wireless centrino intel 2100

Hello, I have a Compaq x1050 with suse 9.2. I have sucessfully configured a wireless connection, but it only operates once after linux is booted. If the connection is dropped, for example using rcnetwork restart it will not go up again. Only after rebooting. I suspect that it is related to the firmware image that must be loaded into the wifi card when the driver is initialized. Can anybody help me? Flavio Arthur Ferreira
