    Default I see wifi networks but does not connect

    My noteBook is accessing the wifi networks but does not connect.
    See the result below:

    Code:
    asus:/home/sergio # /usr/sbin/iwconfig
    lo        no wireless extensions.
    
    wlan0     IEEE 802.11bgn  ESSID:off/any  
              Mode:Managed  Access Point: Not-Associated   Tx-Power=20 dBm   
              Retry short limit:7   RTS thr:off   Fragment thr:off
              Encryption key:off
              Power Management:off
              
    eth0      no wireless extensions.
    I do not know what to do with this information.
    Please, could you help?

    Default Re: I see wifi networks but does not connect

    I detected something strange: The notebook can connect with the wi fi of my cell phone
    Is it possible for a noteBook to connect to a router from a mobile phone and can not connect to the router of a modem?
    I have another macchines like a netbook, two cellphones and a PC and they all connect to the modem without any problems.
    So I think the fault is not from the modem
    Please, any idea?

    That can depend on the WPA/WPA2 implementation on the router itself. Some were faulty. Mixed mode did not work, had to drop back to only WPA, some to WEP, not a good security solution.

    If that is the case, you are better off getting a newer modem/router, or have the modem/router set to bridge mode (just pass-through) with wifi disabled and run a better 2nd router off of it.

    fwiw (observation)

    if signal strength is shown as below 60% a reliable wifi connection cannot be established

    if below 50% its impossible

    an HP-Pavilion laptop internal wifi does not work in some home locations. When a usb Logilink WLD151 is plugged in, there is never a problem
