Automatic reconnection when wireless connection drops? wireless script?

[jonathonp]

The wireless connection we have at work drops out on a number of occasions throughout the day and thus requires me to reactivate via:

System>Administration>Network

I find the whole thing time consuming and annoying.

Could i create a shell script with user privileges whereby i would just click on a link to reconnect/ repair my connection and also for automatic connection when it drops. This would be really useful.

This is how i set up my rt73 usb adapter in which i compile myself from http://rt2x00.serialmonkey.com/wiki/index.php/Downloads

gedit /etc/sysconfig/network-scripts/ifcfg-wlan0

# rt73
DEVICE=wlan0
BOOTPROTO=dhcp
HWADDR=00:0E:2E:CE:72:D1
ONBOOT=yes
TYPE=wireless

Also another question that has been bugging me for a long time is how to connect using dhcp in the terminal. For a static address i use the following:

su -
modprobe rt73
ifconfig wlan0 up
iwlist wlan0 scan
iwconfig wlan0 ap any
ifconfig wlan0 192.168.1.102 netmask 255.255.255.0
echo nameserver 192.168.1.1 > /etc/resolv.conf
echo nameserver 203.121.130.39 >> /etc/resolv.conf
echo nameserver 203.144.255.72 >> /etc/resolv.conf
route add default gw 192.168.1.1
ifconfig -a

Which version are you running?
Have you tried Network Manager?
It will do the dirty work for you once you associate with the AP it will try to reconnect if it disconnects or some reason.
Is the system being left alone, a server, ... is that the reason for the use of scripts?
