Booted LiveCD on my laptop. No issues. Booted on my desktop. Issues. #1, when the try ubuntu page presented, the text was garbled. #2, could not connect with wireless even though all information was entered correctly.

What can I provide that will help you help me?
Thanks

When you say "try ubuntu page" what do you mean?

You said when you booted LiveCD on your laptop, you had no issues. But the problems were with the desktop. I would have thought any wieless would have been associated with the laptop not the desktop. Don't you have a wired network with the desktop? Or do you have a wireless card in the desktop? It would be nice to have more information on your system you are having problems with. and that includes the video card also.

[lmart]

Thanks for your replies.

#1 When you boot the LiveCD, a page is presented that has 2 options; Try Unbuntu & Install Ubuntu.

#2 My laptop and desktop are both wireless. The LiveCD connected to the laptop wireless without a problem. No so with the desktop wireless. Triple checked all wireless parameters and they were correct.

With that said, what do you need to know to help me connect the wireless on the desktop. Additionally, since the "try ubuntu" page comes up garbled every time on the desktop, my sense is there is something wrong, but I have no idea what it is or how to check any log that might give a clue.

[irv]

Could use a little more information on the desktop. What brand? Dell, IBM, etc? or is a home built one? What is the graphic card? Can you plug in a network cable? You may need to do this to try to get the wireless to work. It may need a driver. For some reason, the wireless card may not be supported or the driver for it is not loaded. You can check support for hardware at: https://wiki.ubuntu.com/HardwareSupport/
There is a link to wifi support on this page. Also video cards.

Hope this helps.

Have you checked your hardware against the Hardware Supported list in the link above?
I see you have a network card so you may need to hook a wire up to it to get on line. I don't know if it is seeing your USB wireless. Also this is what it said about your video card.

I believe you can boot from the live CD in lower video mode by pressing one of the function keys. Maybe F6?

@lmart, to help you with the usb wireless device, we need the whole output that lsusb gives you. This:



USB Devices
UHCI Host Controller
UHCI Host Controller
UHCI Host Controller
Microsoft® Nano Transceiver v2.0
EHCI Host Controller
Compact Wireless-G USB Adapter

If that's from the output of lsusb, you've cropped out the most important bit - the ID number - without which we cannot identify the wireless chipset.

Please run "lsusb" from the terminal, highlight the whole of the output with the mouse, then right-click -> copy, and then paste it into your post. Post the output between
and tags to preserve formatting and for clarity. The simplest way of doing this is to highlight the output and then click on the http://ubuntuforums.org/images/editor/code.gif button in the message toolbar.

@coffeecat

thanks for your reply

if there is anything else you would like me to do to help, please let me know

[coffeecat]

That's a strange lsusb output - a lot of it seems to be missing. Anyway, this line:


Bus 001 Device 004: ID 13b1:0020

Identifies your wireless USB device. According to this Debian wiki page (http://wiki.debian.org/WiFi/rt73), that ID refers to:


USB: 13B1:0020 Linksys WUSB54GC v1 802.11g Adapter [Ralink RT73]

I would have thought that would have worked in 12.04, but I don't have any recent experience of Ralink wireless devices. Perhaps someone with experience of that device will be able to help you.

[lmart]

@coffeecat

Thanks. Copied the exact output from lsusb.
Assuming I wait until someone responds to my post, correct?

Assuming I have to load a driver, is there a tutorial that provides a step-by-step for the process? Never added a driver before.

[wildmanne39]

Hi, please try:

sudo modprobe -r rt73usb
sudo modprobe rt73usb nohwcrypt=Y
Watch for errors.

If it does not come on post the output of:

cat /etc/lsb-release; uname -a
lspci -nnk | grep -iA2 net
iwconfig
rfkill list all
nm-tool
by clicking on new reply and click # then paste the information between the brackets.
Thanks

@wildmanne39

Using the LiveCD, how do I get into the terminal to enter these commands?

@wildmanne39

Using the LiveCD, how do I get into the terminal to enter these commands?
There should be an icon in the dash to launch the terminal. If not just hit the super key (windows key on the keyboard) and start typing terminal. When it shows up just click on the icon.

Hi, ctrl+alt+t.
Thanks

[lmart]

@irv & @wildmanne39
Thanks for your help getting me into terminal. Completely forgot about right-click on mouse.

@wildmanne39
thanks for your suggestions, fyi

1. my computer hung/froze on: sudo modprobe -r rt73usb
2. my access point: 398VC
3. completed your request (below); have absolutely no idea what these commands do, where can I go to learn?

fyi, a notification pops up to let me know to connect to my wireless, it identifies my access point and requests the WEP key, enter the key, the arrows go around in circles for quite some time, then it requests the WEP key again, and the circle continues

[wildmanne39]

Hi, which network are you try to connect too?

To learn about commands you can type man plus the name of the command into the terminal and it will tell you what the commands do.

After you ran the
sudo modprobe -r rt73usb
command did you run this one:

sudo modprobe rt73usb nohwcrypt=Y
Thanks

[lmart]

@wildmanne39
thanks, 398VC
didn't run the 2nd cmd as the 1st crashed
just ran sudo modprobe rt73usb nohwcrypt=Y nothing happened

[wildmanne39]

Hi, what do you mean the first crashed? exact error message please and the commands are meant to be ran one after the other.

Which network are you try to connect too?
Thanks

[lmart]

@wildmanne39
thanks

sudo modprobe -r rt73usb
this command caused my computer to freeze up, I had to turn it off then re-boot
sudo modprobe rt73usb nohwcrypt=Y
this command simply returned to the command prompt

no error message on either command

Which network are you try to connect too? 398VC

[wildmanne39]

Hi, that may be because you are running ubuntu from a livecd I have never seen that happen before, also remember that a live cd runs slower it could have just needed more time.

I recommend going into your router settings and changing encryption to wpa2 only if you have that option because some linux drivers do not like wep very much.

You will also need to change your settings in network manager to wpa/wpa2 if it is setup for wep.
Thanks
