Gentoo linux on toshiba sattelite laptop wlan how to?[solved]

roodap · May 9, 2013

i run gentoo linux updated everyday.
my current kernel 3.8.10 with toshiba support module.
my laptop does not find wlan from my new router-modem.
earlier i did not have a wlan modem.
now in the process of installing necessary packages.
i have realtek modules and intel wreless modules in the kernel
what else i need to install
to get wlan conneced?

roodap :

Please post output of "sudo lspci" or "sudo lsusb" depending on if PCI wlan or USB wlan.
Also post output of "sudo ip link show" to see if the interface has been created.

You may just need to download/install the correct firmware for your wlan.

You should find what you need at one or all of the following links:

http://www.gentoo.org/doc/en/handbook/handbook-x86.xml?part=4&chap=4
http://wiki.gentoo.org/wiki/Wifi
http://wiki.gentoo.org/wiki/Wpa_supplicant

And, you'll get far more help in the Gentoo discussion forums: http://forums.gentoo.org/

skittle · May 11, 2013

Ok, this is your wireless chipset:

Code:

02:00.0 Network controller: Realtek Semiconductor Co., Ltd. Device 8723

Firmware for your device is found here:
http://git.kernel.org/cgit/linux/kernel/git/firmware/linux-firmware.git/tree/rtlwifi

Run these commands in gentoo to install the firmware (connect to internet with ethernet)

Code:

git clone git://git.kernel.org/pub/scm/linux/kernel/git/dwmw2/linux-firmware.git
sudo cp -v linux-firmware/rtlwifi/rtl8723* /lib/firmware/rtlwifi/.

Then reboot or load the driver with

Code:

modprobe rtl8723ae

Check if wireless interface is loaded with

Code:

sudo ifconfig

roodap · May 12, 2013

the proceedure you suggested put only rtl8723.bin files. while we need .ko files.
anyways i recompiled my keernel with rtl8723 module
module loads correctly.
still i do not find any wireless access.
i have tried most of the things mentioned in the guides and tutorials
to no avail

ex_bubblehead · May 13, 2013

You need to be much more specific than just "I have tried most of the things mentioned in the guides and tutorials to no avail". What specifically have you tried, and what specifically was the result? The links I gave, if followed, absolutely will get wireless working in Gentoo.

ksham · May 13, 2013

Does ifconfig pick up your wlan interface? If so, can you ifup your wlan interface?

roodap · May 13, 2013

ifconfig gives only the ethernet configuration
iwconfig says sit0 no wireless extension
lo no wireless extension
eth0 no wireless extension

ksham · May 13, 2013

So modprobe didn't pick it up. That means that the driver wasn't properly installed.

I would first try emerge linux-firmware. I'm guessing you should've already tried it but I didn't read the wiki of all the things you could've, would've, should've did.

Seems like Realtek has not posted an official release for the Linux driver, but they provided a Dropbox link to a tarball file: click here. Download it, then `tar -zxf <file>' and cd into it. Then make && make install (as root). Then as root, modprobe rtl8723e. Can you confirm if modprobe picked it up? And `dmesg | grep --ignore-case firmware'

Edit: do you have your kernel source files installed?

ksham · May 13, 2013

Did you try restarting and then check?

roodap · May 13, 2013

yes restarted and no change in the wireless status

ksham · May 13, 2013

Hmm... I don't really know. You can try contacting Realtek directly. They do reply. I've contacted them before about audio drivers.

skittle · May 13, 2013

Can you try

Code:

modinfo rtl8723ae

and see if it is actually loading the correct firmware? it seems like it is not loading firmware.

it seems it is default not on
how or where i configure this driver ?

skittle · May 15, 2013

Well it obviously sees the firmware, and the kernel module loads.
How about try a simply manually loading wlan interface:

Code:

sudo ifconfig wlan0 up

roodap · May 16, 2013

problem is it says wlan0 does not exist.
i have no idea how to make wlan0 device.

skittle · May 16, 2013

OK something is wrong. Check your dmesg output for useful information!

You might want to file a bug report with gentoo.
As far as i know, you have compiled the correct kernel module with kernel 3.8.x and have the correct firmware installed. No good reason wlan0 would not be created

You could try using the rtl8723e driver instead, like in this and other various threads on google:
https://bbs.archlinux.org/viewtopic.php?id=152307

roodap · May 17, 2013

i downloaded the driver rtl_92ce_92se_92de_8723ae_linux_mac80211_0006.0514.2012.tar.gz
but emerge refuses to merge saying no ebuild found
i have not installed packages outside portage before
how can get the driver module rtl8723e from the above package?

ksham · May 17, 2013

What are the contents of the tar.gz?

i have posted this from windows 7
it says compatible to 3.0.2 kernel
there s no .ko files in the rtl8723 e drivers.
there is a makefile which does not run in ech of the driver folders.
unless i can find a ebuild i cannot merge t to kernel.
there is no 3.0.2 kernel sources in te current portage
the latest kernel 3.9.0 also makes rtl8723ae but does not make wlan0 device.

made some progress by copying linx-firmware rtlwifi folder to /lib/linux-firmware/rtlwifi

but still i cannot see any wlan0 working.
what further it needs?

ex_bubblehead · May 18, 2013

Did you emerge and configure wpa_supplicant?

roodap · May 18, 2013

yes i have wpa_supplicant installed. but it does not pick up or i cannot add wireless network with it.
fails to add the ssid and psk

but to my surprise
iwlist scan gives me a lot of nieghbours' wifi modem address including mine.
where ESSID is specified wpa_supplicant looks for SSID
is it normal
somehow i cannot conect to the wifi
