Why do you do this all manually instead of using
wpa-supplicant-service-type and dhcp-client-service-type?

Your configuration looks … adventurous.  Here are some recommendations:

* don’t nest modify-services.  Nothing good will come of this.  It only
  serves to confuse you.  “modify-services” can modify more than one
  service at once.

* don’t leave parentheses on lines all by themselves.  They get lonely.

* don’t use dhcpd-service-type unless you want to run a DHCP server.
  Use dhcp-client-service-type for the DHCP *client*.

* you don’t need to add wpa-supplicant to the list of globally installed
  packages.  The service is enough.

* maybe try fixing the indentation (Emacs can do this with M-q) — it’s
  very hard to understand the configuration when the indentation tries
  hard to mislead you.
