I bought a Dell Inspiron 545 PC a week ago witha Wireless Network 1505 (802.11 n PCIe Card installed. I also received a wireless antenna. I wondered why I should need one and I noticed the same question was asked some months ago by a community member who wrote (see below)

 

"Hi, I recently ordered a new desktop pc,  including a Wireless Network Card 1505 PCIe 802.11n, which was delivered this morning.

Am I supposed to connect using this stupid antenna?  Why have I paid for a wireless card?  I really don't understand.  I may as well have stuck with my existing system of a cable going into the wireless box from my pc (and another going from the box to the telephone point in the wall)."

The replies she received said that connecting the external antenna to the PC connects it to the card. I have not connected the antenna to the PC yet I have set up wireless connectivity to my sons' PSP and laptop using a D-Link DIR-615 router. should I still connect the antenna to my PC even though everything seems fine without having done so? does this mean my pC has a built in antenna. Sorry if I appear unknowledgeable but I am knew to wireless networks (I've just got rid of my first ever computer after owning it nearly 8 years.
