Adventures with Wireless for NetBSD
====================================

Notes 
------ 

My `/etc/rc.conf` file has the following:

.. code-block:: bash

   dhcpcd=YES
   dhcpcd_flags="-qM wm0 iwn0"

However, I find this from dhcpcd man page concerning the `-M` flag:

        Multiple interfaces
             If a list of interfaces are given on the command line, then dhcpcd only
             works with those interfaces, otherwise dhcpcd discovers available
             Ethernet interfaces that can be configured.  When dhcpcd is not limited
             to one interface on the command line, it is running in Manager mode.  The
             dhcpcd-ui project expects dhcpcd to be running this way.

             If a single interface is given then dhcpcd only works for that interface
             and runs as a separate instance to other dhcpcd processes.  The -w,
             --waitip option is enabled in this instance to maintain compatibility
             with older versions.  Using a single interface, optionally further
             limited to an address protocol, also affects the -k, -N, -n and -x
             options, where the same interface and any address protocol will need to
             be specified, as a lack of an interface will imply Manager mode which
             this is not.  To force starting in Manager mode with only one interface,
             the -M, --manager option can be used.

I will comment out `dhcpcd_flags` to see if that allows `iwn0` to get an IP address. If that fails, I will set `dhcpcd_flags` with only `iwn0`.

Commenting out `dhcpcd_flags` seems to work. I unplugged my ethernet cable from `wm0` and rebooted. When NetBSD fully booted, my wireless NIC had an IP address!. Before, the only way I could get an IP address was to have the ethernet cable plugged into `wm0`.

My Working Setup
----------------- 

`/etc/rc.conf`

.. code-block:: bash

        sshd=YES
        ntpd=YES
        ntpdate=YES
        hostname=netwriter.ronverbs.dev
        # Network
        ifconfig_iwn0="up"
        wpa_supplicant=YES
        wpa_supplicant_flags="-i iwn0 -c /etc/wpa_supplicant.conf"
        dhcpcd=YES
        # dhcpcd_flags="-qM wm0 iwn0"
        # ----------

`/etc/wpa_supplicant.conf`

.. code-block:: bash

        ctrl_interface=/var/run/wpa_supplicant
        ctrl_interface_group=wheel
        update_config=1
        network={
                ssid="Brentwood Guest"
                psk=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
                scan_ssid=1
        }
        network={
                ssid="Brentwood"
                psk=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
                scan_ssid=10
        }

Now, rebooting still allows me access to the web via wireless.

Another Note about wpa_supplicant:
---------------------------------- 

I was getting the following when trying to connect, but once I removed the `dhcpcd_flags` line from `/etc/rc.conf`, that went away.

.. code-block:: bash

        Starting wpa_supplicant.
        Successfully initialized wpa_supplicant
        ioctl[SIOCS80211, op=20, val=0, arg_len=7]: Invalid argument
        ioctl[SIOCS80211, op=20, val=0, arg_len=7]: Invalid argument
