    wireless and ethernet running but not connecting

    Hey !

    im running an ubuntu 12.04 realease on my hp pavillion dv6 and i am having problems in connecting to the internet (both ethernet and wireless). i did some checking and the results are shown below . I can see the wireless on the ethernet card accepts the lan cable, i can also see the available connections. But, i am not able to connect to any of them . it tries to connect, times out , tries again times out again and so in.
    rfkill list all

    Re: wireless and ethernet running but not connecting

    UPDATE : i went to my university to test the wireles connection. at first it did not connect. then i went to EDIT CONNECTIONS and removed all the wired and wireless connected and then reconnected to the university`s internet by creatiing a brand new connection. i was able to access the wireless but not the ethernet connection.

    I then went back home and tried the same thing again , but it did not work. I could access the SAME wireless connection at home from a different computer and via my phone ( Samsung Galaxy S3 )
