I have a some problems here, I hope I would be able to get some assistance here.
1st problem, my wireless connection,
I have no problem connecting to my wireless connection if I disable its encryption, but when I uses WPA AES encryption, I failed to connect to it. The network manager applet just shows the connecting animation (where the bottom circle is green while the top circle is grey). I doesn't feel secure if I leave my wireless connection unencrypted.
I am using
3com usb 3rcusb10075 wireless device, )already installed its driver using ndiswrapper with the inf and sys file from the windows firmware that comes with the CD.) and
Dlink DI-524 router.2nd problem, also wireless
even if I disable encryption, my unbuntu is able to get connected, but with no IP address, as I had disable DHCP, the only way I can get my connection to work is to disable encryption and enable DHCP. I try to insert the infor into etc/network/interfaces but after I set my wireless usb which is given the name eth1, then the wireless option will dissappear from the network-manager applet when I restart.
3rd problem, the "beep" sound.
every time, when there are errors, my system unit will unleash a "beep" sound, but my sound card are running without a problem, as I can hear the login music, and mp3 and etc. Some example of when the "beep" sound occurs are :-
i) when I open terminal, then I press backspace on the keyboard when there is nothing to back.
ii) when I entered the wrong user/password during login, then the message to tell me the error will show up right? but when that happens and I re-enter my username and password, each key that I press will result the "beep" effect.I just don't understand why it doesn't utilize my sound card to beep, but instead uses the motherboard to beep. Is this scenario normal? or there are some configuration that I need to play with.
Thanks for the help.
