The past couple of months, I've been having trouble with my Bolt either having break-ups or no signal on some channels. The signal on our cable modem and the Bolt were apparently pretty weak, so they sent out a guy. The Spectrum (né TWC) guy came out and spent a couple hours here doing some rewiring, removed one splitter, added another, moved stuff around, added a different splitter, and then set things up so that the Bolt and ran off of a splitter and not daisy-chained from the tuning adapter. This worked for a while, but then channels started breaking up again. During this time, I gleaned that apparently the Bolts are known for having a more sensitive tuner than many devices, and while for most things they work in a ±7 dB range, the Bolt apparently works in a ±3 dB range. I spent this past weekend trying out a few more things: At their advice, I swapped the tuning adapter ("Those have a lifetime of 5 years and you've had yours the better part of a decade")... no difference.. then I called back and was told to try swapping the cable card. (No, another hour in the car + 15 minutes waiting in line). Since the guy on the phone with the tuning adapter and cable card swaps both said I had plenty strong signal, I though it might be too strong for the Bolt. I went on Amazon, found a "3 dB coax attenuator" for $6 shipped, put it between the Tivo and the first coax, and viola!, my channels are clear again. ... I still might drop Cable after this though. Probably the last straw.... ... BUT, if you're having trouble, consider both too strong AND too weak a signal as possible problems.
