WL300G loses connection only once each session

Hi folks,

My 300 works fine, got not the real latest firmaware, reasen see firmware topic.
Got only one minor problem:

When the session starts the lan card connects to de WL300G, makes connection and discard it after a few minuts. :(
I've find out that when I disconnect the network en connect it again the connection stays a live the whole time :) until de laptop is off. Start a new session the problem is there again. :confused: :confused: It's not a realy big deal but somtimes inconfined if youre chatting.

Does any one knows this problem wish I heart also accours with the WL500G.
