Hello everyone,

My processor supports 64 bit OS, so this time I installed Ubuntu 9.10 64 bit version through WUBI. Everything is fine except that Ubuntu doesnt recognize my Modem(even the router's 192.168.1.1 page doest open).

I also noticed that whenever there is some sound played, it produces a sharp and disturbing hiss from the speakers. My sound card is Creative SB 5.1. Same thing applies for GFX card too. Its not detected, i think coz i cant turn up the visual effects, which i could do earlier...

What sort of modem is it? Is this machine a laptop? Most "modern" laptop modems are not real modems, but "winmodems", and as far as I know won't work with anything other than windows.

Mine is a desktop and the modem is an external ADSL Router, through which i connect to Internet. Currently it is connected through a USB connection.

Ok, so your computer does not have a modem.

What is the output of

All this seems to go over my head, but hope you can help me with it

*ifconfig* not '*ipconfig*'

Also, I still need to see what is in /etc/network/interfaces. Ie the output of:
Don't worry, if you pay attention you'll be learning with every command you enter :-)
If I ask you to enter a command, it is a good idea to have a quick look at the man page of that command so that you can get some understanding of why you're being asked to run it.

Although in the case above you would do better to look at the "interfaces" man page.

Cheers,

Evo2.

I just reread the following:
What does this actually mean? You have connected you pc to the router using a usb cable? Can you please elaborate?

Evo2.

Oh Yes, I actually meant that itself. Connected my router using a usb cable.

Well, surely, now onwards i'll be learning more about Ubuntu. I've been for years into windows :P ...and thats the reason I read "ifconfig" as "ipconfig". :P

Anyways, here are the results:

cat /etc/network/interfaces

Hey guys, i'm still waiting for your reply. till then i cant use ubuntu. pls help...!

Ok, I'll bite. Why are you trying to do networking over usb?
Are you sure router supports this?
Why not connect your computer to the router with an ethernet cable?

Anyway. Networking over usb is possible but a little unusual outside of embeded devices.

You need to check if some modules are loaded into your kernel:
If the above command returns nothing you need to load the modules

Now with the usb cable connected between your computer and router enter the following command

If all is well you will see entry like:
If you don't see this entry try disconnecting and reconnecting the cable and issue the command again.

Next step is to configure the device. You may be able to do this with network-manager which may appear as some sort of network icon in your panel/taskbar/systray. However I don't use that sort of thing, instead I would enter the following in the file /etc/network/interfaces

Then issue the command
now please try to test your network:
If that fails try

Ok, please try to follow the above steps and report back if (when) something fails.

Cheers,

Evo2.

If it didn't it would not have a USB ports.
What if the OP's computer has not ethernet cable input?
are the speakers plugged in tight? Is the sound driven in-kernel or a external driver?

The USB port could be for something else. The firmware in the router may not support ethernet over usb.

This is indeed a possibilty... and seems it may be the case for the OPs lspci listing. Although, if there are free pci slots an ethernet card can be obtained for a similar price to a usb cable.

Anyway, waiting to here from the OP.

Cheers,

Evo2.

First of all thanks a ton to both of youfor the reply!

I'd like to tell you, my router's ethernet cable is used by my IPTV(Internet protocol television)set-top-box. So, i am forced to use the alternative(i.e. usb port) for connecting my router to my PC.

Now i'll try the above steps and revert back...

Ok, now everything was going fine until i tried to edit the "interfaces" file. I cant make changes to it. Seems to be some kind of write protection on that file. I am the sole user and hence no other admin is there from whom i may ask access to edit that file, as per evo2's directions.

And yeah, sometimes sound comes proper, but sometimes that same disturbing hiss...have a "creative sb 5.1" PCI sound card.

You need to be superuser. The way this is done in Ubuntu is with the sudo command. For example to edit the file with the gedit editor

Cheers,

Evo2.

Hey first of all sorry for the late reply evo.

I could run my internet from ubuntu after tinkering with some settings here and there. i was able to connect through lan only.

Anyways, i compromised on that. But now the problem is, my Nvidia 9600GT drivers dont seem to work as it doest show my graphics card in the "hardware drivers" section. Moreover, I am not able to turn on the visual effects for the default Gnome environment.

Can you help???
