TWC customers and Engineers are reporting back my previous posts on good connections have resolved almost all drop outs on 217, and others. Even though the picture is digital, it is still transported as RF over the cable system, and our frequency on TWC is very vulnerable to common RF issues.
Make sure all cable is RG-6 or better. Make sure every connection is clean and tight, by looking for shiny center conductors, and good crimps on the connectors. Poor crimps or too tightly crimped connectors are the most common fault because at these bitrates, it acts more like waveguide than cable. Any splitters or amps in the system should be checked since each connection can have a 3dB drop in signal strength, and amps can amplify more noise than signal. The more direct connection the better.
Keep in mind your home builder may have put (cheap) wires in the walls instead of a qualified installer. If all this fails, and using a little patience, TWC can help you test signal strength using channel 999 and determine if your signal is borderline, and send someone out to help.
