Configuration: two 921s running off DPP44 switch with separators plus a 510 and a 311. Background: My 510 and 311 have never had problems. I had lots of problems on both 921s as below until I read here to use ports 1 & 4 on the DPP44. That seems to have solved it completely on one 921 but I still have a problem on the other 921 as follows. Current problem: One 921 will lose satellite lock at least once a day. When I get home from work and turn it on, it generally will have the "lost lock" message on the screen or a black screen. The guide will still work as will viewing of DVR material that was previously recorded; however, the system is very sluggish during this time. Even when I have lock, sometimes just channel surfing will result in a "lost lock" or black screen as described above. Fix: About half the time, I can get the 921 working again by simply disconnecting the satellite cable from the receiver and then reconnecting it (without having to reset the receiver). If that does not work, I can pull the smart card and reinsert and that reboot will usually do it if the simple cable disconnect/reconnect did not. I find that I usually do not have to fully power cycle the machine to get it running again. Extra info: this box is probably 250-260 feet from the LNBs. I know that is beyond the rated distance. However, if I do a signal check when everything is working, the signal is the same as on my shorter runs. I do have a simple line amplifier at a break in the cable between the switch and this receiver. It does not seem to make any difference. I had my installer pull brand new 2200GHz RG6 to this receiver so I know the cable is not bad. We are using Digicon connectors on the cable. Questions: does the behavior match the problems one would expect from a "too long" cable run? Why does simply disconnecting and reconnecting the cable frequently solve the problem? Is there anything I can do to extend the 200 foot limit? My installer says that using RG11 from the switch to the dish won't help since I'd still need RG11 from the switch to the receiver. I have gotten nowhere with Dish tech support and I have suffered through this for months. Any guidance will be greatly appreciated.
