Getting wireless to work [SOLVED]

hermanningjaldsson · 2011-06-25 18:39:51

i just installed arch linux.
core, x86-64.
i took care to install the wireless packages as well.

i can detect my wireless card by typing:
lspci | grep -i net
and then i get:
05:00.0 Ethernet controller: Broadcom Corporation NetLink BCM5906M Fast Ethernet PCI Express (rev 02)
06:00.0 Ethernet controller: Atheros Communications Inc. AR5001 Wireless Network Adapter (rev 01)

So how do i connect to the internet wirelessly from now on?

Always hit the wiki first.

https://wiki.archlinux.org/index.php/Broadcom_wireless

https://wiki.archlinux.org/index.php/Wireless_Setup

hermanningjaldsson · 2011-06-25 19:35:04

im here:
https://wiki.archlinux.org/index.php/Broadcom_wireless

since i have a:
05:00.0 Ethernet controller [0200]: Broadcom Corporation NetLink BCM5906M Fast Etnernet PCI Express [14e4:1713] (rev 02)

my card is not listed anywhere,.
that means i have a b43/b43 legacy.
but since my type can neither be found under the b43 or b43 legacy, how do i find out which one it is?

Gooru · 2011-06-25 20:54:18

Can't you just try both?
I learnt faster, because of making mistakes and spending time trying to fix all of them. IMHO that's the best way to explore your os.

anonymous_user · 2011-06-25 20:59:24

Isn't Atheros Communications Inc. AR5001 (not the Broadcom) your wireless?

Um, that would be your wired Ethernet. It will show up if you use ip link. Or, using the deprecated method, ipconfig -a

As to the wireless, anonymous_user is correct.

hermanningjaldsson · 2011-06-26 08:55:17

can anybody help me with getting this wireless to work?

the manual is telling me to installa modules, but off course i cant do that because i dont have wireless.

I thought we were.

Unfortunately, you have some wrong ideas about your system. We have pointed that out to you, but you have acknowledged nothing.

Your system does not have a Broadcom Wireless.
Your system does not use b43.
Did you read the link provided by anonymous_user?

I think the drivers may already be installed. If they are not, there exists a plan B; you will need to find a way to import the packages using a disk, or by chrooting from a live cd of a distribution that will provide wireless access.

hermanningjaldsson · 2011-06-26 16:32:00

yes and thanks for the help.

i did go over that link, and had a hard time using it to achieve my end.

how can i find out if the drivers are already installed?

ewaller · 2011-06-26 16:55:23

The command lsmod will show you the installed modules.
Also, can you post the output of ip link ?? If that does not work, then the output of ifconfig -a ??

Lastly, just to be certain of the driver, can you post the output of lspci -nn | grep Wireless ??

hermanningjaldsson · 2011-06-26 17:14:05

ip link didnt work.
ifconfig -a gave me:

eth0
.....

lo
....

wlan0
Link encap: Ethernet HWaddr 00:1F:3A:BC:40:84

lspci -nn | grep Wireless:

ewaller · 2011-06-26 17:36:41

Okay, so you have a wireless card and it is seen by the system

What happens if you try iwlist scan ??

hermanningjaldsson · 2011-06-26 17:44:42

iwlist scan:

lo Interface doesnt support scanning.

eth0 Interface doesnt support scanning.

wlan0 Interface doesnt support scanning : Network is down.

ewaller · 2011-06-26 17:50:24

Okay, we are making progress. Try (as root) ifconfig wlan0 up then try the iwscan list

If there are problems with that, post the output of rfkill list (I hope it is installed)

hermanningjaldsson · 2011-06-26 18:00:42

to do something as root, hmm.
i am root@myhost, i guess that means im doing things as root.

ifconfig wlan0:
wlan0
Link encap:Ethernet HWaddr 00:1F:3A:BC:40:84
BROADCAST MULTICAST MTU:1500 Metric:1

TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:0 (0.0 b) TX bytes:0 (0.0 b)

iwscan list:
-bash: iwscan: command not found

hermanningjaldsson · 2011-06-26 18:02:03

ok now i did
ifconfig wlan0 up.

that just went, no response.

ewaller · 2011-06-26 18:06:30

I said

then try the iwscan list

I need more coffee. The command, of course, is iwlist scan. Since the network did not complain when you put it up, I bet this will show you a list of access points around you.
Sorry about the brain glitch.

