Why Can't I Connect to the Internet in Ubuntu 9.04

I have just installed Ubuntu 9.04 on my daughters pc which also has xp installed as a dual boot.

I am unable to access the internet via ethernet or wireless in Ubuntu however when booted into xp I am able to connect to the internet and my home network.

Can anyone please help me work out how to get a ethernet and/or wireless connection working while booted in Ubuntu.

Thanks for your time and help,

In case of ethernet
I will suggest you to right click on wired network connection (top right panel)
(1)Enable networking should be ticked
(2)see connection information.if it shows IP address as then left click on icon & select wired network(though it may be selected still re-select) .
Now you will notice that you get relevant IP,broadcast,subnet mask,default route,DNS etc.

Well there are a couple things going on here. First off, Ubuntu 9.04 was definitely not a great system to begin with. If I were you I would upgrade to 10.04 LTS version. Second this happened to me. It usually happens the other way around but this does usually occur. If it is not detecting any wireless connections then that means that the driver it installed is not functioning or it did not install one in the first place. You may need to go into Synaptic Package Manager under System Administration and look up drivers for your system. If this does not work then you seriously should just upgrade. When you do this do not go through the upgrade process if you can help it. Get the new system put it on a disc and reinstall. There are new options for installing. Hope this helped out your dilemma.

I have had this problem with my netbook. My problem has been that it doesn't install the driver (for some reason it does in the livecd mode but not when you actually install it on your computer.) What I do:

1. Stick a network cable in the computer and your internet router (if its a desktop computer and you can't move things so that you can do this, then what I'm saying won't work for you.) Wait a bit for it to automatically connect to the internet.

2. Click on "System"

3. Click on "Administration" (Or whatever the admin one is called, I'm not using Ubuntu at the moment so I forget.)

4. Click on "Update Manager"

5. Click on "Check" and enter your password if it asks. Wait for it to finish.

6. Click on "Install Updates" and enter your password if it asks. Wait for it to finish, then restart the computer and boot into Ubuntu.

7. Repeat steps 2 and 3.

8. Click on "Hardware Drivers" and wait for the little window to finish.

9. Select whichever driver you need and click "Activate" (or install, I forget what the button says.)

10. It should work after you restart the computer again

I Still have connection problems with 10.04 installed

After a couple of installation errors I managed to get 10.04 installed correctly (found at ubuntu site that the errors were common and able to workaround which i did).

My home network and router are set to static ip addresses.

I have been unable to work out the correct settings to enter in network manager to enable the static ip address connection [wired / edit connections / ipv4 settings] (although i can ping my other networked computers with this setup).

I then changed my modem router setup to enable DHCP and the auto eth0 connection worked straight away and i was then able to connect to the internet.

I then used update manager to system update which worked.

After resteting my modem router back to disable DHCP and allow static ip address assignment I was unable to again set up network manager wired connection and configure the correct settings.

1. (I know my ip, subnet mask, default gateway as I have used these to set up other devices but what is DNS and DOMAIN?)

I then used update manager to load a network program WICD which I thought might make it easier to configire static wired and also wireless.
I was able to use WICD but network manager still aslo seems to be running?

Like network manager WICD automatically connects when my router is set to enable DHCP, but I cant seem to configure it to work while DHCP is diabled on the router.

2. Do I have to unistall network manager for WICD to work properly?

3. Neither network manager or WICD seem to be able to detect my woreless network? Any ideas? (Could my Netgear wireless adapter in my ubuntu machine not be compatible with ubuntu?, it work ok though when running windows?)

4. Can anyone help me set up the wired connection as static ip assignment and or any other good network software which may make wired and/or wireless connection easier?

Thanks all for your help so far, I am loving what i can use of ubuntu, just need to get internet working to be able to use it all the time.

Well I know when I installed a system for someone a Netgear card was giving me troubles. Here is what you might need to do. First, go onto their website and see if they have drivers for it. Second, if the card is old it can be that Ubuntu does not support the card anymore (same thing with graphic cards). Third, if this is the case, get a cheap network card at Walmart and use it. That is what I had to do and it works perfectly. Hope this helps.

How do I use NDISwrapper to use my Windows Driver in Ubuntu 10.04?

My wireless network card is a:-

Netgear WG 311 Wireless Network PCI Adapter

I have the installation cd with the latest windows driver inf file.

How do I use NDISwrapper to use my Windows Driver in Ubuntu 10.04?

I am a total Ubuntu beginner but with help from previous posts I have worked out that using NDISwrapper is probably the only way I will get my Netgear card to work.

I have downloaded and installed WICD (does not pick up my wireless connection)

I have downloaded and installed NDISwrapper.

I have not uninstalled Netweork Manager (should I uninstall it, if I have installed WICK and NDISwrapper?)

Does anyone have simple instructions on how to use NDISwrapper?
