Wireless Internet is always a pain to get right. Look at tech specs for your computer and find out what kind of wireless card it has, then search Google for how to get it working with your card (you might be able to just search for how to get wireless with your computer name) You'll probably have to install a driver, and maybe use ndiswrapper.
But yes, Ubuntu can connect to the Internet wirelessly.
I had the same problem with Ubuntu Studio. I don't have the installation handy so I will be guessing at the name here but I think you have to cable up then install a package called (I think) widi. My problem was that every time I tried to enable the wireless connection by setting the authentication type and access key, the setting were discarded. After I installed widi I was able to set and save. My Ubuntu is on an external drive (I boot to USB when required) and I do not have the drive here right now. If I am incorrect about the package name I will correct it shortly.
By the way, this fix was difficult to identify and in my opinion, should have been included with the default install. But then again, I am a Linux noob so the fault may be entirely mine.

My mistake. The package you want to install is "wicd" and is described in Synaptic Package Manager as:
Wicd is a general-purpose network configuration server which aims
to provide a simple but flexible interface for connecting to networks.
Its features include:
wide variety of settings.
* ability to connect to (and maintain profiles for) both wired and
* support for many encryption schemes, including WEP, WPA, WPA2 and
* wireless-tools compatibility;
* tray icon showing network activity and signal strength;
* lack of GNOME dependencies (although it does require GTK+), making it
easy to use in Xfce, Fluxbox, Openbox, Enlightenment, etc.
This is a metapackage, it allows installation of all the components of
Wicd, including one of the clients, which must be manually chosen.
When I installed Ubuntu it automatically found my wireless network. I just had to enter my password and I was on. I had looked up how to connect a head of time and watched a video on Youtube because I had some previous Linux experience at a different house and didn't think that Ubuntu would find and connect like this.
However keeping it up and running is another matter. Worked fine for the first 5 months or so. Over the last 4 or 5 I have had about 10 times where all the Windows computers in the house could connect but my Ubuntu couldn't and had to restart my router to get it too work. Other then this simple but annoying issue no problems.
Normally for I would install Ubuntu restricted extra first after a fresh install and than I will check for driver with "Additional driver" to install any driver that has not been install. I do this with cable plug in and after everything has been isntall than only I will use the wifi connection. So having a network cable around is handy.
