I'm having an issue with the @RDk-3036 error on my small X1 box. I changed my service to the X1 boxes and self-installed them last January, and until about a month ago I had no issues. But now unless it's a cool day, I'm getting the RDK-3036 error every day during the day, and the warmer the day, the longer the error lasts. I suspect that as the weather gets warmer the signal loss in the cables increases. And I know my current setup is not ideal--I have a 10dB amplifier where the cable comes into the house, a splitter at the output for the modem and the TV, and a second splitter for the main and small X1 boxes. Problem is there are some long runs involved, at least 30 feet from the first splitter to the second, and a comparable amount from the second splitter to the small X1 box. Before X1, I could use a second amplifier to boost the signal to the old small box, but I learned when I installed the new boxes that with X1, the two boxes need a direct connection between them so I had to remove the amplifier.
I'm thinking that I need a different amplifier and/or spilitter where the signal comes into the house. But I can't take time off work to have a tech come out and look at everything--I've seen from these posts that they can be there for hours--I missed 6 weeks of work because I contracted the virus (that's how I found out the error happens during the day). Is there any equipment Comcast could send me that might solve the problem? When they reopen, I do have an Xfinity store very close to home, so I could easily return anything that doesn't work.
