Default Can I connect to unprotected Wifi?

Hello. I would like to connect to unprotected Wifi. I am aware of risk of this.
My operating system:
Code:
kern.version=OpenBSD 6.1-current (GENERIC.MP) #73: Sat Jul  1 10:53:54 MDT 2017
    deraadt@amd64.openbsd.org:/usr/src/sys/arch/amd64/compile/GENERIC.MP
I have said unprotected. I mean by this lack of WEP/WPA/WPA2, basically anything based on cryptography to authenticate and authorize access. This network restricts access based on MAC addresses, but my MAC is added by admin of this public network. I can connect to this network from the same laptop using Windows operating system, so this is not hardware problem.
I have Wifi network device supported by iwn(4) driver.
Fun thing is that I managed to connect to WPA2-Personal without any problems, but I am stuck at connecting to unprotected Wifi.

I would like to anonymise at least some info, but if you think I censor too much tell me about this.

I see the network existence via command (nwid name is altered, but really contains spaces):
Code:
# ifconfig iwn0 scan
                nwid "word1 space word2" chan 6 bssid 80(censored)e5 -49dBm HT-MCS23 short_preamble,short_slottime
but there are other Wifi networks with the same nwid (they are legitimate, there are several APs to this network).

I have instructed iwn(4) driver to connect to this network by this file:
Code:
# cat /etc/hostname.iwn0                                                       
media autoselect mode 11n
nwid "word1 space word2"
dhcp
This gives me:
Code:
# ifconfig iwn0
iwn0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
	lladdr 00:(censored):cc
	index 2 priority 4 llprio 3
	groups: wlan
	media: IEEE802.11 autoselect (DS1 mode 11g)
	status: no network
	ieee80211: nwid "word1 space word2" chan 6 bssid 80:(censored):e5 -49dB
Some info from Windows when connected to this Wifi network:

Code:
ipconfig /all
