couldn't browsing the internet by built-in wifi ( 5100AGN)
 

Recently I installed a backtrack 4 final on my computer, but I couldn't browse the internet by wifi , when I use the slax networktool to analyze the newwork and see what the problem is, the tools showed as below:
wpa-supplicant:error while loading shared libraries: libssl.so.0: cannot open shared object file: No such file or directory
I also cann't find the libssl.so.0 in the corresponding diretory.
I'm a freshman and could anyone help me how to sovle the problem,the better, the more detailed,thanks a lot anyway.

I read somewhere on the backtrack site that networking was off by default. Turn it on by executing the command: /etc/init.d/networking start

Yes, what you said is right:the NetworkManager is closed by default, but I had opened it by executing the same command as you: /etc/init.d/NetworkManager start, meanwhile its icon became green(showed it is opened), then I configured the networkmanager in detailed(tried few times), but it still told me the internet was disconnected, my god,I didn't know why and how slove it, any idea about this problem,thanks you anyway.

The next question would be ... do you have the correct wifi drivers installed? Use lspci or lsusb to find out what wifi card your box has and search through add/remove software to see if the drivers are installed. I haven't tried backtrack yet so I don't have a how-to for you. It's based on Ubuntu so I'm assuming the search for drivers should be straight forward, but I'm guessing.

I have tried to check if my wifi card works in the right way by command iwconfig and iwlist, it seems it works right, for I can see other APs. My wifi card is built-in,so lspci and lsusb don't work at all,I have read a lot about the problem, I gusess it may be caused by lacking the file libsll.so.0,which is integrated in wpa-supplicant.lzm. Luckily, I have found such file on the webside www.slax.org, and downloaded it. But, disappointedly, I don't know how to install it under condition of Backtrack, because I downloaded it in Windows, and ,as to me, it is big different between these two operating system. Is anyone can help me to install the software in Backtrack,thanks anyway.

You wifi card will show up in either lspci or lsusb, mine show up in lspci:

06:00.0 Network controller: Broadcom Corporation BCM4322 802.11a/b/g/n Wireless LAN Controller (rev 01)

If you having problems with a wifi card, you need to know which one you have to make sure you have the correct driver running. Sorry, but you lost me with that file your trying to install, maybe someone else has info for you.

yes, I can see wifi card by using command lspci, however there is no mention its driver installed or not. So I downloaded the wpa-supplicant.lzm and zz_compat-wireless-ar9170-3.27-bt4.lzm and placed them under the folder of modules according to the installation specification of them. Then I reboot my computer and it works in this way. The computer can be linked to internet and I can browse the website without any problem. And thanks a lot for your help.
