Heres a beauty.
Got Optik a week ago, continually losing signal ( error code on screen). Happens on more than 1 TV at the same time, so eliminates interior wiring. Replaced PVR as it showed error codes + Gateway (modem). Problem still exists. Checked light ( fiber connection ) it is fine. You can start an on demand TV show ( Street Outlaws, on 2 TV's at the same time........they quit within 40 minutes....same test with 3 additional on demand shows, same results. . I do have 2 switches in the network, but neither on a TV having this problem
I did read on the forums to reboot equipment in order of Gateway ( modem) - PVR - any wifi boosters- any other STB's in that order. Still no change
So its not PVR / Modem / wiring / fiber.....
Live TV Fine / Internet Fine / PVR fine......On Demand....not so fine. I am stumped
