Re: wpa-supplicant service configuration. Guile is hard

Hello! I have several questions about wpa-supplicant + dhcpcd  services.

First of all I do not want to use networkmanager and I usually get Internet working manually with this:
# cat startnet
#!/bin/sh
#connect to wi-fi through wpa_supplicant
herd stop wpa-supplicant
rfkill unblock wifi
wpa_supplicant -B -i wlp2s0 -c /etc/wpa_supplicant/wpa_supplicant.conf
sleep 2
dhclient -v wlp2s0
#./startnet

I configured services wpa-supplicant and dhcpcd in my config.scm (in attach). Guix reconfigures my system normally, start services wpa-supplicant, networking, dhcpv4-daemon. But these services do not give me Internet. `ping gnu.org` says unknow host.

The wpa_supplicant.conf is the same as I use. But dhcpcd.conf is that from one forum.
I really do not know what to write there. ip of my router is 192.168.1.1 but the other lines are from forum.
Please, let me see how configure dhcpcd if usually I used `dhclient -v wlp2s0`.
What to type there?
Also is it ok my wpa-supplicant-service-type config?
And why I have NetworkManager in my /var/log/messages, is networkmanager living in my system? How to push it out?
