Hi,

I've used Gentoo in the past on this laptop and iwlwifi worked just fine. It also works with an Ubuntu livecd, but for some reason is not working now. When it used to work, lspci -k would show iwlwifi as a driver loaded for my card.

iwlwifi is compiled into the kernel, but when I type lspci -k, it is not loaded as a driver. Also, when I type iwconfig, I see wlan0 & wlan1 - I only have one wireless card! I do not understand why there are now two.

When I try iwlist wlan0 scan or iwlist wlan1 scan, I get no results. wpa_supplicant can't connect to any networks, nor can network manager in KDE. I am stumped.

Here is the output of emerge --info

try installing the firmware (ebuild linux-firmware installs ALL available firmware).
if it still does not work then, you might have to install rfkill to (un)block the wifi-devices or use iw instead of iwconfig (on my old notebook iwconfig stopped working some kernel-versions ago, but iw works).
also i think it is recommended to install all wifi-drivers as modules.
GOOD LUCK!

I emerged linux-firmware and iwlwifi works! Huzzah!

However, I get this when I run wpa_gui, from /var/log/messages. It scans, it sees the network, but never connects.

I have a dangerous question. I'd like to simply have a widget that sees a list of networks, that I can choose. Once I choose, it asks me for a password, and it just connects.. no telling it what type of network, what type of encryption, or editing a conf file more than once. Like what shows up in Ubuntu or Mint when you boot into the OS. Is there some tool you can point me in the direction of that allows this? I take my laptop to many different places, I cringe at the idea of going through menus or editing conf files just to connect to someone else's wifi.

Thank you!

Apparently I had networkmanager still installed. I removed it and all is well.

I still connect to networks based on what is in /etc/conf.d/net

Code:

hostname="thinkpad"
modules="wpa_supplicant"
modules="dhcpcd"
trl_interface="/var/run/wpa_supplicant"
config_wlp3s0="dhcp"


and my /etc/wpa_supplicant/wpa_supplicant.conf

Code:
ctrl_interface=/var/run/wpa_supplicant
update_config=1

network={
        ssid="mywifinetwork"
        psk="mywifipassword"
        proto=WPA
        key_mgmt=WPA-PSK
        pairwise=TKIP
        group=TKIP WEP104 WEP40
        auth_alg=OPEN
}


But it'd be great to have some simple all in one kinda widget on the taskbar with a list of networks that just lists networks I can connect to.

The problem here is that when I run wpa_gui, all it sees is wlan0 - which is not real! wlp3s0 is my interface, I do not know where wlan0 was found. If I iwlist wlan0 scan, I find nothing, which is how I know it is not linked to a real hardware device. I have to ps xa | grep wlp3s0, kill every process, then /etc/init.d/wlp3s0 start, then run wpa_gui in order to use it to manage wireless networks, which is inconvenient if I am out & about.

simple all in one kinda widget on the taskbar with a list of networks that just lists networks I can connect to.

sorry, can't help you there - i rarely us GUIs. (but there must be sth.)

maybe there is an old udev-rule that creates wlan0 (check in /etc/udev/rules.d/)
if you want stick with the "old" ifnames (i prefer wlan0 and eth0) you can boot with the kernel parameter
Code:
net.ifnames=0

GOOD LUCK!

Have you tried compiling it as a module? I actually had similar problems building it in to the kernel.

I prefer the old rules. The only good reason for having enp0s25 instead of eth0 is to utilize the memory muscle lost when speed dial & phones with address books built in took over in the late 90s. ;) What changed? Why are names now so long?

I used Linux in 2002-2003, 2006-2009 as a server, and not again until a few months ago, so there is a four year knowledge gap.

I'll try compiling it in as a module and see what occurs. It's strange, even if I unmerge networkmanager, it is reemerged & causes problems when I emerge -av world. If anyone is having problems where wpa_gui or wpa_supplicant can't connect to wi-fi networks after emerging world, check if networkmanager has recompiled itself! Drove me nuts because I didn't check, since I thought I already uninstalled it.

I'll be on the hunt for a "real" GUI besides wpa_gui next. Thanks again for all the help.
