Hi guys,

I just bought a Dell Inspiron 1545, Intel Core 2 Duo T6500, 2.1GHz, 800Mhz, 2M L2
running with Window 7 64bit

Installed Ubuntu 9.10, all working except wifi. I cannot see any network (I have a home network, broadcasting and working in window).

My wireless card is a Dell Wireless 1397 802.11g Half Mini Card

Any idea of what I can do?
If you do, please provide me with dumb proof instructions, as I didn't use unix based systems for the last 20 years...:-k:-k:-k

Cheers,
Max

Thanks a lot, I'll try. If it doesn't work, I'll have to come back to windows 7 to reply :roll:

Before you are tempted to frustrate yourself into an early grave with ndiswrapper, madwifi, wicd or anything else suggested in those links, have a look at this thread:

It would seem that you have a Broadcom chipset wireless card and according to the last post there, all you need do is install the Broadcom driver by going to System > Administration > Hardware drivers.

If you have any problems, open a terminal and post the output of:


sudo lshw -C network... so that we can double-check that wireless chipset.

Please, everyone. It's the chipset that matters. There's no point in recommending anything until the chipset is known.

Try going to System > Administration > Hardware Drivers
gives No property drivers fund

while:
I applied your indication:
sudo dpkg-reconfigure bcmwl-kernel-source
sudo modprobe -r b43 ssb wl
sudo modprobe wl


massimo@ubuntu:~$ iwlist scan
lo Interface doesn't support scanning.
eth0 Interface doesn't support scanning.
massimo@ubuntu:~$ sudo modprobe -r b43 ssb wl

massimo@ubuntu:~$ sudo modprobe wl

Shall I scratch and re-install??? I must admit I am a bit lost...:confused:

Any support is welcome!

Do the same, like in the first post and reboot. After this I had wireless.
Let me know what has happened!

I did this on my dell and it worked perfectly until I did a reboot and then my system seemed to forget all the settings? I also went to broadcoms website and they provide a driver and install directions but they also seem to be forgoten after a reboot. Any sugestions?
