I'm an installer so I've had my share of knowledge with Directv's equipment however I'm having the craziest problem that I have never seen on a service call and have my service dept scratching their heads. I have 2 HR-24's and an HR-22. The 22 keeps disconnecting from the network. I've swap receiver deca's, switch, LNB, ran new cable twice and still having the same issue. I've even checked the voltage in the house! Anybody have any thoughts or should I just call ISS and have a new receiver drop shipped to me?
