(SOLVED) Adding wlan0

mcduling · 2011-12-18 22:51:44

I am trying to set up my wifi connecton on my HP Pavillion dv4000 and decided to get Arch up and running first before attending to the wireless connection. My system runs fine now and all I need to do to get it to my satisfaction is set up the wireless connection.

I don't have wlan0 at present and can't seem to add it. I have read the documentation as well as Lifehacker's excellent instructions. I don't see wlan0 when i run iwconfig, only lo and eth0. How can I go about addiding wlan0 as the wireless interface?

If you please post the output of ip link and of lspci -nn (That is two n's, not an m)

Please help your readers help you by using

code blocks.

Now, your system has mapped eth1 rather than wlan0 to your wireless. Don't worry, I had the same problem. You can either keep using eth1 as a drop-in name for wlan0, or you can check out the wiki.

The wiki method may seem a little harder at first, but if you plan to use Arch for a long time, it's worth the initial investment.

Thanks for the suggestions, and insights. I have decided to undertake this using the ifrename option. I have installed wireless_tools and run ifrename -i eht1 -n wlan0 but get this reply: Can't open configuration file: No such file or directory.

Sorry, I haven't used ifrename. I just created a couple of simple udev rules. It's really no harder than finding out your cards' MAC addresses using ifconfig, and substituting into the appropriate place in /etc/udev/rules.d/10-network.rules like so

Wiki wrote:

SUBSYSTEM=="net", ATTR{address}=="aa:bb:cc:dd:ee:ff", NAME="lan0"
SUBSYSTEM=="net", ATTR{address}=="ff:ee:dd:cc:bb:aa", NAME="wlan0"

Edit - looking at this again:

mcduling wrote:

That's a typo there, eht1 -> eth1. Does that fix your ifrename problem?

Thanks /dev/zero. Just so I get this correctly, I change the values or words in inverted commas. So "net" becomes something like eth0 and wlan0 and the I leave in ATTR but substitute {address} with mac. Then for the addresses I insert the actual mac addresses for eth0 and in my case eth1 (which will change to wlan0. I only need two addresses, one for eth0 (which is for the ADSL modem cable) and wlan0 (which is for wireless connectivity). Am I on the right track?

This is the exact content in a file called /etc/udev/rules.d/network-devices.rules on my Arch machine:

SUBSYSTEM=="net", ATTRS{address}=="cc:af:78:00:c1:ee", NAME="wlan0"
SUBSYSTEM=="net", ATTRS{address}=="b8:70:f4:b7:08:c9", NAME="eth0"

So, I'm certainly no udev master, but it seems like the general idea goes something like this: we're creating rules for the udev subsystem called "net"; apply any given line when the address attribute matches the given MAC address; the action of the rule is to change the name to the desired device name.

Hope you don't mind me asking: why do you need to change the name of the interface?

Using eth1 will get you connected just as well as using wlan0. I'm using Wicd for wired and wireless connections and all I need to do on machines that use the ipw2200 module (same as yours) is set "Wireless interface: eth1" in Wicd Preferences. If you connect via command line, just use eth1 instead of wlan0. Or am I missing something?

I insist on having different names because otherwise it remains open for the system to randomly rename the interfaces, depending on what gets loaded first. This makes a difference when scripts (or indeed Wicd) expects a particular interface to be the wireless one.

So, since I prefer to force specific names anyway, I'd rather at the same time provide a more meaningful way to distinguish between cards.

samuvuo · 2011-12-19 23:55:32

But of course! Had forgotten all about the race condition of eth*. On laptops that use ipw2200 I tend to add the networking modules in rc.conf (or mkinitcpio.conf) making sure ipw2200 loads first and that takes care of the problem.

Edit: the above makes no sense. What I meant was: I load Ethernet controller's module first (gets eth0) and then wireless (eth1). When I control the loading order, there's no more interface name swaps.

Thanks for the assistance. I have added the network.devices.rules and used my mac addresses. All seemed to go fine. I then ran iwconfig and didn't see wlan0.
This is what I received: (Not sure how to code block, so sorry for this)

It is easy.... I went ahead and did it for you. Use the edit link on the post to see what I did.

Also, see The BBCode link below where you post

mcduling · 2011-12-20 02:36:38

I have just gone into /etc/rc.conf to change the notation for eth0 and wlan0. I will essentially add wlan0 here but do I use the same values for address, net mask, broadcast and gateway for both of them? Or do they have unique values? If unique, where do I find the values for wlan0?

What does iwlist scan say?

BTW: My other requests were overcome by events. The thread moved past the point where they were relevant, so I had nothing to add

Do you know the ESSID of the router to which you are trying to associate?
Do you know if it is open, WEP, WPA or WPA2 ?
If it WEP, do you know the key?

I want to try to associate by hand using iwconfig from the command line.

mcduling · 2011-12-20 08:17:31

Yes, I do know them. I have a WPA2 set up on my network.

I presume when entering the name of my ESSID, if it has more than one word in its name, like The Network, I enter it thus: The_Network.

Am I on the right track?
