MSE is yet to cause a problem with wifi in my experience so we can dismiss that for now.
with the test results from xirrus where you at home or school and what where the other access points ?
-74db is not a great signal strength and from approximately 6-10 metres you should be showing more like -30-40db ?
you are sharing a channel (frequency) with another access point so if this at home as i suspect why not try changing the broadcast channel on your router to 3 ?
your router access page should be htt*://192.168.0.1
