New to the board. Howdy!
Having the same problem with an 811 not seeing the 148 bird.
Similar setup to many others... Dish 500 and side Dish 300. DP34 switch.
Have a 322 box hooked up too on the same rig, (and it happily sees the 148 bird!). Just a shame it won't authorise the channels I'm paying for - Dish is sendng me a new 322 box!!
Guess the thing to figure out is what is different between users.
If you see the 148 sat, do you have DishPro LNBs? What Switch (if any) and MORE important... what software version are you running?? Do you allow automatic updates?
So here goes with mine...
DishPro LNB's (one twin on 500, one dual on Dish 300)
DP34 switch
811 s/w version 2.63 (I'll have to verify this later today!)
Automatic updates allowed.
Many we can find a common denominator?
I think the S/w version is more likely the culprit (maybe there's a bug with switch types and how it handles them). I very much doubt hardware... or it wouldn't work at all... there's only one cable into the box and for the most part it works!
Cheers,
