups of bits of a fixed length - called blocks. A symmetric key cipher is a cipher using the same key for both encryption and decryption.As implemented for wireless, this is also known as CCMP, which implements AES as TKIP and WEP are implementations of RC4.CKIP (Cisco Key Integrity Protocol)This is Cisco's version of the TKIP protocol, compatible with Cisco Aironet products.TKIP (Temporal Key Integrity Protocol)This protocol is part of the IEEE 802.11i encryption standard for wireless LANs., which provides per-packet key mixing, a message integrity check and a re-keying mechanism, thus overcoming most of the weak points of WEP. This encryption is more difficult to crack than the standard WEP. Weak points of WEP include: No Initiation Vector (IV) reuse protection, weak keys, no protection against message replay, no detection of message tampering, and no key updates.WEP (Wired Equivalent Privacy) encryptionWith preconfigured WEP, both the client CN3 and access point are assigned the same key, which can encrypt all data between the two devices. WEP keys also authenticate the CN3 to the access point - unless the CN3 can prove it knows the WEP key, it is not allowed onto the network. WEP keys are only needed if they are expected by your clients. There are two types available: 64-bit (5-character strings, 12345) (default) and 128-bit (13-character strings, 1234567890123). Enter these as either ASCII (12345) or Hex (0x3132333435).Key Management ProtocolsWPA (Wi-Fi Protected Access)This is an enhanced version of WEP that does not rely on a static, shared key. It encompasses a number of security enhancements over WEP, including improved data encryption via TKIP and 802.11b/g authentication with EAP. WiFi Alliance security standard is designed to work with existing 802.11 products and to offer forward compatibility with 802.11i.WPA2 (Wi-Fi Protected Access)Second generation of WPA security. Like WPA, WPA2 provides enterprise and home Wi-Fi users with a high level of assurance that their data remains protected and that only authorized users can access their wireless networks. WPA2 is based on the final IEEE 802.11i amendment to the 802.11 standard ratified in June 2004. WPA2 uses the Advanced Encryption Standard (AES) for data encryption and is eligible for FIPS (Federal Information Processing Standards) 140-2 compliance. AuthenticationEAP (Extensible Authentication Protocol)802.11b/g uses this protocol to perform authentication. This is not necessarily an authentication mechanism, but is a common framework for transporting actual authentication protocols. Intermec provides a number of EAP protocols for you to choose the best for your network.EAP-FAST (Flexible Authentication via Secure Tunneling)A publicly accessible IEEE 802.1X EAP type developed by Cisco Systems. It is available as an IETF informational draft. An 802.1X EAP type that does not require digital certificates, supports a variety of user and password database types, supports password expiration and change, and is flexible, easy to deploy, and easy to manage.
Chapter 5 — Network Support184 CN3 Mobile Computer User’s ManualLEAP (Lightweight Extensible Authentication Protocol)Also known as Cisco-Wireless EAP, provides username/password based authentication between a wireless client and a RADIUS server. In the 802.1x framework, traffic cannot pass through a wireless network access point until it successfully authenticates itself.EAP-PEAP (Protected Extensible Authentication Protocol)Performs secure authentication against Windows domains and directory services. It is comparable to EAP-TTLS both in its method of operation and its security, though not as flexible. This does not support the range of inside-the-tunnel authentication methods supported by EAP-TTLS. Microsoft and Cisco both support this protocol.EAP-TLS (Transport Layer Security)Based on the TLS (Transport Layer Security) protocol widely used to secure web sites. This requires both the user and authentication server have certificates for mutual authentication. While cryptically strong, this requires corporations that deploy this to maintain a certificate infrastructure for all their users.EAP-TTLS (Tunneled Tr a n s po r t L a ye r Security)This protocol provides authentication like EAP-TLS (see page 167) but does not require certificates for every user. Instead, authentication servers are issued certificates. User authentication is done using a password or other credentials that are transported in a securely encrypted “tunnel” established using server certificates.EAP-TTLS works by creating a secure, encrypted tunnel through which you present your credentials to the authentication server. Thus, inside EAP-TTLS there is another inner authentication protocol that you must configure via Additional TTLS Settings.Authentication (continued)
