Need some help trouble shooting. I work at a school and we had DirecTv installed through a third party as part of there DirecTv goes to school program. This was over a year ago and one of the boxes will not work now. Originally everything was working when the techs left. Just had problem over the summer. Here is the set up. From Dish down to a 4 way splitter. Leg 1 goes about 20 feet to an HR box. Leg 2 goes about 35 feet to a black power inserter pi21... then to an HD box. Leg 3 goes about 150ft to a two way splitter and that feeds another HD box about 10 feet away and a finally another HR box about 40 feet away. Leg 4 is capped off. The farthest box will not receive a signal. I have checked the box at other places and the box is fine. I called directv goes to school department which is the department there techs call into when they need help trouble shooting and they said that the distance wasn't the problem. Do they make and would a larger power inserter help get the signal to the last box or would moving the power inserter to the last boxes location help get signal to the box? Do you have any other thoughts to try. We will have to call our own third party installer again if we have to but we are a small school and trying to save the money fixing this ourselves if we can. Thanks for the help.
Minor correction: the PI must be connected to port 1 as its the only one that passes DC.
So you're having problem with the leg that has about 200' of coax and both a 2-way and 4-way splitter.
That's right at the limit and seems just a bit over if you're having problems.
Changing the PI location isn't going to do anything.
You could add this after the 4-way: http://www.solidsign...Amplifiers&sku=
Another thing you could try is to have the SWiM channel used by the farthest receiver be changed to a lower channel.
If you unplug all the receivers and the SWiM PI, and then power the PI up and power up the farthest receiver first, this should get it to lock on to a lower channel.
Then power the other receivers up and they'll "snag" the higher channels.
This may have been what was done when it worked and then there was a power outage and with an uncontrolled rebooting the channels changed and your problem appeared [which will happen again]
