Connected wireless, but not connected wireless? (solved)

I just installed Crunchbang, and I can connect to the internet. But when I tried to use the start up script or tried to access anything that needed the internet, it wouldn't work. (It says I'm connected, but that's apparently not the case)

Output of

uname -rv
lspci -knn | grep -EiA2 net
dmesg|grep -Ei 'wlan|firmw|dhc'

is

crunchbang@crunchbang:~$ uname -rv

Not sure if I need certain drivers or what. I have to be wired to access the internet.

Re: Connected wireless, but not connected wireless? (solved)

it look like you should be good to go...
what is the output these commands?

ping -c3 8.8.8.8
ping -c3 www.google.com

also, sometimes can be a problem with the router, have you tried to disconnect all your devices and restart it!?

lastly, check my signature...

Look at my body paragraph again, I just edited it. I accidentally posted the WIRED output instead of the wireless. NOW it's the wireless, lol. xD

Re: Connected wireless, but not connected wireless? (solved)

^ I am pretty sure that I have read wlan-related info also in your original post...anyway you have loaded the correct modules for your device and the output of dmesg looks OK...

please, post here the output of the commands from my previous reply (and maybe try to restart the router)...
if you use the [code  ] tags, the output is more readable, see the commands between the text editor box and the smileys...

Re: Connected wireless, but not connected wireless? (solved)

Commands before and after I reset the router:

crunchbang@crunchbang:~$ ping -c3 8.8.8.8
PING 8.8.8.8 (8.8.8.8) 56(84) bytes of data.

--- 8.8.8.8 ping statistics ---
3 packets transmitted, 0 received, 100% packet loss, time 2016ms

crunchbang@crunchbang:~$ ping -c3 www.google.com
ping: unknown host www.google.com

Still doesn't work.

Re: Connected wireless, but not connected wireless? (solved)

Everything works, like if I got onto Windows 7. It'd work fine, and it works fine with all other devices. Could it be a driver problem?

Re: Connected wireless, but not connected wireless? (solved)

you already have the correct driver for your device, try

sudo dhclient wlan0

crunchbang@crunchbang:~$ sudo dhclient wlan0
[sudo] password for crunchbang: 
RTNETLINK answers: File exists

That's what I got when I ran it.

ElectricCharge, as far as my experience in these forums tells me, bumping is OK but you should try to do it while you're adding more information in order to help people in helping you...also remember that the help you get is a result of people volunteering their time, 15 min might seem like a lot of time for you but it might not necessarily be for someone else...

anyway, let's see if this gets you online...

sudo ifdown wlan0 && sudo ifup wlan0

Re: Connected wireless, but not connected wireless? (solved)

Sorry about that, I'll be sure to remember that next time

I ran

sudo ifdown wlan0 && sudo ifup wlan0

and got

crunchbang@crunchbang:~$ sudo ifdown wlan0 && sudo ifup wlan0
[sudo] password for crunchbang: 
ifdown: interface wlan0 not configured
Ignoring unknown interface wlan0=wlan0.

Re: Connected wireless, but not connected wireless? (solved)

ok, so check your /etc/network/interfaces file, it should contain something like

allow-hotplug wlan0
iface wlan0 inet dhcp

if not, add those lines and reboot...

you can post the content of the file here if you're not sure and/or you want a double check....

Re: Connected wireless, but not connected wireless? (solved)

As you see, others are having this issue: http://crunchbang.org/forums/viewtopic.php?id=28884

I suspect that it could be a authentication issue. What kind of security do you use? WPA/WPA2, WEP?  Try turning off the security on your router for short time, then edit your connection to use "none" as wifi-security. If this works, then the issue is authentication, and you may have to change your wifi-security from wep to wpa/wpa2 or vice versa. If it doesn`t connect without security, then the issue is elsewhere, and my guess is wrong... But it`s worth a test...

I now cannot not even connect to the router (Even if it doesn't work) it says "device not managed"

I think I may have put it in incorrectly. This is what the file says.

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback
allow-hotplug wlan0
iface wlan0 inet dhcp

Here`s my output and my wifi is working:

I'll try this if the change of the /etc/network/interfaces doesn't work. (I would need to reset my router to factory defaults, since I change the wifi password to something else and forgot. Of course, I still know the security code to connect a device to it.)

I reinstalled Crunchbang a few times, and it's now working. For some reason, Crunchbang thought it was WPA instead of WEP.

It is good that you finally managed to get the connection working...

please, edit the title of your first post adding a heading [SOLVED]...
