[SOLVED] Another Question... (Regarding Internet)

[kwatson30]

Sorry I have another problem...

Since I live in an apartment, I had to set-up everything wirelessly. I have a wireless card in my desktop that I use to connect to my router, but for some reason I can't connect wirelessly. I could connect when I was on Windows XP, but now it won't when I'm using Ubuntu. My laptop, phone, ps3, etc. can connect to my router but my desktop can't. I know its not the router, because I have it set to open... so not sure what's going on--can anyone help?!

Thanks again in advance!!

[kmitnick]

it is about the wireless card,
you need to install the ubuntu compatible drivers, what kind of wireless card is it???

[reed9]

As kmitnick said, it's almost certainly the wireless card. In most cases like this, there is some proprietary drvier or firmware that's needed. We need to know the chipset of the card and some other info. Please read this thread to find out how to gather all the necessary information.

Hey guys, thanks for the responses. I have looked at the thread that was provided, and I have a few questions so I can provide you guys the information you need to help me out... Do I need to enter the code 'lspci -nn' in Ubuntu or in Windows? To maybe help you a bit more, I'm using a LINKSYS PCI Wireless card. Also, do I need to be connected to the internet to receive this information?

Sorry about the troubles... heh.

Enter it in Linux and no you don't have to be online to get the info. Basically it just calls on your computer for the information and spits out a bunch of info. To get the actual driver....there's a good chance you'll have to be online in Ubuntu (wired up) or you can download the stuff to a thumb drive and install from that but that can be a hassle.

If you can wire up just go to system->administration->hardware drivers and see if it detects anything to install.

[kwatson30]

Okay, I wired up and went to system ->administration->hardware drivers and I installed 'Broadcom B43 wireless driver', but still nothing has changed. Here is what 'lspci- nn' gives me in terminal.

Ubuntu should have the b43 driver installed already. What you need is the firmware as well, which Ubuntu doesn't ship.

If you can get a wired connection for a few minutes, you can get the firmware as follows

sudo apt-get install b43-fwcutter

During the install process it should ask you if you want to download and install the firmware.

If you can't get a connection, you need to download the .deb package, which you can get here, then the firmware, and get it on your Ubuntu box, using a flash drive or external drive.

You can get the firmware here.

More info on this and how to extract the firmware: b43 - Linux Wireless

There's also a proprietary driver released by broadcom, but I'm not sure it works with the 4306. However, Ubuntu might be trying to load it, in which case it will conflict with the b43 and you need to blacklist it.

Post of the output of

lsmod

Ubuntu I think also blacklists the b43 driver by default, so check for a line reading blacklist b43 in /etc/modprobe.d/blacklist. If it's there, either erase it or comment it out. (Place a # at the beginning of the line. You need root permissions to write to the file. You can open gedit with root permissions as so

sudo gedit /etc/modprobe.d/blacklist

[jmadero]

if he went through the hardware drivers it would have installed b43-fwcutter

did you restart after installing? If it sees the broadcom chipset in the hardware drivers then you shouldn't be getting a problem. Restart, go back into the hardware drivers and see if it's green (I believe it changes color) and somewhere it should say in use or something like that

Thanks guys!! Got it to work!! Starting to really love Ubuntu now!!

[jmadero]

please tell us how so others can see where you snagged. Glad it's working After you say how please mark as solved also
