What can I do to fix this?
I used to have archbang and it worked fine.
It is a belkin N

Re: [SOLVED]Crunchbang not detecting my wireless card

I'm assuming that's a USB adapter? Use lsusb to identify the adapter. Then use lsmod to make sure the kernel module is loaded. If it doesn't look like any related modules are loaded, then use apt-get or synaptic to install the proper driver from the repos.

Re: [SOLVED]Crunchbang not detecting my wireless card

Gods bless my recent spate of bad luck with wireless devices!  I think you may be able to take a shortcut here.

I did lsmod and I was able to find the belkin wireless usb adapter in the list

Then i used lsmod and I have no idea what I'm trying to look for =/

What does `lsusb` give you?  Please post the output here.

Re: [SOLVED]Crunchbang not detecting my wireless card

Looks like you're in luck - RTL8188SU is supported in Squeeze!  Looky here.  You'll need a hardwire internet connection...

Remember that you need to prepend "sudo" to any line shown on that page with a hash prompt.

Lol um a hardwire internet connection isn't possible atm

I have a USB so I can transfer files if that helps?
Is there anyway I can do this with a USB of off Windows?

Re: [SOLVED]Crunchbang not detecting my wireless card

Sure!  Ya see the links for firmware-realtek and wireless-tools?  Follow them and grab the .deb files for those from the Squeeze repo.  (Might as well make that squeeze-backports for firmware-realtek).  If you don't have zip (`which zip` in a terminal window will return nothing if it isn't installed) go ahead and grab that too, as well as the dependencies for wireless-tools just in case they're not already in the base CrunchBang install.  Open the USB drive in Thunar and click on the .deb files individually - gdebi should automatically launch and install them.

The wget section is specifically for the RTL8192U devices; you shouldn't need to worry about that part.

ACTUALLY i'm retarded wait

I go here
http://packages.debian.org/firmware-realtek
Thenn I'm going to assume I click the one that says

squeeze (stable) (kernel): Binary firmware for Realtek wired and wireless network adapters [non-free]
0.28+squeeze1: all

Then I get to this page
http://packages.debian.org/squeeze/firmware-realtek

Then i THINK I click all under architecture
I get to this site
http://packages.debian.org/squeeze/all/ … k/download
Then, I'm in north america so I click
http://http.us.debian.org/debian/pool/n … e1_all.deb

And i download that. Was that the correct method?

Sometimes you might need to reboot for these changes to take effect.

What does `iwconfig` show at this point?

I need to know which kernel you are running:
Post output of

uname -r

If possible, output of

dmesg | grep -E -i 'firm|wlan|real'
lsmod

Re: [SOLVED]Crunchbang not detecting my wireless card

Actually, last night, I restarted my computer and I saw that it connected but I never actually tried to go to a website.
I tried to install google chrome and it didn't install, there were errors
So I tried to run iceweasel but it doesn't connect to any website =/

Re: [SOLVED]Crunchbang not detecting my wireless card

I can not find any errors in what you published.
I think network config is OK.
There might be a problem with the resolver.
Try using OpenDNS name servers, as specified here:  http://crunchbanglinux.org/forums/post/160604/#p160604
PS: use geany or your own preferred editor in stead if gedit.
Save the file and reboot (not strictly necessary - restarting the network is probably enough)
Check /etc/resolv.conf
the 2 name servers you added to the config file should be there.

If you still can not connect to the network, install rfkill and see if it is blocked:
sudo apt-get install rfkill
sudo rfkill list


If there are soft blocks, you can remove them with

sudo rfkill unblock ...

see man rfkill for the syntax

hth

If you poke the bear it is going to come after you.
