The D-Link DWL-G132 and gaming feasability

Being faced with the choice of getting Comcast for $20 a month or paying $20 to forever access the wireless network that is already in place, the second choice doesn't sound half bad. However, I am a regular gamer, and I have heard that any wireless connection is a nightmare to game on.

I am curious if the D-Link DWL-G132 would allow me to game without too much difficulty. I play both RTS and FPS, so erratic connection speed or losing the signal are both concerns for me. If the D-Link isn't up to snuff, what do you recommend? If you need any more information about my network or the like, I'll provide it as needed.

Thanks in advance guys,
