--=_731c374e67632721ee1a872abb52d6ae Content-Transfer-Encoding: 7bit Content-Type: text/plain; charset=UTF-8 Dear Polytropon, Good morning. Many thanks for your thorough response to my questions. The complete name of the circuit board is as follows: "TP-Link TL-WDN4800 450 Mbps Wireless N Dual Band PCI Express Adapter." In my previous message, I mis-identified the manufacturer, as you correctly noted. To the command "pciconf -lv," I received the following response: none0@pci0:40:0:0 class=0x028000 card=0x3112168c chip=0x0030168c rev=0x01 hdr=0x00 vendor = 'Atheros Communications Inc.' device = 'AR9300 Wireless LAN adaptor' class = network Upon checking the webpage specified in your message, I read the following line: "The ath(4) driver supports all Atheros Cardbus and PCI cards, except those that are based on the AR5005VL chipset." The three modified files are /etc/wpa_supplicant.conf, and /etc/rc.conf, and /boot/loader.conf. Copies of these files are attached.

I am attempting to install a wireless network interface circuit on a computer running FreeBSD 9.1. I have read the very thorough instructions written by Messrs.
