Chapter 6 — Troubleshooting and Maintaining the CK30

Problems With Wireless Connectivity

Problem

When you turn on the CK30 after it was suspended for a while (10-15 minutes or longer), it can no longer send or receive messages over the network.

The no network connection icon

( )appears on the status bar.The CK30 is not communicating with the access point.

The CK30 is connected to the DCS 30X or Intermec Gateway or host computer and you move to a new site to collect data. The network connection icon was visible but now the no network connection icon ( ) is visible.

The network connection icon is in the status bar, but you cannot establish a terminal emulation session with the host computer.

Solution

The host may have deactivated or lost your current terminal emulation session. In a TCP/IP direct connect network, you need to turn off the “Keep Alive” message (if possible) from the host so that the TCP session is maintained while a CK30 is suspended.

The CK30 is not connected to the access point. Make sure the access point is turned on and operating. You may also be using the CK30 out of range of an access point. Try moving closer to an access point to re- establish communications.

Make sure the CK30 is configured correctly for your network. The radio parameters on the CK30 must match the values set for all access points the CK30 may communicate with. For help, see “Configuring 802.11b/g Radio Communications ” on page 41.

If you have an 802.11b radio, the radio initialization process may have failed. Try resetting the CK30. See “Booting the CK30” on page 102.

If you have tried these possible solutions and the no network connection icon still appears, you may have a defective radio card. For help, contact your local Intermec service representative.

You may have gone out of range of an access point. Try moving closer to an access point or to a different location to re-establish communications. Once you are in range again, the network connection icon appears again. Any data you collected while out of range is transmitted over the network.

There may be a problem with the host computer, a problem with the connection between the DCS 30X or Intermec Gateway and the host computer, or a problem with the connection between the access point and the host computer. Check with your network administrator to make sure the host is running and allowing users to login to the system.
