[ubuntu] Can't connect to internet

[Rad1]

Ubuntu installed surprisingly easy.

But I haven't been able to connect to the internet.

Been hacking away for hours. No dice.

Even took my laptop to a coffee shop (where I am now) that has free wireless with NO password (wireless network at home has WEP).

Still cannot connect.

Does Ubuntu have a utility that scans surrounding area for wireless networks and lets me click on the one I want to connect?

At one time, it even said I was connected to the wireless network at the coffee shop, but I was still not able to load any web pages in Firefox, (except for those resident on my hard drive).

I think that might've been when I enabled 'Roaming' but not sure, cuz I've tried so many different configurations.

Their wireless network is working cuz I'm using it now (from Windows).

Is there something I'm missing?

Can you post the output of

sudo lshw -C network

I know you'll either have to type it or transfer it on a flashdrive or similar, but it'd be best.

What flavor of Ubuntu do you have?

On Ubuntu and Xubuntu there is a monitor-like icon in the panel that will let you choose a network and fill in the pass (if you need any).

Hi. Thanks for replies. I have Ubuntu Desktop 8.04, downloaded and installed yesterday.

Can you post the output of

Uh, where do I enter this? Not sure what you mean about flash drive. I don't have one, but I can buy one if you think it would help. (I have a FAT32 drive for files going back and forth between Windows and Ubuntu .. if that's what you mean.)

I've been using the icon at top-right, if that is what you mean, but it does not tell me what is out there. It only lets me input settings, which seem to be wrong, since I can't connect. Is that the icon you are talking about?

Press "Alt+F2", open 'gnome-terminal', paste command and hit Enter.

Are you sure that your wireless has firmware installed ?
Please post the output of

lspci
ifconfig
iwconfig

in terminal (under Accessories)
To scan for networks in terminal enter the command

iwlist scanning

I'm only sure that I've been able to connect to the internet wirelessly for a few years now using Windows XP. Does that mean I have firmware installed?

[Kevbert]

No. With Ubuntu it's software thats stored initially in the /lib/firmware directory. What you have to do is install drivers into there. First we need to find out the chipset that your wireless card is based on. The first command will tell us more about your system (lspci = list pci devices). The second two commands tell us whether the wireless card is on and can see networks (but not which ones).

[gjoellee]

maybe your wireless card is Windows only or something (just a guess)

[Rad1]

Okay, I'm starting to see what you mean.

First, lemme say thanks for the support. It's true what they say about the Linux community.

Next, I am a little nervous about posting all this network info. Does it open me up to hackers?

Here's the info. For some reason the formatting got weirded out in notepad. But here it seems okay again (normal). I'm confused. Why does it look so different in notepad? .. with no spaces, or linebreaks?

The separate commands are identified by > *** command *** for easier visual browsing.
