Level J
I have BSNL broadband & modem+router provided by them. I want to use WiFi in Linux.

But thing is I have to use it in Bridged mode, not in PPPoE.

when I clicked on network manager, it shows networking is disabled. how to enable it ?

Please tell me how to do this.

Thanks in advance.

What version of linux and what hardware? You might have to attach a LAN cable temporarily to install wifi drivers after runnign "Hardware manager" in the system menu...
 
As suggested by a member here post your lspac details

type > lspac in a terminal and copy paste the details here.

Rest wont be much of a problem.

I have a ready made guide if your networking card is from broadcom

So you have Intel Advanced-N 6200. it should be supported out of the box in Ubuntu 10.10. so I am not sure what's going on. btw, what happens when you do

Code: 
$ sudo /etc/init.d/networking stop

$ sudo /etc/init.d/network-interface stop

$ sudo /etc/init.d/network-manager stop

Code: 
$ sudo /etc/init.d/network-interface restart

$ sudo /etc/init.d/networking restart

$ sudo /etc/init.d/network-manager restart

?
 
One option you could try is install the non-free drivers, even for my Inspiron 14R i had to install the non-free drivers to get it working. You can check for any other drivers and install it using the below option,
System > Administration > Additional Drivers

Thats ur wireless card. Its strange since being from Intel it should have been supported straight out of the box.

If you can connect to LAN ...go online and do what Napster said.
Compatible drivers work most of the time.

Also, read Up here...This may help

Yup, thats what I tried to suggest too. Any luck @OP ? Your response was "latest ubuntu 10.10 and all drivers installed" ? what were the drivers installed? if you run the "additional drivers" program again does it show further options?
 
Sorry, exams are going on so couldn't reply. Right now I am on Windows, will post results asap.

& btw Additional Drivers suggests only one driver, i.e. for my nvidia card. that is also installed.
 
Assuming the wifi is working on windows right? Can you try enabling/disabling the wifi chip using the hardware button/switch :D Sometimes that kicks it on in the linux side... Try this both when booted in Windows and also when in Linux.

Yup, working in windows with no problem. And Checking hardware switch was first thing I did when I started facing problem.

No, I already have that file. here are it's contents :

Code: 
auto lo

iface lo inet loopback

auto dsl-provider

iface dsl-provider inet ppp

pre-up /sbin/ifconfig eth0 up # line maintained by pppoeconf

provider dsl-provider

auto wlan0 

iface wlan0 dhcp inet

I removed all lines except first two, rebooted the system. No changes. (and restored it to earlier state)
 
ok another request, post the full output of the "dmesg" command here... maybe the wifi hardware has some conflict/error in driver or something...

--- Updated Post - Automerged ---

And have you read the links posted already by sgx100, especially this one which seems likely procedure to follow: [ubuntu] Intel wireless card not detected - Ubuntu Forums

Please follow that thread and post back your results...

For example, go to Applications -> Ubuntu Software Center -> Edit -> Software Sources. Select all the items in the "Ubuntu Software" tab , then in the "Updates" tab enable the "maverick-backports" option. Click close and it will take some time to update all the package source information.

Then in software center search for "backport" packages, and try installing at least these two:

linux-backports-modules-wireless-maverick-generic

linux-backports-modules-compat-wireless-2.6.36-maverick-generic

And post your results or followup questions...
 
Sorry to interrupt this thread but...

My eMachines E725 has a Broadcom WiFi card.

Not been able to use WiFi.

Running Linux Mint 9.
 
Same things MHG, post output of "dmesg" and also if Mint has some program like "Additional Drivers" or "Hardware Manager" which lets you install 3rd party drivers then try it and see...

I used ndsi wrapper to install wifi drivers downloaded for windows xp from emachines support site.

Will check and see how it works...
