Since access points are generally secure, they will most likely not be listed here. By default, the unit attempts to connect to preferred net-works. This behaviour can be changed by enabling (√) ‘Automatically connect to non-preferred networks’ in the Advanced dialogue box (page 118).•To add a new conﬁguration, tap the <Add New> button. A blank Wireless Properties dialogue box is displayed.5.

The Network name ﬁeld can contain a maximum of 32 characters. The name assigned here is listed as a preferred network.Important: Keep in mind that the WORKABOUT PRO will only communicate with access points that are conﬁgured with the same SSID.

If you are not using encryption, you can choose ‘Disabled’ from the dropdown encryption menu. Otherwise, leave this ﬁeld as is.Authentication802.11b supports two subtypes of network authentication services: Openand Shared. Under Open authentication, any wireless station can request authentication. The station that needs to authenticate with another wireless station sends an authentication management frame that contains the identity of the sending station. The receiving station then sends back a frame that indicates whether it recognizes the identity of the sending station. Under Shared authentication, each wireless station is assumed to have received a secret shared key over a secure channel that is independent from the 802.11b wireless network communications channel.Network Key:This text box is used to specify a 5 or 13 ASCII character sequence or an equivalent 10 or 26 Hexadecimal digit sequence that matches the active WEP key on the access point.

It provides authentication for user devices attached to an Ethernet network, whether wired or wireless. A security protocol packet such as TLS or MD5 encapsulated in an “EAP” is used in conjunction with the “802.1x” standard to authenticate users at the MAC layer. Available EAPs are listed in the dropdown menu next to the ‘EAP’ option.• To activate “802.1X”, tap the stylus in the checkbox next to ‘Enable 802.1x authentication’ to enable (√) it.EAP Type (Extensible Authentication Protocol):This dropdown menu lists the EAP types available on your system. The items in this dropdown menu will vary depending on your network setup. Keep in mind also that some authentication protocols require that you select a ‘Certiﬁcate’. By selecting the Properties button, you will be able to select a Certiﬁcate. “Certiﬁcate Assignment” on page 77 provides a website that outlines how to create certiﬁcates for your network.6.

Psion Teklogix WORKABOUT PRO Hand-Held Computer User Manual 117Chapter 6: Connecting To A LAN With 802.11bAssigning An IP AddressThe connection you created will be listed in the Wireless Information tab as a preferred network. The radio will search for the SSID and will compare the WEP and authentication information you speciﬁed. If there is a match between your WORKABOUT PRO settings and the access point settings, the WORKABOUT PRO will communicate on the network through the access point.6.2.2 Assigning An IP AddressIf your network is not using a DHCP server, you will need to assign an IP address.• In the NETWLAN1 Settings window, display the IP Information tab.Figure 6.11 IP InformationNote: Tapping on the <Renew> button forces the WORKABOUT PRO to renew or ﬁnd a new IP address. This is useful if, for example, you are out of com-munication range for a longer period of time and your hand-held is dropped from the network.• Tap on the <Conﬁgure...> button to deﬁne a static IP address.Figure 6.12 Deﬁning An IP Address
