Odyssey Client is an enterprise-class 802.1X access client that provides to protect your network. It came with my Dell Axim to provide security when accessing a secure network. It's mainly there to authenticate to a RADIUS server should I be so inclined.
Your computer should only use the default connections you made, not the Odyssey miniport connections. The miniport connections will act as a pass-through in case you decide to use the Odyssey client. This is similar to the Cisco VPN adapter I have installed on my laptop, except Windows thinks the VPN adapter is an actual network card, and it only becomes enabled when I use the VPN client.
Can you go into Add/Remove programs and remove the Odyssey client? You might try that and see if it helps. Are you using any sort of encryption security (WEP/WPA) on your wireless router and haven't set it up properly on the laptop?
If you do have any inclination to readup on the Odyssey client, you can find it at
