Is there anyway a macbook pro can interfere with a wifi network? For the past week my home network has been experiencing issues. While my roommates and I have no problem connecting to the internet, every 20 minutes or so we are unable to access any website. This period lasts about 10 minutes--all the while, each of our computers show a full wifi signal. At this point you are probably thinking it's a modem/router/isp issue. But when I took my macbook pro to the public library today, I noticed the problem again--as did the others using the free wifi. Upon returning home, my roommate reported that the internet had been working fine in my absence. As soon as I turned my laptop on, however, the problem started up again. The empirical evidence is starting to point in my direction. What could it be? Does anyone have any clues? I'm not running anything special, when this occurs. Just browsing websites on Firefox.
