Setting Up WiFi on a New Gentoo Install

patherton · n00b Joined: 08 Jul 2013 Posts: 4

I used Mr. Donahue's SystemrescueCD to install Gentoo, installed wireless-tools, and had selected all wireless drivers in kernel config. I dont see my interface name using ifconfig -a [Only lo and sit0], iwconfig lists lo & sit0 with no wireless extensions.

I am able to modprobe -v rtl8192cu and insert wifi drivers. Still no interface name to wpa_supplicant. What am I missing.

While installing through SystemRescueCD, chroot emerge networkmanager ended up with conflict in PAM use --with-use and --update, had issues --unmaskon-write.

Did emerge --world. Yet the problems persist. I need wpa_supplicant working, need interface for it.

Thanks,
Pete

per debian wiki.... found here http://wiki.debian.org/rtl819x

"Non-free firmware is required for all drivers, which can be provided by installing the firmware-realtek package. RTL8192U firmware is currently not packaged (588142)."

i suspect for gentoo its "emerge linux-firmware" though i could be wrong, and you could be stuck manually digging for firmware.

I had already emerged linux-firmware, had all WiFi modules inserted after boot using modprobe -v rtl8192cu, I followed the above Debian wiki after chrooting through SystemRescuceCD. I see the interfaces after chrooting, since I guess I am using Networkmanager of RescueCD. Unable to see the correct interfaces, upon reboot, I could not emerge NetworkManager because of conflicting installed PAM packages, emerged wicd, Will try networkmaneger tarball from other OS and try.

I just need the interface, also emerged iproute2, no help there either. How do I load all modules automatically during boot.

Thanks.

Once WiFi i set I can proceed with other insrtallatioon

looking at bugzilla.kernel.org for rtl8192cu suggests you might want to try kernel 3.10.1 from the testing branch. Also linux-firmware from the testing branch.
i.e.

echo "sys-kernel/gentoo-sources" >> /etc/portage/package.accept_keywords
echo "sys-kernel/linux-firmware" >> /etc/portage/package.accept_keywords

no need to define version or arch. it actually will update to latest if sync pulls up newer ebuilds. my prism54g device required me inserting firmware manually, and im still thinking thats what the posters going to have to do.

@ 6
specify version and that component eventually goes back to stable, not an unreasonable goal
http://www.gentoo.org/doc/en/handbook/handbook-x86.xml?part=3&chap=3 and http://www.gentoo.org/doc/en/handbook/handbook-amd64.xml?part=3&chap=3 say the default is stable branch
