Hi to Everyone,
On the Desktop of my association, there was no wireless card. So, I
purchased one that is said to be Debian compatible. It is a PCI card
TP-LINK
TL-WN751ND
It is supposedly based on an Atheros chipset AR 9227
I plugged it inside the Central Unit on a PCI slot, and then booted
the Debian Squeeze system.
As a rather pleasant surprise, the wireless system was being
acknowledged immediately, and I could display a list of wireless
networks available in my area, amongst which I saw my own DSL wireless
network on which I have been able to connect any other laptop or
desktop computer that ever came to my house. I clicked to that Network
on the list, and then entered all the digits of my WPA password. This
being done, I got the message that I was connected and that the
connexion was allright. Well, then I launched Firefox (I mean
Iceweasel) and called for a web page... As soon as the connexion to
that page was achieved, THE SYSTEM FROZE and I could do nothing
more... The mouse was no longer active, same for the keyboard or
anything else, CTRL-ALT-DEL did nothing, and I had no other choice
than disconnecting power. At reboot, the freezing did appear right
away, in the process of gnome launching. Same at each new attempt.
I first thought that the chipset may have been faulty or damaged. So I
tested it under MSWIN (XP) since I have a dual boot on that desktop.
Under MSWIN, after the appropriate install with the provided CDROM,
the TL-WN751ND card did operate all right. After the password was
typed, connexion happened and operated without freezing the system or
any other trouble. So, it is most likely that the hardware is not
faulty here.
I understand that I should probably have first checked if my Debian
Squeeze system was ready with the appropriate packages to run that
wireless chipset, instead of right away trusting the fact that it
seemed to be reckognized 'out of the box'. However, now that things
are that way, I wonder what files I should delete (booting from a
rescue disk maybe), so that I am able to de-install or install
whatever is needed to get that chipset working.
Thanks in advance for your help
P.S. : I carried new tests. As said above, now that my WiFi is
configured, every attempt to boot, leads to "freezing" of the system in
the middle of gnome start... EXCEPT IF I shutdown my DSL/WiFi box ! As
long as no connexion is possible, the system starts all right ; I can
see the other WiFi available in the area (I don't have the
passwords...). This being, if I reboot my WiFi connexion on the DSL
modem, then, as said before, connexion does happen all right, it seems
fully operational, but only for about 45 to 60 seconds, system freezing
happens next. My TL-WN751ND card is supposed to work with Debian kernel
module ath9k, which is supposed to be loaded with the wireless-tools
package, which is alreeady installed.
