I dont know much about this, but I think that a wired connection from the router is going to be faster than the wireless connection anyway. Also you are using an 802.11b router which I think for wireless connections is pretty slow anyway. I use a 802.11g router to hook up a desktop(wired), a laptop(wireless) and a ps2(wired) and it is fairly quick, but not as fast as a direct connection to the modem. You could disable the ethernet connection on the computer with the wireless connection but I dought you will get any more speed, Make sure you just disable the connection not delete it (just in case).
