Comment 1 Tony Narlock 2015-09-14 19:24:59 UTC 
Hi, I am finding conflicting information. Another issue mentions rtl8188ce (https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=168860).

Is anyone here running rtl8188ce correctly? The issue above didn't give us an svn version, so far my research hasn't found anyone successfully running this.

I do see "rtl8188ce-vau" mentioned in the top of https://github.com/freebsd/freebsd/blob/master/sys/dev/usb/wlan/if_urtwn.c.

Are there potentially multiple versions of rtl8188ce? Anymore information I could provide?

It's been my understanding for a while rtl8188ce support doesn't exist, or is missing.

I have another issue at https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=203105 to port the OpenBSD rtwn driver (new in 5.8) which I had good results with.

Looking for a word back on this and we'll handle things accordingly.

If by chance I'm totally out of the loop - no problem, we'll at least been on the record / more clear on the state of it.

As an update:

> That's it. Unfortunately, the only OpenBSD driver that has support for this is the RTL8188CE-VAU, a USB variant chipset, via the urtwn(4) driver. which is USB-only. There is no driver for the for the PCI-bus RTL8188CE.

So we are in fact missing support for RTL8188CE (the PCI one) you would find in a laptop like the Thinkpad X230.

Seems to be fixed in r293010.
