Comment 1 for bug 395919

I'm using Asus K50IN notebook pc. Ubuntu 9.04 is running. Wireless signal strength looks low and wireless connection drops too often and is not reconnecting automatically. My network connection is quite unstable.

I had installed linux-backports-modules-jaunty package.

I see many tickets which are similar to my problem. Is there a solution that is fixing this problem?
