Welcome to Ask Ubuntu!

Ubuntu may have not installed the proprietary drivers you need. This is because Ubuntu tries to stay free by itself, but these drivers are non-free. However, they can make your computer work better.

To do so, open up the Ubuntu Software Center. It's the icon that sort of looks like a shopping bag (with explosives).

Move your mouse over the bar at the very top and click Edit. Select Software Sources.... Give your computer a second to crank, and then a window will appear called Software Sources. Select the tab labeled Additional Drivers. Let it load, and if any drivers appear, tell Ubuntu to install them.

If the list is empty or all of them are in use, open a terminal by clicking the Ubuntu Logo on the top left and typing "terminal". When the black window opens, run these commands: lspci and rfkill list all. Edit the question and tell us what it said.

dell inspiron 1545 uses broadcom wireless.

Following installed wifi on my dell inspiron 1545 in Ubuntu 12.10

sudo apt-get install linux-headers-generic
sudo apt-get install --reinstall bcmwl-kernel-source
sudo modprobe wl

You may need to prss Fn+F2 (1 or more time ) to enable wireless. Check the network manager on panel after every press.
