Wireless Connection on Ubuntu

[AdinaG]

I'm trying to connect to the internet from my Ubuntu laptop. The wireless network is recognized, and the icon at the top of my desktop tells me it is detecting 96% network strength, but I can't load any webpages. Does anyone have any suggestions?

Thanks very much!

[waterhead]

Ubuntu has the option to use non-open source drivers. This may be all that you need to do.

In the main menu open System-->Administration-->Restricted Drivers Manager.
See if there is one for the wireless available.

[AdinaG]

Thanks for the suggestion.

I opened Restricted Drivers Manager (I'm using 8.04, so it's under System --> Administration --> Hardware Drivers), and it told me that "No proprietary drivers are in use on this system".

[waterhead]

OK, now you will need to give more info. Is this an external USB wireless, or is it internal or PCMCIA card?

If Internal, enter this command and post the output:

lspci -nn

For USB:

lsusb

Now, for a list of driver modules loaded in your system, enter this and post the output:

lsmod

Thanks for your help!

By the way, is there an etiquette for posting outputs of this length that I should know about?

[waterhead]

Here's the wireless card:

0b:00.0 Network controller [0280]: Intel Corporation PRO/Wireless 3945ABG Network Connection [8086:4222] (rev 02)

And it is loading the drivers:

iwl3945                89844  0 

iwlwifi_mac80211      219108  1 iwl3945


cfg80211               15112  1 iwlwifi_mac80211

You most likely only need to install firmware for the card. You can get it from here:
http://www.intellinuxwireless.org/iw...e-2.14.1.5.tgz

Unpack it, and place the iwlwifi-3945-.1.ucode file into the /lib/firmware/ folder. You need root privileges, so use the sudo command for that. You can see any system messages, before and then after you install the firmware, with this command:

dmesg

Look for a firmware message. You should reboot after installing the firmware.

By the way, is there an etiquette for posting outputs of this length that I should know about?

You can use the "code" tag for this, and use the "quote" tag for quoting another post.

[AdinaG]

I installed it, and put it in /lib/firmware/, and rebooted, but I still can't view any webpages, even though the network is still recognized. Any further suggestions?

Thanks very much for your time.

[waterhead]

What does the dmesg command say about the wireless?

You may need to now configure it, and enable it.

When you say configure and enable, do you mean through System --> Administration --> Network? If so, I've tried configuring it, both manually, and by enabling roaming mode and selecting the network I'm looking for from the list of the ones it detects, and haven't had any luck.

Thanks again for all your help!

[waterhead]

That dmesg output looks OK. That is basically what mine says, and my wireless works OK.

I think by default Ubuntu uses NetworkManager for network connections. If not, install it and use it.
