Ubuntu Internet Connection Issue

[Tsalagi]

Howdy! I'm new to Ubuntu. I've decided to install it and get to know it to gain some knowledge about Linux and operating a development environment. I followed a tutorial on how to download, burn the ISO and install Ubuntu, which was very helpful. All went well with the install and I can boot up Win 7 or Ubuntu from the boot process. I soon found that I could not connect to the internet under Ubuntu but I can under Win 7. Ubuntu doesn't see the network I have set up for Win 7. I set up a network connection using Ubuntu connection wizard with all the appropriate information but got nowhere. Here are some details. If I need more info, please tell what info I need and how to obtain it.
I have a Dell 1750. OS Wind 7 Professional. 350 gig HD, Intel Core i3 CPU, 4 gig DRAM. Under Windows System I see two network adapters. Dell wireless 1397 WLAN Mini-Card and Realtek PCIe FE Family Controller. There is also a PCI Simple Communications Controller with an Astrix. I think that is for a modem and is not pertinent to this issue.(?)
Under Ubuntu I don't know how to find system devices that Ubunto is running with drivers installed and operating. Any help would be appreciated. Thanks!

i assume you are trying to use the wireless connection? some chipsets still require firmware, start here

Yes. That is correct. Thanks for the link. I'll stop by and post how it worked out.

if you see your wireless card and network card in the lspci but your drivers are not installed by ubuntu, I would suggest that you first try this. open up /boot/grub/grub.cfg as root. just open a terminal as root and type gedit and open the file. on the kernel line under the first ubuntu menuentry, should start with linux /, add acpi=off to the line and save it. then reboot and see if this fixes your issue, this worked for my laptop since it detected the devices but wouldn't load the drivers per the acpi issue.

I really appreciate your post because it sounds much more simple than what I have been reading. However, I think I need to find a tutorial on Ubuntu before I start all this because I don't understand any thing you said. Can you compare it to Windows actions?

1. Go to Applications > Accessories > Terminal
2. Type sudo gedit /boot/grub/grub.cfg
3. It should prompt you for a password, enter it then press enter. You won't see any dots or asterisks or anything while typing.
4. When gedit opens, find the lines that hatebreed indicated and edit them. Save the file and exit gedit and reboot.

Subtle_Demise thanks for the direction. Just poking around I've learned a bit.
I tried hatebreed's command line and all is the same. I ran some troubleshooting directed by Ubuntu help and the script return info that my wireless card is detected with drivers installed but my network is disabled. I'm able to connect with Windows 7 my dual boot win/ubuntu and two other machines Vista and xP. I'm using a Linsys WRT54G router but I don't know what else I can do to get this OS up and running. I have to wonder with all the other issues I've read about with Ubuntu and other distributions of linux if it is really worth the time and effort. Especially if this kind of thing happens with releases determined to be stable. I'm going back in and poke around again. Any suggestions would be appreciated.
Thanks

go to the terminal again type in ifconfig. this will tell you what your ip is or if you even have an ip. if your not connecting to the net then the latter is probably the case. if you don't have an ip then type ifconfig eth0 down and then ifconfig eth0 up and see if it sees your ip or not, this is assuming that your network card is eth0.
