Hi Nickolas, The GENERIC kernel won't attach this device to rtwn(4) yet. rtwn(4) will only attach to 8188ce cards. That's why the 8192ce shows up as "not configured". You'll need a self-compiled kernel to try this driver with your device. To learn about doing this I recommend you start reading here: http://www.openbsd.org/faq/faq5.html#Bld all the way up to (and including) this section: http://www.openbsd.org/faq/faq5.html#BldKernel Your goal is to have a self-built -current GENERIC kernel which includes the patch below. Once you've got the -current sources (see the FAQ for how to get them) run the commands below before building the kernel. Please save this email as a text file (say, in /tmp/patch.txt) and use it as input for the patch program: cd /usr/src/sys/dev/pci patch < /tmp/patch.txt Now proceed with the kernel build steps and reboot into your new kernel. The device might now work. Or it might not. In either case, please report back. Thanks! The patch follows below. It adds one line to the file if_rtwn.c which associates the 8192ce device with the rtwn(4) driver.
