[solved]Wireless, wlan0 can't be wake up...

I followed the wiki to install my wireless..

At first, all the things are going well..

hwdetect --show-net
modprobe iwl4965
lshwd | grep iwl4965
iwconfig

I can see the wlan0 with using iwconfig...

But I can't find wlan0 with using ifconfig....
So I can't bring it up using "ifconfig wlan0 up"..

Why?

Try:

ifconfig wlan0

If no arguments are given, ifconfig displays the status of the currently active interfaces.

You might not even have a wlan0, as wireless devices do not have to be called wlan0.

Often they're just ethX or another name entirely. I''ve set my laptop to use ipw0 (wireless) and rl0 (ethernet).

Re: [solved]Wireless, wlan0 can't be wake up...

ifconfig shows active interfaces only. Use ifconfig -a.

Better still, use man ifconfig.

Re: [solved]Wireless, wlan0 can't be wake up...

when I use ifconfig -a, I can see the wlan0..

But it can't be waken up..

I used "ifconfig wlan0", it can display the information about wlan0..

The problem is whether wlan0 is awake?

If wlan0 is awake, I can scan the wireless, right?  so, I used "iwlist wlan0 scanning", it gave me this error:"err:Network is down"

If I use "ifconfig wlan0 up", it will give me this:"SIOCSIFFLAGS:No such file or directory"

If I use "dhcpcd wlan0", it will give me this:"No such file or directory"

What should I do..... 

My laptop is DELL XPS M1530. I'm sure I had turn the wireless button on..
My hardware is supported, I find the name of my hardware in the wiki: "iwlwifi-4965-ucode for Intel Pro/Wireless 4965 AB/G Mini PCI-E".

Here is the link to the wireless setup page: http://wiki.archlinux.org/index.php/Wir … 000-series

Re: [solved]Wireless, wlan0 can't be wake up...

Now, I find the main problem...
First, I run "

dmesg -c > /dev/null

"
Then, I run "

ifconfig wlan0 up

" it also give me the error: "SIOCSIFFLAGS:No such file or directory"
I run "

dmesg -c

"
I find the important imformation below:
    *  iwl4965: iwlwifi-4965-1.ucode firmware file req failed: Reason -2

I find the explain in Gentoo Linux wiki:
"

This error indicate a firmware version/filename mismatch. Just rename the file to whatever iwlwifi displays in this case: iwlwifi-4965-1.ucode
    If this fails, try an alternate version, perhaps net-wireless/iwl4965-ucode-228.57.1.21.

"
The newest release of iwlwifi is iwlwifi-4965-ucode-228.57.2.21.tgz     07-07-08 00:17:06 ...

I downloaded it, and cp it to my /root with USB Disk [mkdir /mnt/usb, mount -t vfat /dev/sdb1 /mnt/usb, cp]

First, I need to cp the microcode to the FIRMWARE_DIR..
[Based on the instruction of installing Iwlwifi here: http://intellinuxwireless.org/?p=iwlwif … to-iwlwifi

Determine where to install the file.  You can look in the hotplug script '/etc/hotplug/firmware.agent' to determine which directory FIRMWARE_DIR is set to when the script runs.

]

But I can't find the hotplug script... There is not a hotplug directory at /etc ......

I think I will solve the problem soon, I just need a profeessional guide........:D

Re: [solved]Wireless, wlan0 can't be wake up...

The problem is solved by installing the package iwlwifi-4965-ucode.....

I think that problem is that I didn't install the package when I was install Archlinux....
