Getting server to boot to terminal by default

Having problems with usb connection dropping every 1 to 2 days for connected weather station, which then requires a reboot to fix.

Looking at running server headless to reduce resources used. To achieve this edit:

/etc/default/grub

put “text” into the line:

GRUB_CMLDLINE_LINUX_DEFAULT="text"

Restart Grub:

sudo update-grub
reboot

udisks automounting is running apparently as part of gnome.. no gnome - no automounting

Fix 1) is to use udisks-glue

sudo apt-get install usbmount udisks udisks-glue
git clone https://gist.github.com/5399914.git udisks-glue  #(or copy and paste if you don't like git)
cd udisks-glue
chmod +x udisks-glue
sudo cp udisks-glue /etc/init.d/.
sudo update-rc.d udisks-glue defaults
wireless connection problems

Having major problems with the wireless connection. Wireless card can be found from command:

lspci | grep Network

Atheros AR9285

has not good reception of signal - 2-3 bars from 5, but problem is that it drops this signal periodically and also has high packet loss.

Followed some instructions at www.xors.me/?p=1069 to install some driver - but I still have problems

Seeing some strange loop for wlan running in syslog

This seems to be running constantly - and presumably crashes out every so often because of some small variation in Wifi signal strength and then has some issues reconnecting.

What is the purpose of this ?
