Just got my first Gentoo install up and running and now I want to get wireless working.

When I try to start the wifi interface with
Code:
/etc/init.d/net.wlp7s0 start
it errors with
Code:
* Caching service dependencies ...
* Bringing up interface wlp7s0
* Starting wpa_supplicant on wlp7s0 ...
Successfully initialized wpa_supplicant
wlp7s0: Unsupported driver 'iwlwifi'
* start-stop-daemon: failed to start '/usr/sbin/wpa_supplicant'
* ERROR: net.wlp7s0 failed to start


The wiki lists iwlwifi as the correct driver for my wifi card, "Intel Corporation PRO/Wireless 5100 AGN [Shiloh] Network Connection" (from lspci).

Related lines from /etc/conf.d/net:
Code:
modules_wlp7s0="wpa_supplicant"
wpa_supplicant_wlp7s0="-Diwlwifi"


/etc/wpa_supplicant/wpa_supplicant.conf:
Code:
network={
ssid="Mason Wireless"
psk=(psk here)
scan_ssid=1
}


Anyone know why the driver is not working?

the column to the right of driver says "firmware" my guess is you neglected to

Code:

emerge linux-firmware


as your post doesn't mention firmware.

promythyus,

Code:
wpa_supplicant_wlp7s0="-Dext"
is worth trying too.

I have (for a bit older chip - 4965)

Code:

wpa_supplicant_wlan0="-Dnl80211"


and actually, suprisingly

sys-firmware/iwl5000-ucode

is not masked, so no need for full linux-firmware

I didn't specify in my post but I had installed the firmware for my card.

"-Dext" didn't work but "-Dnl80211" is working, I can ping google at the very least. So thanks dmpogo, how did you work that one out?

It is in my config for the last at least 3 years and my memory faded as of source. Though, I'm pretty sure when I got this laptop in 2008 I have used -Dext for a while and
it was working, but those were the times when this 80211 stack was actively developed in the kernel, adn again, I have an older iwl4965 driver and chipset.

dmpogo,

There are two wireless stacks in the kernel -Dext uses the old one, -Dnl80211 uses the new one.
Which one works depends on your kernel. You may even build both wireless stacks if you want.
