+1, I had this issue as well and went through a bunch of futile efforts to block the sun and the angle and wish I had replaced the transmitter a lot sooner instead of trying to move trash cans because that worked 50% of the time.

I don't mean to start a flame thread, but people moved away from Apache precisely because it's too heavy and slow. Nginx should work much more smoothly, unless there's some dynamic backend bottlenecking instead (and even then, Nginx' buffering frees up the backend faster).
Thank you! I was trying to do that but couldn't find information on their policy about accepting and hosting such data. I've added links to this as well as Torrent links other folks had sent.
