Warning this is strange. I have a Sear Craftman 1/2 HP Garage opener. I recently installed it to correct a problem that I had with my old unit. The problem is the remote to open the garage only works if you standing directly up under the unit. I had this problem with the old one and it last about 3 weeks. Then it went away just as it came. The last thing I recall doing to resolve the problem the last time was unplug my DSL internet connection. (The DSL unitl sits in my office about the gagrage opener.) But now I don't have the DSL unit anymore. Any Ideals?
