let the download go through as a single lnb. 101 only. then when all thats done, go reconfig for slimline 3. it will go through the process again. when it says problem with 103 select (continue fix later). This won't be available until you get both boxes downloaded. When all that is done check your signal on that 103 lnb. In my area it does the same thing sometimes. we use two 99's for nour programming and 103 really has nothing to do with anything. It might be different in your area. And that is not always the case, just sometimes. Let us know what happenned. If that doesn't work change the LNB. If that doesn't work re-run the lines. if that doesn't work change the boxes. now everything is new. if it still doesn't work
Jk look for obstructions in your line-of-sight. If you have none, QUIT YOUR DAY JOB!!!
