I have a Netgear WPN 311, and I'd like to have a better antenna.

I found this Yagi antenna on ebay, and comparing it to similar antennas on the site, it's $20 vs. $100 for a similar item, so I like it.

I read this, and it looks like my wireless card has a Female RP-SMA connector, but the antenna has a Female N-Connector.

Is it possible to remove the Female N-Connector and replace it with a Male RP-SMA?

Is there's a N-Connector to RP-SMA converter available?

Just use a pigtail cable with the corect plugs. These pigtails are ideal to get high gain antennas into position and resolve the connector issue at the same time.

Pig tails are usually really short, you still need a run of coax to go anywhere. Yagi's are directional, so they need to be mounted where they can point in the right direction. Coax cable always has signal loss, that adds up with length, especially at high frequencies like this, the better the coax you use, the better. I like LMR400. The length on those I linked to you is 6 feet. The main reason is that at 12 feet, the coax neutralizes the gain of the antenna, youd have done as well to move your tower to where the antenna is placed.

Perfect Cantenna: Use the big spagetti sauce cans, 3-1/4" diameter. Make the element 31mm long, and place the element exactly 2-1/2" from the bottom of the can. The dimentions are critical, and these are perfect.
