a "wireless card" is a network card that receives a high frequency signal from a wireless router or wireless access point. Same as an Ethernet Card/Network Interface Card(NIC), only wireless. A wireless Card is a network card which connects to a radio-based computer network, unlike a regular network interface controller (NIC) which connects to a wire-based network such as token ring or ethernet. A wireless Card, just like a NIC, works on the Layer 1 and Layer 2 of the OSI Model. A wireless Card is an essential component for wireless desktop computer. This card uses an antenna to communicate through microwaves. A wireless Card in a desktop computer usually is connected using the PCI bus. Other connectivity options are USB and PC card.

Are you asking if the computer will get internet? If so... Yes. as long as the router is connected to a modem via network cable and also connected to the desktop computer via network cable.The computer will not connect to the wireless signal sent out by the router. Without a wireless card, it will only work if it is hard patched via network cable to a working modem. If you are asking if the wireless router will still work, even when its connected to a desktop computer with out a wireless card, the answer is also yes. and i this situation, a wireless card in the computer is completely irrelevant so I'm guessing this is not what you meant.
