I have a question about diplexing DirecTV and Cable within the same house. Hopefully, someone can help me. I've had DirecTV for 6 years along with Internet access via the cable company. I have the line to one outlet in my house diplexed so that the cable and satellite signals are combined outside the house and then split after they come from the wall outlet. This is so I can have my cable modem and a satellite receiver in the same room. Well, all was fine until yesterday. DirecTV came out to "fix" a problem with my dish. They ended up replacing the LNBs and the multiswitch. The tech said the LNBs were bad, but the multiswitch was fine, but he replaced it anyway because it was old. After that, my cable internet stopped working. The tech and I tried lots of things, but it just seemed like the line wouldn't diplex correctly anymore. The tech called his supervisor. He said they weren't supposed to diplex the lines and they basically said they could create a new outlet for me for the cable or I can take it up with Time Warner Cable. So, I had them create me a separate outlet for the cable. At any rate, has anyone else run into this problem and does it seem like a legitimate issue?
