My Intel(R) Wifi Link 5100 AGN - not detected
 
Hi Mates,

I'm having problem on installing the right driver for my WiFi card (Intel Wifi Link 5100 AGN). Can someone help me out on how will my Linux OS 2.6.21-1.3194.fc7 be able to detect my WiFi card in my laptop. Hope that it will be a step-by-step because I'm really a newbie on Linux and I just installed Linux OS as dual both on my Vista laptop.

Thanks in advance guys. :)

I have the same card and it works perfectly on
my slackware 12.2.

0. Are you sure it's not detected? What does

dmesg | grep -i wireless

display?
And this one:

cat /proc/net/wireless

If the results above are negative:

1. first
Check that you have a kernel with the right configs:

zcat /proc/config.gz | grep IWL

it should display something like:

CONFIG_IWLWIFI=m
CONFIG_IWLCORE=m
# CONFIG_IWLWIFI_LEDS is not set
# CONFIG_IWLWIFI_RFKILL is not set
# CONFIG_IWLWIFI_DEBUG is not set
CONFIG_IWLAGN=m
# CONFIG_IWLAGN_SPECTRUM_MEASUREMENT is not set
# CONFIG_IWLAGN_LEDS is not set
# CONFIG_IWL4965 is not set
CONFIG_IWL5000=y
# CONFIG_IWL3945 is not set

if the kernel wasn't built with the uncommented lines
(CONFIG_IWLWIFI=m, etc) then you'll need to rebuild the
kernel with at least these 4 uncommented lines

2. second
check that you have the firmware for that card installed
on my slackware box the firmware is installed in /lib/firmware
and here's what I get when I do a

ls /lib/firmware/*.ucode

/lib/firmware/iwlwifi-3945-1.ucode /lib/firmware/iwlwifi-4965-2.ucode
/lib/firmware/iwlwifi-3945-2.ucode /lib/firmware/iwlwifi-5000-1.ucode
/lib/firmware/iwlwifi-4965-1.ucode

The firmware for that card is iwlwifi-5000-1.ucode

Your distribution should have installed it normally.

Hi Vonbiber,

Thanks for your quick reply. Please find below results:

[Ohmeng-Amplex@localhost ~]$ su
Password:

[root@localhost Ohmeng-Amplex]# dmesg | grep -i wireless

[root@localhost Ohmeng-Amplex]# cat /proc/net/wireless
Inter-| sta-| Quality | Discarded packets
| Missed | WE
face | tus | link level noise | nwid crypt frag retry misc | beacon | 22

[root@localhost Ohmeng-Amplex]# zcat /proc/config.gz | grep IWL
gzip: /proc/config.gz: No such file or directory

[root@localhost Ohmeng-Amplex]# ls /lib/firmware/*.ucode
/lib/firmware/iwlwifi-3945.ucode /lib/firmware/iwlwifi-5000-2.ucode
/lib/firmware/iwlwifi-5000-1.ucode

I actually tried last time copying the file "iwlwifi-5000-1.ucode" to my /lib/firmware library which I just downloaded from Intel site. (Reason why it is appearing on the list of .ucode files)

The readme file is so advanced to me which I can't follow yet as a newbie for it says something about kernel edit.

Do you have any other suggestion.

Thank you.

Hi All,

Any more suggestions mates?

Thank you. :)

ok, so you already have the driver
check the size and compare it with mine (to make sure it's not corrupted)

ls -l /lib/firmware/iwlwifi-5000-1.ucode
-rw-r--r-- 1 root root 345008 2008-06-02 18:37 /lib/firmware/iwlwifi-5000-1.ucode

You probably don't have the right configs for your kernel
If you don't have these in your kernel config file

CONFIG_IWLWIFI=m
CONFIG_IWLCORE=m
CONFIG_IWLAGN=m
CONFIG_IWL5000=y

you'll need to rebuild it by enabling these config options

could you run this:

zcat /proc/config.gz | grep IWL

and paste the result here

Don't know if this will help anyone, bit my Intel wireless 5100 uses the iwlagn module which is what Intel recommends.
