Hi and welcome to the forums.

Have you tried clicking the network manager icon and clicking both Enable Networking and Enable wireless? Those two lines act like on off switches.

Have you used the Additional Drivers utility to activate any additional drivers? There might be an icon of a pc expansion card to the top panel. You can find this utility in System Settings or type a seach for it in the Dash. It is an Installed program.

Regards.

Yes I did find the enable wireless network and enable network tabs at the top of the bar, this acts like something is not correct in the set-up or some kind of compatibility
I will try what you suggested, many thanks for the welcome to this great forum

Shouldn't need additional drivers. Is it the original iw2100/2200/2915 that came with the laptop? If so, that driver has been included in the kernel for the last few years.


does a:


dmesg | grep Intel
or


lspci | grep Wireless
yield anything? If so, make sure the kernel module is loaded.


lsmod | grep ipw
(The above code blocks assume you have an Intel PRO/Wireless card, 2100, 2200 or 2915)

wow this forum is amazing.
many thanks for the quick replies.
below is what I got when I tried the commands you sent.

gordonmartin@ubuntu:~$ dmesg | grep intel
[ 0.493340] agpgart-intel 0000:00:00.0: Intel 855PM Chipset
[ 0.548231] agpgart-intel 0000:00:00.0: AGP aperture is 128M @ 0xe0000000

gordonmartin@ubuntu:~$ lspci | grep wireless
gordonmartin@ubuntu:~$ lsmod | grep ipw
gordonmartin@ubuntu:~$

as far as I know it should be the original wireless components inside the laptop

ideas ?

many thanks for the help

Hmm, now i'm trying to figure out which wireless card is in your machine. My 8600 at home has a Intel ipw2200BG, but it seems this is not the case for you.

Was/is there a Centrino sticker on it? That sticker means it shipped with an Intel CPU & wireless card. Yours may have shipped with a Dell TrueMobile card. We need to find the make and model to ensure the correct driver is being loaded.

Would you be able to post the output of lspci?


lspci

Yes I can post the output to that command
I will try and look further for what kind of wireless card is in this unit.

again

many thanks

under the dell support page listing the original equipment
i found the following listing
3X548 Card, Wireless, Mini PCI Card, Internal, BROADCOM CORPORATION..., 5GHz

I do not know if this would help

See the last line in your lspci output. That is the wireless card, A Broadcom BCM4309 a/b/g. (Also called a Dell TrueMobile D400/410/600)
Now we need to see if it has a driver and if it's loaded.

can you now try:


lsmod | grep bcm
Should let us know if the driver is loaded. If you get nothing, just post the output of lsmod and all currently loaded modules will show. It is possible that there is a module conflict somewhere.

If you see a bcm module loaded, post the output of:


iwconfig
and you can check if the wireless radio is at the very least on.

Looking around, Broadcom never released the info for a proper open source driver to be created, so bcm43xx is a reverse-engineered one. People have also used ndiswrapper to get this card working. I have no experience with it, but there are plenty of guides on the forum if you need to go that route. It is a last resort option though, as it can be really messy.

i believe I understand what you are pointing out.
Below is what I gleemed off of the commands you sent.

ordonmartin@ubuntu:~$ lsmod | grep bcm
gordonmartin@ubuntu:~$ iwconfig
lo no wireless extensions.

eth0 no wireless extensions.

wlan0 IEEE 802.11bg ESSID:off/any
Mode:Managed Access Point: Not-Associated Tx-Power=0 dBm
Retry long limit:7 RTS thr:off Fragment thr:off
Power Management:off

gordonmartin@ubuntu:~$
it would appear that the wireless system I have in this dell Inspiron 8300 are not supported.
I will try what you suggested and see if I can look thru the forum for some guidance in that area.
many thanks for all the responses and help.
I had to reload Ubuntu because I tried downloading something that I thought would work and ended up knocking myself off the network wired and wireless.
I am in the sharp learning curve of Ubuntu I am afraid

again
thanks

Ahh, looks like there is a driver installed, but no connection is present. I still don't know which driver it is using though...

For instance, when I'm not connected to a network I get:


wlan0 IEEE 802.11abgn ESSID:off/any
Mode:Managed Frequency:2.412 GHz Access Point: Not-Associated
Tx-Power=14 dBm
Retry long limit:7 RTS thr:off Fragment thr:off
Power Management:off

And when connected:


wlan0 IEEE 802.11abgn ESSID:"NOTREAL"
Mode:Managed Frequency:2.412 GHz Access Point: 14:D6:4D:A9:5F:D0
Bit Rate=117 Mb/s Tx-Power=14 dBm
Retry long limit:7 RTS thr:off Fragment thr:off
Power Management:off
Link Quality=59/70 Signal level=-51 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:37 Missed beacon:0


When you click the network manager icon on the top bar, make sure wireless is enabled, then see if there are any networks around. Then maybe try connecting to a hidden wireless network.

Also, the current state of Broadcom drivers in linux is a bit wishy-washy. Looks like bcm43xx has been removed from the kernel (2.6.26 according to wikipedia). b43 is still there, but might use experimental open-source firmware. Still idk what driver you're on.

If you come back, can you post the output of:


lsmod


I really want to find that driver...
