 Posted: Thu Jan 15, 2015 5:53 am Post subject: Newbie trying to get Intel 2915ABG up via ipw2200 module |
 |
|
New Gentoo user here.
I successfully installed Gentoo using The Gentoo Handbook on an old CF18 Panasonic Toughbook I had laying around to gain some Gentoo experience using the genkernel.
I later successfully got an x server up and running and later XFCE.
Next step is to get wireless up and running.
lspci shows this particular laptop has an Intel Corporation PRO/Wireless 2915ABG card in it which requires the IPW2200 kernel module.
I eventually found the option in menuconfig by following guidance from this post.
I also emerged ipw2200-firmware
I then recompiled my kernel by doing:
| Code: |
cd /usr/src/linux
make modules_prepare
make
make modules_install
make install
grub2-install /dev/sda
grub2-mkconfig -o /boot/grub/grub.cfg
reboot
|
Upon reboot modprobe shows:
| Code: |
CF18_Gentoo ~ # modprobe ipw200
modprobe: FATAL: Module ipw200 not found.
|
ifconfig shows lo and my ethernet.
dmesg | grep ipw2200 shows nothing.
Any advice for a newbie on how to get this up? |

Make sure you have configured it as a module.

Did you happen to forget to mount /boot before doing so?
BTW: Once grub is installed, another grub2-install on rebuilding the kernel is not needed.

Try grepping domain, port and slot number as received from lspci | Quote: | $ /usr/sbin/lspci -k

IPW2200 is configured as a module.
/boot was mounted when I updated the grub2 config via grub2-mkconfig -o /boot/grub/grub.cfg
| Code: | lspci -k
01:03.0 Network controller: Intel Corporation PRO/Wireless 2915ABG [Calexico2] Network Connection (rev 05)
Subsystem: Intel Corporation Device 1000
Kernel modules: ipw2200
...
CF18_Gentoo linux # dmesg | grep 01:03.0
CF18_Gentoo linux #
|
and unfortunately searching domain, port, and slot number didn't yield any results (thanks for illustrating the -k option)
Any other ideas? |

I'm not entirely sure but I guess some other kernel option maybe needed for getting the Kernel driver in use: line. Or maybe the interaction of firmware with kernel module.
Maybe you have to put something in /etc/conf.d/modules | Quote: | $ grep -v ^# /etc/conf.d/modules
modules_2_6="${modules_2_6} iwl3945"
module_iwl3945_args_2_6="" |
Just compare to my lsmod, there I have iwl3945, iwlegacy, mac80211 and cfg80211. | Code: | $ lsmod

Still no luck.
Is this error in dmesg a problem?
| Code: | [ 987.957216] cfg80211: disagrees about version of symbol wireless_send_event
[ 987.957223] cfg80211: Unknown symbol wireless_send_event (err -22)

Thanks! |
