cable box stopped getting connection
TV working fine. Then the next day no connection. followed all the troubleshooting steps nothing fixed. Called for a support technician. Next day he came, replaced the box, still not working. He then told me that i needed to replace all inside cable (RG59) with RG6. I don't understand how suddenly the inside wires are the source of the problem. As my internet is working fine should I just drop cable and go only with streaming services?

Hello, @user_0kz6w9 sorry to hear this unfortunate news. I did some research on this and yes, it is common for RG59 to fail to transmit a stable cable TV signal while still allowing the internet to function. This happens because digital cable TV and high-speed internet use different frequencies, and RG59 handles them with varying degrees of success.
RG59 was the standard cable used for cable television (CATV) for decades before being largely replaced by RG6. While it is still found in many older homes and commercial buildings, it is now considered a legacy cable for this application.
RG59 experiences significantly higher signal loss (attenuation) than RG6, especially over long distances. At 1000 MHz, RG59 loses approximately 12.0 dB per 100 feet, compared to only 7.0 dB for RG6. RG59 does not typically "suddenly" stop working due to age alone, but it often fails to work when you upgrade to modern digital services like high-speed internet or HD cable.
We (e.g., Comcast, Spectrum, Cox) is generally responsible for the "service drop," which is the line running from the street or utility pole to the side of your house. If the RG59 cable is outside and connects to the box on your wall, we'd replace it if it caused service issues. In most cases, any wiring inside the walls of a home or apartment is considered the property and responsibility of the owner.
