NM insisted on using the bcm-4318 radio in the lappy even if it was powered down by the switch. It totally ignored a radio in a usb dongle that actually worked where the bcm-4318 never worked for more than 1 minute, even when useing the drivers from xp that came installed to run it. Rebooting to xp disclosed that this pos radio was junk from the gitgo. 2. Getting it setup via dhcp with a usb radio dongle, so I could sit down while out in the shop, and write gcode for one of the 2 machines out there worked flawlessly over an ssh -Y machinename connection, until I wanted to ssh -Y lappy, which is its own name from the house machine. So the dns lookup which NM should have set up, wasn't there, forcing me to string a 25' hunk of cat5 plugged into its ethernet port. Adding its ip address and name to all the hosts files, and fixing all the network related files to be immutable after edited correctly, and then its just one of the family. Strangely, when NM found it couldn't rewrite those files, it made no complaint in any log. And it didn't spin its wheels, burning up the cpu either. 3. I've left it that way in all subsequent installs. Now I remove NM and other than making /etc/resolv.conf a real file, its a 10 minute job after a fresh install to have a working network regardless of which socket I plug its cat5 cable into. With 2, 8 port switches available, soon to be 3 as I'll need another in the garage as I bring a bigger Sheldon 11x36 lathe to life with LinuxCNC. So the end of the cat5 I strung thru the nether regions of the house to get to the garage, will eventually have an 8 port switch on the end of it. That cable was 4 days getting run, a right PITA. I think by now in 2016, if the computer has a working radio, or an ethernet over cat5 port, that it may be able to be made to work by now by people willing to do whats needed, but my long term experience with it has caused me to shoot it on sight. Bug squawks were ignored, or told to buzz off, and fixed versions were way too long working their way thru the pipeline to the users install. Several times I pulled the src and built it here, and it was better but still kept tearing down a working link and trying to find another, so it would eventually go back to the working link, which took it a good 2 minutes to do, then 3 minutes later I'm typing in the dark to /dev/null again. And I still have at least half my hair by using my lambasted by everybody methods. All I can say is that I can carry that lappy to anyplace on my local network, plug it in and boot it up, and the network Just Works(TM). Call me an idiot, and quite a few have, but simpler is better when it just works 100% of the time here. I have no reason to take it to mcd's and use their radio because there I would not have dd-wrt in my router standing guard. Its very very good at that.
