Now with Thomson TCW710 you can see wirelesses network but when you click on it after inserting password it seems to be connecting but after a while is asking for password again and eventually no connection ( wirrelles is working perfectly on ipod tauch).

    Code:
    $ ifconfig
    eth0 Link encap:Ethernet HWaddr 00:8c:fa:27:e8:ff
    inet addr:192.168.0.16 Bcast:192.168.0.255 Mask:255.255.255.0

    lo no wireless extensions.

    eth0 no wireless extensions


    Right now I'm visiting parents for a week and time is limited, so please-please help.

    So what kind of wireless device is it?
    Code:
    lspci -nn | grep 0280
    Is the behavior improved if you detach the ethernet first?

    Hi chili555,
    Thank you for replying!
    If I unplug wired there is no changes.

    $ lspci -nn | grep 0280

    I suggest you hook the ethernet back up and install the Ubuntu-ized version of compat-wireless. It seems to solve a lot of problems in these Real-hecks.
    Code:
    sudo apt-get install linux-backports-modules-cw-3.6-precise-generic
    After it's installed, detach the ethernet, reboot and let us hear your report.

    Did that. Unfortunately it is the same: taking password - connecting - and asking for password again.
    Thank you

    I assume this is using the driver rtl8192ce; verify:
    Code:
    lsmod | grep rtl
    If so, let's try a driver parameter:
    Code:
    sudo modprobe -r rtl8192ce
    sudo modprobe rtl8192ce swenc=1
    If it works, write one file. CAUTION: don't blindly write the file unless it dramatically and perfectly works!
    Code:
    gksudo /etc/modprobe.d/rtl8192ce.conf
    Add one line:
    Code:
    options rtl8192ce swenc=1
    Proofread, save and close gedit.

    EDIT: Off for the evening; see you tomorrow.

    Did this:
    maria@maria-Satellite-C855D:~$ lsmod | grep rtl
    rtl8192ce 53544 0
    rtl8192c_common 48369 1 rtl8192ce
    rtlwifi 74719 1 rtl8192ce
    mac80211 557654 3 rtl8192ce,rtl8192c_common,rtlwifi
    cfg80211 219204 2 rtlwifi,mac80211
    compat 20099 8 lib80211,rtl8192ce,rtlwifi,mac80211,cfg80211,bnep, rfcomm,bluetooth
    maria@maria-Satellite-C855D:~$ sudo modprobe -r rtl8192ce
    [sudo] password for maria:
    maria@maria-Satellite-C855D:~$ sudo modprobe rtl8192ce swenc=1
    maria@maria-Satellite-C855D:~$

    No changes. So I didn't go further.
    Thank you

    Since the behavior changed with a new router, let's see what changed there. May we see:
    Code:
    nm-tool
    Is the cable-modem set to WPA2 only or the dreaded WPA and WPA2 mixed mode?

    Dear chili555!

    Somehow router was reset to defolt setting and i have wireless connection.
    I think security setting screwed that.

    So I thank you very-very mach for time, energy.

    And I apologize for taking your time. I really appreciate your effort.

    THANK YOU!
