[SOLVED] hardware issues wireless, bluetooth and webcam

Hi all

I just did my first ever Gentoo install, I managed to get most stuff working, but there are a few things that I need help with. First I can' t get my wireless working, Network Manager isn' t finding any wifi networks, and iwconfig can' t find my wireless adapter, however it can on the live-cd. Second bluedevil keeps saying it can' t find any bluetooth adapters. and thirdly I can' t get my webcam working, any program using a webcam says it can' t find one. below some info on my system:

I know I'm stating the obvious here but be sure to take a look at this article:
http://wiki.gentoo.org/wiki/Wifi

did you enable the appropriate kernel modules?
cfg80211 - wireless configuration API
Generic IEEE 802.11 Networking Stack (mac80211)

and your wireless nic's specific module?
I think it's atheros wireless cards under
device drivers --> network device support --> wireless lan --> atheros wireless cards

as for bluetooth:
http://wiki.gentoo.org/wiki/Bluetooth

did you enable the proper kernel modules?
can you paste the output of lsusb?(assuming that's how your bluetooth's connected)

I don't think I can help with the webcam but here's the wiki page

I seriously doubt you'll get the kernel right on the first compilation, It usually takes a couple of recompilations to get things working.

I cannot access the wiki atm but I though b43 firmware was for the broadcom devices(I'm using broadcom nics and the linux-firmware instead), so I guess you can try out the linux-firmware, there was a support matrix somehwere.

I can't see your bluetooth device, maybe it's connected some other way. if you want bluetooth ASAP you can enable all kernel modules and trim it down later

this is your webcam:
Bus 001 Device 004: ID 04f2:b307 Chicony Electronics Co., Ltd

You can start by looking in the wiki how to configure those chicony webcams

a modprobe not found means that the module was not enabled in the kernel
to enable the module in the kernel go to /usr/src/linux:
#cd /usr/src/linux
#make menuconfig
you will be greeted by the kernel options interface(or whatever it's called)
type / to search for an option(in this case ath9k)
it's found under device drivers --> network device support -> wireless lan -> atheros wireless cards
and press space bar twice (you'll see M next to the option) to build the module under /lib64/modules instead of in the kernel itself

then you want to exit back to your terminal and type
#make modules_install to compile and copy the module to the appropriate location

then try modprobing the module again

Didn't work, I did make modules_install , and rebooted, but it still can' t find the module, I double checked if the module was enabled, and it was. I tried the same for my webcam and bluetooth adapter but same results, did I do something wrong, am I using modprobe wrong?

does it say (M) not (*) next to the atheros wireless cards?

can u list the contents of:
/lib64/modules/3.12.21-gentoo-r1/kernel/drivers/net/wireless

if you can't find this directory, change 3.12.21-gentoo-r1 to your kernel-source's version

/kernel/drivers/net/wireless

Oops, sorry

sorry about that, did not notice, after modularizing the ath9k you have to select your wireless card from the list provided by the ath9k, I can't help you with the exact module, but you can enable all modules and reboot(this way the device manager will load the correct module) and check if things work from there

oke, if I understand correctly I have to go to device drivers --> network device support -> wireless lan -> atheros wireless cards and enable all the stuff in there, but some stuff is not module capable, should I enable it anyway?

Thanks, I did make && make modules_install and make install, and everything is working now, after a reboot wireless networking, bluetooth and my webcam are working fine. Thanks for your help.

if you prefer having just the right module and removing all the other modules you can use #lspci -k to figure out the kernel modules being used by your hardware
