How do I block neighbors from stealing my wifi?
I am new, and this is my first forum question - hopefully I will post some instructables soon!
My dsl speeds have become very slow in general and horrible at certain times of the day. Of course, this could be caused partly by the daily cycle of general usage in my area, however I suspect that some neighbors are piggybacking through my wifi and killing my bandwidth. One reason for this is that even when my computer is off my modem registers activity.
Is there anyway to block this either mechanically or otherwise? One key is that we live in a house where there is only one possible direction that people could hijack from - everyone else is way to far away. (unless, of course, they have been hanging out on this site and are using collanders and coffee cans...)
For mechanical, I was thinking some kind of directional metal shield. I don't know if this would work, though. (my computer is opposite from the other houses so it wouldn't block me.) Any advice, or instructable how to do this would be appreciated.
-btw, I wouldn't mind sharing if I didn't think it was killing my dl speeds....
