You do not need the lo interface mentioned in the script.

Here are some suggestion you may want to try, just be warned that I haven't actually tried any of these suggestions.

1. Put a sleep 20 statement at the top of the script -- see if something changes at boot.

2. What about changing or putting these changes in the /etc/network/interfaces script? In fact what are the contents of your /etc/network/interfaces file?

[cmichaelt]

contents of /etc/network/interfaces

auto lo
iface lo inet loopback

will test the second suggestion as i've already tried the first with sleep 40 and nothing came of it, will have to wait for a couple hours though. have class.

tried adding the changes to /etc/network/interfaces and commented out the changes in /etc/rc.local but nothing happened at all this time.

when i use the /etc/rc.local script then login. i have to do these commands to get a wireless connection to the router:

sudo ifconfig wlan0 down
sudo iwconfig wlan0 essid "bahay"
sudo ifconfig wlan0 up

then this to get connected to the world wide web.

sudo route add default gw 192.168.1.1

Can you post your new "interfaces" file? Thanks. Strange indeed!

[cmichaelt]

contents of /etc/network/interfaces

auto lo
iface lo inet loopback

ifconfig eth0 down
ifconfig wlan0 down
ifconfig wlan0 192.168.1.108 netmask 255.255.255.0
iwconfig wlan0 essid "bahay"
ifconfig wlan0 up
route add default gw 192.168.1.1

Wouldn't it be more appropriate similar to this structure or syntax?

auto wlan0
iface wlan0 inet static
address 192.168.168.40
gateway 192.168.168.230
dns-nameservers 192.168.168.230
netmask 255.255.255.0

you sir are a genius, thank you for your help!

Just upgraded from Gutsy to Hardy. Using a Belkin F5D7050 v3002, the RT73 chipset. Under Gutsy, it didn't work out of the box, I was using the compiled Ralink driver and that worked, but wouldn't support WPA (though WPA worked under Windows). After I upgraded to Hardy (not a clean install), that RT73 driver is no longer listed under Restricted Drivers Manager like it was in Gutsy and "sudo modprobe -l |grep rt73" only returns the rt73usb.ko listing, so it looks like Hardy supports my adapter out of the box (awesome! is this correct?)

I still can't get WPA to work; I was hoping this would change if the built-in drivers are working under Hardy. I tried the simple way, entering my passkey under System-Administration-Network, but that won't connect. So I tried the instructions in this thread under "WPA with Ra Based chipsets" but on each of the "sudo iwpriv" commands, I get:

wlan0        no private ioctls

Any ideas or are RT73s still out of luck when it comes to WPA? Thanks.

Thank you for this, it worked perfectly for me!

Help! I'm using Hardy and I upgraded some packages this evening and a restart was required. On restart wireless and sounds are gone. Looking at another thread here's the output from terminal -

jeff@jeff-laptop:~$ sudo iwconfig
[sudo] password for jeff:
lo no wireless extensions.

eth0 no wireless extensions.

jeff@jeff-laptop:~$ sudo iwconfig eth1
eth1 No such device
