Hi Tim / Kris

Intro:
You may recognize my name as long time forum member and contributor.
I have run against a problem with WiFi where I must be over looking 
something obvious.
I have not run PCBSD on a Laptop but Desktop only in the past few 
versions as I had Dell Laptops with Broadcom Wifi requiring a ndisgen of 
Win Drivers which would periodically Crash..

Problem:
  So.... I now have a Lenovo Thinkpad SL410. which has these NICS
re0 (Realtek 8168) which is my Hardwire and works fine
wlan0 (Intel Pro/Wireless 5100) which is my Wifi and is THE PROBLEM....
  Keep in mind that this is all on a LIVECD as I will not make a Laptop 
install unless I can resolve my WiFi problem.

  WiFi is not found automatically but is discovered once I run the GUI 
System Settings/Configure Network Settings .....
Next I must choose the Device wlan0 Pro/Wireless and Configure it...
I must scan for Wifi Routers which is does and once one is chosen it 
lights up..
I have the FireWall OFF
I have shut off all Security..WEP WAP etc.
..but no ip address is assigned to wlan0 and yet the correct MAC is 
listed in ifconfig.

So of course no connection via Wifi and will not connect nor ping Until 
GUI Network Settings Config

I have read blog.pcbsd.org/2011/02/possible-fix-for-wireless-freezes/
..regarding the conflict between devd and netif startup..
To test this once the wlan0 had been assigned and configured I reran 
route -add my gateway which confirmed that it was already in the list 
and then reran netif script which then connected the wlan0 device to an 
ip address...
I will post the terminal results below from the LIVECD..
Hopefully there is a Workaround so I can install to the Laptop other 
then A hand  config of the Wifi on each Boot and rerunning the netif 
script each time I need a WiFi.
** Take Note the Wifi will ping the Router once configured with the 
Setup both Before and After the netif script is run..but only connect to 
the Internet addresses after the netif script is rerun...***
Thanks for reading.
