Wireless-G PCI Adapter w/SpeedBooster.

Not being a computer geek, I was a little intimidated by the instructions but the installation went flawless and with ease. It was a piece of cake to install and started working immediately. The wireless hook up is great.

It's not worth mentioning anything about the instructions, so there was no cons.

It takes a few seconds for the pc to pick up the signal from the wireless router. So you can't just jump in and start surfing. You have to wait until the signal is picked up.
