Wifi works in Mint, not in Arch and I am STUCK. Heeelp!!

Reploid · 2008-05-09 17:47:30

I am stuck and I need help.

I don't really understand it, it should be pretty straighforward, even for a total n00b like me. I have a standard Intel Corporation PRO/Wireless 3945ABG Network Connection (rev 02), which is pretty common these days. I dual boot with linux mint, and wifi is OK in Mint.

I have read the wiki on netcfg2, the beginner's guide, and the wireless wiki.

I can scan by using iwlist scan, so the driver should be fine.

After copying the wpa.example file and filling in my password, the netcfg give the output: (my network is called lol, I have such a hard time with wifi in linux, it is to laugh at )

[root@archcomputer reploid]# netcfg2 lol.example
:: lol.example up                                                        [DONE] 
[root@archcomputer reploid]#

I should be able to browse the web using my wireless interface, but I can't.

The whole output from ifconfig, lsmod, netcfg2, etc is here: http://pastebin.com/me8548a4

I don't even have a clue anymore what I should look for. Can anybody give me a hint before I see if I can get it working by installing network-manager?

This is what I have done to get it working.
I have to created (getting hits using the example file) a config file for my connection and put it in /etc/network.d/ (I called it "home").
Then added "net-profiles" to the DAEMONS array in /etc/rc.conf and I added the name of the config file in /etc/network.d (home) to the NETWORKS array.

Try that, reboot and see if works.

Will try. Is the .examples extension necessary?

Are there anything else I need to type in the rc.conf file beside "net-profiles" under DAEMONS, and the name lol.examples in NETWORKS?

Do I need to list wlan0 next to eth0? This is how it looks like in my file now.

# Wireless: See network profiles below
#
#eth0="eth0 192.168.0.2 netmask 255.255.255.0 broadcast 192.168.0.255"
eth0="dhcp"
INTERFACES=(eth0)

Oh, and do I need to comment out the NETWORKS word?

Here is mine:

eth0="eth0 192.168.0.2 netmask 255.255.255.0 broadcast 192.168.0.255"
INTERFACES=(!eth0)

(I don't need eth0 but maybe you do)

NETWORKS=(hwl)

cat /etc/network.d/hwl

CONNECTION="wireless"
INTERFACE=wlan0
SCAN="yes"
SECURITY="wpa"
ESSID="stayout"
KEY="yeah"
IP="dhcp"
TIMEOUT=20

Verify pacman -Qi iwlwifi-3945-ucode
Check if your ip is valid (assigned by dhcp?) and try to ping a valid ip.

The .example extension is not needed (it's there on the example file to indicate it is an example file )

Under DAEMONS you usually put what you want to be run as a daemon at startup.

If you use wireless only, leave INTERFACES empty, i.e. INTERFACES=() and comment eth0="dhcp" on the previous line. You will activate wlan0 through the net-profiles (as the comment says "Wireless: See network profiles below").

As for NETWORKS, yes, you need to comment it out, otherwise it won't be processed.

EDIT: sorry I'm getting confused now. Comment out = removing the # right? I'm spending too much time in this bloody library

Reploid · 2008-05-09 18:30:48

Verify pacman -Qi iwlwifi-3945-ucode

Explicitly installed. Version 2.14.1.5-2

I don't really understand the adding of the word net-profiles in the daemons section; pacman -Q doesn't return any net-profiles package on my system and pacman -Ss doesn't return any net-profiles package. So what is net-profiles? There is no man entry for netcfg2...

And just for understanding purpose; what is the purpose of putting any profiles in the rc.conf file if I want to swap between networks at will? Can i do that using netcfg, or do I need another manager for that?

EDIT: sorry I'm getting confused now. Comment out = removing the # right? I'm spending too much time in this bloody library

Yeah, removing the #

And please don't give me a bad conscience for not studying in the library.

If you use wireless only, leave INTERFACES empty, i.e. INTERFACES=() and comment eth0="dhcp" on the previous line. You will activate wlan0 through the net-profiles (as the comment says "Wireless: See network profiles below").

If I want to be able to use both, should I put a # in front of the eth0=dhcp and make a profile for ethernet for netcfg2 to read, just like the wireless profile, and list it under NETWORKS?

If you want to use eth0, just leave eth="dhcp" uncommented and INTERFACES=(eth0). You need net-profiles for wireless only.

As for net-profiles, that is part of netcfg2, so it's not a package on its own.
I am not so sure about swapping networks with netcfg2, since I only use one regularly. If you want a GUI to do that, I suggest you to use Wicd. Or wait for a more educated user in this matter

Don't worry for me, I'm studying hard, spending my days in here

Reploid · 2008-05-09 19:08:53

Up and running!!!!

You need net-profiles for wireless only.

Strangely, however, there are .examples files for ethernet configuration as well. I tried to use that combination file in my NETWORKS (), but it didn't work out.

As for net-profiles, that is part of netcfg2, so it's not a package on its own.

I see. Didn't say anywhere, but I should have known.

Do you know of a way to swap back and forth between wireless and eth0 without having to reboot?

And last but not least

Thank you guys, I would not have managed this without help.

finferflu · 2008-05-09 19:24:19

Try with (as root):

/etc/rc.d/network restart

moljac024 · 2008-05-09 22:58:46

Or you could use networkmanager instead.....that's what I use for my laptop, it's much easier, you have a tray icon and you can just click click clickady click

I know it's present in fedora and Ubuntu, so Mint (being an Ubuntu spin-off) probably uses it too, so chances are you are already familiar with it.

Set up a profile for your wired and wireless connection, each representing the configuration necessary for the interfaces, then ...

#netcfg2 wired_connection
#netcfg2 wireless_connection
