2. A keyboard or SSH connection.

Instructions

Set up a default network interface for DLI/Ion tablets

On a freshly imaged tablet, the default (always in use) interface in YaST will be set to wireless. This will be the typical setup for communities. To change the default interface:

1. Attach a keyboard (or SSH) to a powered-on tablet and press Ctrl+Alt+F1.
2. Enter in login information. If doing this over the phone for a community, use "networkconfig" for both the username and password.
      *Enter "yast lan" in the command-line if necessary.*
3. On the "Overview" tab, press the Tab key to highlight the desired default interface.
4. Press Alt+i to edit the new default interface. Press the left arrow key to navigate to the "General" tab.
5. Tab to the "Activate Device" box. Press the down arrow key to change "Manually" to "At Boot Time" and press Enter.
6. Press Alt+n to navigate to the next window. If a wireless device was chosen, enter in Wi-Fi settings.

• Enter the SSID of the wireless network provided by the community
• Set encryption type to "WPA-PSK (WPA version 1 or 2)"
• Tab to hightlight “Encryption Key” field
• Enter the Encryption Key provided by community
• *NOTE – The characters will appear as asterisks while entering the Encryption Key. Be careful to enter the correct characters
• Press Alt+n

7. Once back at the "Overview" tab, press the Tab key to highlight the network interfaces, and press the down arrow to highlight the other interface that was not chosen in Step 3. Press Alt+i to edit the interface.
8. Press the left arrow key to highlight the "General" tab. Press Tab to highlight the "Activate Device" box.
9. Press the down arrow and choose the option that says "Manually." Press the Enter key to accept the change. Press Alt+n to move to the next pane.
10. Press Alt+o to save the settings.
11. Exit the shell by pressing Ctrl+Alt+F7.

Configure network settings on interfaces

Beginning with OS Image 6.1.0, it is now a requirement for the tablet to use DHCP. This comes on the tablet by default. The only thing that needs added is the wireless password, encryption type, and SSID for the wireless interface. If a community requires static IP addresses, suggest using a MAC address reservation. Once settings in YaST are saved, this will bring up both interfaces, which can be viewed with "ifconfig." A reboot will fix this issue.

Switch to the other network interface while in use

Beginning with OS Image 6.1.0, a new feature has been added that will toggle the active network interface from the tablet's default "always in use" interface. This is so Support can ask the end user to switch the interface from wireless to the wired dock connection, or vice versa.

1. Press the left-most button on the front of the DLI tablet or the "+" button (Volume Up) on an POS-X Ion 8. A dialog window will appear and ask the user if they want to switch to the (non-default) interface.
2. Press the "Yes" button to switch interfaces, or press "No" to Cancel.
3. If "Yes" was selected, the dialog box with show a progress bar along with updates to show the user it is currently working. This will also show error messages, if any.
4. The new interface will now be active. This is only a temporary change, a reboot will always boot the default interface selected in YaST.
