There may be other unforeseen breakage primarily in the handbook portion of the wiki.
The Table Of Contents section of each "PC-BSD® Users Handbook" page may be the best workaround.
Wireless Devices Known to Work
Table 1 provides a handy resource for checking to see if your wireless driver is known to work on FreeBSD and PC-BSD. If a driver that you are using is not listed, please create a wiki account and add it. Devices should be added alphabetically (then numerically).
If you are unsure of the name of your wireless device, check the output of this command: pciconf -lv | grep -i wireless. If it is a USB device, use usbconfig instead.
If your wireless device does not work, take a look at the tables on the Wireless Testing page.
