Compaq Evo n1050v Notebook PC Overview
I strongly suggest visiting the above linked page and determining exactly what model in the 1050v series you have. As stated on the linked page, some models don't have a Wireless Network Interface Card (WNIC), just the ubiquitous 10BaseT 10/100 (Mbps) NIC using RJ-45 jacks and plain old CAT5 Ethernet cabling.
If you're having trouble determining whether or not your model is one that does have a WNIC, check the strip of plastic above the keyboard and the front side of the laptop's bottom section for a light indicating the status of your WiFi radio. Your laptop, if it has WiFi capabilities, will use an indicator light shaped like a vertical pole with a small ball on top emanating three waves outward to the left and three to the right.
If the radio is disabled for whatever reason, it will not light up. If the radio is on but you are not connected to a network, it will glow orange. After connecting to a network successfully, it will glow blue. At no point will this indicator light flash unless something is terribly wrong.
Assuming your specific model of laptop has WiFi connectivity, then to enable the hardware you'll need to download and install the requisite drivers (if you haven't already), and lastly you'll have to locate the physical sliding switch which controls the WNIC (on/off) and thumb it over to "on."
