You sound like my brother. I swear he emits a wifi-disruption field around his person. We can be in the same house connected to the same router and I'll have 180 days of perfect pings and no dropped packets and he'll get 10 connection issues in an hour. Doesn't matter which computer he uses or where he goes, always with the bad internet. Meanwhile the last time I can remember having serious wifi troubles was way back in 2005 when I had a crappy netgear router that had to be reset once a day or it'd go a little funky on me.
