Cannot install Ethernet card on laptop

Due to extensive corporate espionage, an obc domain investor and Paypal account holder cannot install the Ethernet card on the Samsung RV 513 laptop. It appears that NTRo/NSA officials have hacked the laptop using sophisticated equipment and the device manager is giving an error for the network controller.
This has made it difficult to install the ADSL modem on the laptop as an ethernet connection will be needed to connect to the adsl modem and the internet.
All other internet connections seem to be working fine
