rtwn* at pci? port ?
rtwndriver supports PCIe wireless network devices based on the Realtek RTL8188CE chipset.
The RTL8188CE is a highly integrated 802.11n adapter that combines a MAC, a 1T1R capable baseband and an RF in a single chip. It operates in the 2GHz spectrum only.
These are the modes the
rtwn driver can
rtwn driver can be configured to use
Wired Equivalent Privacy (WEP) or Wi-Fi Protected Access (WPA-PSK and
WPA2-PSK). WPA is the current encryption standard for wireless networks. It
is strongly recommended that WEP not be used as the sole mechanism to secure
wireless communication, due to serious weaknesses in it.
A prepackaged version of the firmware can be installed using fw_update(1).
# ifconfig rtwn0 scan
The following hostname.if(5) example configures rtwn0 to join network “mynwid”, using WPA key “mywpakey”, obtaining an IP address using DHCP:
nwid mynwid wpakey mywpakey dhcp
rtwndriver first appeared in OpenBSD 5.8.
rtwndriver was written by Stefan Sperling <email@example.com>. It was based on the urtwn(4) driver written by Damien Bergamini <firstname.lastname@example.org>.
rtwndriver does not support any of the 802.11n capabilities offered by the adapters. Additional work is required in ieee80211(9) before those features can be supported.
