can i hook up a wireless usb network adapter to the EL1333G01w.

By using a wireless adapter, you are free to move your computer anywhere in your home that you'd like and will still have access to these important networks. Most new computers come with wireless adapters built-in, but if you've had to buy one separately, you'll have to hook it up in order for it to work.
Plug your wireless USB adapter into an open USB port on your computer. If you've purchased a wireless USB adapter, all you have to do is connect it to any USB port you have. It doesn't even require a power cable; it uses your computer as its power source.
You will need to buy an internal wireless adapter, you will have to open your case to hook it up. Completely turn off your computer and unplug it from the wall. Pull off the side of your computer's case and look for an empty plastic slot near the bottom of the machine. This is called a PCI slot, and it is used for connecting new hardware to your motherboard. Plug your wireless adapter into the PCI slot, seal up your computer and turn it back on.
For more specific information on how to install hardware components to your specific model of computer, consult your computer's user's manual.
Install any software or drivers that came with your wireless adapter. No matter which kind of wireless adapter you've purchased, it will come with a CD, DVD or flash drive filled with important software necessary for the operation of the device. Put the CD or DVD into your computer's disc drive (or flash drive into a USB port), and install the software. Restart your computer to complete the installation.
