systemd-network wireless setup

[bittwister]

Trying to get wireless nic to work under systemd-network.service.
System has two fixed ip wired nics and wireless.
Moving wired nics under systemd-network has decreased boot time by ~40 seconds.

I want my wireless to connect to one of 4 modems by default. From what I misunderstand I should be able to link /etc/wpa_supplicant.conf to whichever /etc/wpa_supplicant/MODEM.conf and next reboot/network restart should have an established connection. So far have failed to bring up the wireless connection connected to modem.
route -n shows it there but can not ping yahoo.com if I drop the wired connection. Current settings:

Code: Select all

# cd /usr/lib/systemd/network/
# ls -1 *_my__*
10_my__enp3s0.network
11_my__enp4s0.network
12_my__wlp2s0.network

# grep -v ^# 10_my__enp3s0.network

[Match]
Name=enp3s0

[Network]
Description=LAN_NIC

[Match]

For above to work

systemctl mask network.service
systemctl mask network-up.service
systemctl mask NetworkManager.service
systemctl mask NetworkManager-wait-online.service

ln -sf /run/systemd/resolve/resolv.conf /etc/resolv.conf
systemctl enable  systemd-resolved
systemctl enable systemd-networkd
systemctl enable systemd-networkd-wait-online
reboot

Trying to get wireless nic to work under systemd-network.service.

May I ask why? Why not simply use networkmanager?

[bittwister]

I have pretty much have automated my clean install scripts.No network managers required.
Only reason I need an outbound wireless connection is so I can borrow my neighbor's connection to use my VOIP phone to call tech support if I lose internet.

Solution was to create /etc/wpa_supplicant/ to hold my $MODEM.conf files.
Modify INTERFACES="" in /etc/sysconfig/wpa_supplicant to have my wireless interface device.
create a desired.conf in /etc/wpa_supplicant/
soft link /etc/wpa_supplicant.conf to /etc/wpa_supplicant/desired.conf.
start wpa_supplicant and run wpa_gui, to create/save the desired.conf file.

Most modems are setup as dhcpd servers to hand out dynamic ip addresses.
I like to setup my network with static ip addresses and so far any modem I have used allows me to pick an ip address.
You can use ifconfig -a to get your wireless device and its bssid value.
ssid and psk are from your router wireless settings.
If you have SSID broadcast disabled, I suggest enabling it until you get wap_gui to save your settings.

With all the above in mind, here is what I did.

Code: Select all

systemctl stop wpa_supplicant
mkdir -p  /etc/wpa_supplicant/
chmod 600 /etc/wpa_supplicant/

cp  /etc/wpa_supplicant.conf /etc/wpa_supplicant/wpa_supplicant.conf_vinstall

ifconfig -a
  snippet of interest
wlp2s0: snip
        snip
        ether 70:f1:a1:e9:e0:a8
Using the above,

kwrite /etc/sysconfig/wpa_supplicant
and set     INTERFACES="-i wlp2s0"
save/quit

cd /etc/wpa_supplicant/
cat > fios.conf
ctrl_interface=DIR=/run/wpa_supplicant GROUP=wheel
update_config=1
network={
        ssid="my_fios"
        bssid=18:1b:eb:fb:89:8d
        psk="snip e6dd6228a69 snip"
        scan_ssid=1
}
^d          #<=====   That is a Ctrl+d

ln -sf to /etc/wpa_supplicant/fios.conf /etc/wpa_supplicant.conf

and created /usr/lib/systemd/network/12_my__wlp2s0.network with

[Match]
Name=wlp2s0

[Network]
Description=WIFI
DNS=127.0.0.1

[Address]
Address=192.168.1.6/24

[Route]
Gateway=192.168.1.1
Metric=30


systemctl start wpa_supplicant
systemctl status wpa_supplicant

wpa_gui &



At this point you would click scan to see your router and use Manage Networks click Edit to set desired value and click SAVE.
If Current Status has SSID: BSSID: filled in, you have logged into the router. If not, keep playing with Manage Networks EDIT.

Note: if you have set your router it not broadcast SSID then add scan_ssid=1 in network section and remember to go back and disable it in the modem.
