I'm using Ubuntu 12.04. I have a problem with my wifi, but not always. My system detects wifi networks some times and display it in the available wifi networks list and is able to connect properly. But, some times it doesn't detect available wifi networks at all.
Can any tell me a way to make Ubuntu look for available wifi networks?
Here is the
