Hello,
I wanted to connect my openbsd system to wifi. So I downloaded and installed the the necessary wifi firmware using wired connetion. As stated in openbsd wireless networking faq I edited the /etc/hostname.mtw0 file and added the necessary details according to the format. Then I started the /etc/netstart and ifconfig showed the status to be active. But I had no internet connection. I tried using dhcp via ifconfig mtw0 inet autoconf and tried dhclient but noone work there was no ip in netstat -rn.
