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 iwconfig
info
ppp0 no wireless extensions.
lo no wireless extensions.
wwan0 no wireless extensions.
eth1 IEEE 802.11abg ESSID:off/any
Mode:Managed Access Point: Not-Associated
Retry long limit:7 RTS thr:off Fragment thr:off
Power Management:off
eth0 no wireless extensions.
