It might be that the Operating System is preventing connection to the router because:
- the network is unsecured. look for the "Connect Anyway button";
- the Amilo's WiFi is set to a manually configured IP address, pls try "Obtain an IP address automatically" in the Internet Protocol (TCP/IP) Properties of the Wireless Network Connection of the Control Panel/Network Connections;
- it maybe that your Amilo has its own WiFi configuration and if so, you should disable the OS to manage your wireless connection.
Incidentally, you could try downloading a third party Wireless network detection software that is to verify that the Amilo's wireless card is working and that it can sense the Wireless router. An example would be NetStumbler
Hope this be of initial help/idea. Pls post back exact model number of the Amilo laptop, how things turned up or should you need additional information.
Good luck and kind regards. Thank you for using FixYa.