Edit: Damm I did it again

hermanningjaldsson · 2011-06-26 18:14:20

iwlist scan:
lo :interface doesnt support scanning
eth0: interface doesnt support scanning
and there came many pages of text, split into cells, apparently. 23 of them.

i guess this is good.

so what would be the next step?

ewaller · 2011-06-26 18:23:15

Next, we have to associate with a wireless access point.

Tell me about the network you would like to join.
Do you have administrative rights on it?
Is it WEP?
Is it WPA? If so can you turn that off for now?
If is WPA and you cannot turn that off, have you installed wpa_supplicant (does pacman -Qs wpa-supplicant show anything?)
Have you installed a wireless manager like wicd or NetworkManager?

hermanningjaldsson · 2011-06-26 18:29:03

Its just a router over here.
i dont know if i have administrative rights, i have the password to it.

how do i find out if its WEP or WPA? it didnt say on the router itself.

and how do i turn WEP and WPA off?

pacman -Qs wpa-supplicant:
gives no reaction.

i dont have wicd or NetworkManager installed.

ewaller · 2011-06-26 18:38:26

Lets go back to the iwlist scan command. Pipe it through less : iwlist scan | less. Look through the output for the cell that has the ESSID of your access point.
Here is mine:

These lines:
Encryption key:on
and
IE: IEEE 802.11i/WPA2 Version 1
Tell me my router is encrypted and is using wpa2.
Look for lines like that in your output, or post the portion of the output (cell) related to your access point

hermanningjaldsson · 2011-06-26 18:52:00

just curious, how do i flush the output to a file?

its cell01 that has my router, it has
ESSID: woaw7.com
it has multiple IE: ... and one of them has, "WPA Version 1".
so i guess that means its WPA.

so i should turn that off, how does that happen?

It also has: Encryption key: on.

You can use the operator '>' which says to take the standard output (as opposed to error output) and send it to the file names to the right.
iwlist scan > scandump.txt
Whereas the '|' operator says to take the standard output and send it to the standard input of the program named to the right. That is what I did with the less command.

I was afraid of that. It does,indeed use WPA encryption. That is good; it is much more secure than is WEP. The bad news is that you must use wpa_supplicant to connect to WPA encrypted routers. You don't have it installed, and we cannot connect with the tools at hand.

Here are some solutions (In rough order of complexity). Let me know which you want to pursue.

1. Find a WEP or Open access point and use it to install the missing tools.
2. Obtain the packages on disk and import them to your system using "Sneaker net" (carrying media across the room and mounting it on your system)
3. Use another computer that can connect to your router to use the router's configuration page to temporarily turn of WEP on the router. (Your system has a wired Ethernet, why can't you plug into the router using a cable? On-the-other-hand, you may not have a browser installed yet)
4. Use a live CD of any Linux distribution that has wpa_supplicant and will associate with your router. establish that connection, then chroot into your Arch installation as the guest and then installing the tools (using the Router connection provided by the host OS)

hermanningjaldsson · 2011-06-26 19:17:56

its seems like i actually do have wpa_supplicant installed.

when i installed i took care to install also, "wireless_tools".

at least i can type wpa_s and then hit tab and it turns to wpa_supplicant
.

ewaller · 2011-06-26 19:24:53

Great.
It has been a long time since I have flown wpa_supplicant by hand. Bear with me as I read https://wiki.archlinux.org/index.php/Wpa_supplicant. I'll be back shortly.

Arch Linux
