I just received an XG1v4 receiver. After taking it out of the box I get error RDK-03004 (trouble communicating with server) After hours on the phone with Comcast and more tests than I can count they are lost. I got into the diagnostic menu and found the DOCSIS signals are reading downstream power -12.5dBmV and SNR 34.9 TenthdBmV. I plugged in another box on this line and it works without issues. Support cannot tell me what the acceptable levels are. From what I understand the range should be +\-15 dBmV I have a +15 dB amp at the demarc, which feeds a 4 way splitter that puts out -7, feeding an 8 tap box that puts out -11. I’ve tried connecting to both and no joy. All other TVs are working fine, and the modem has no issues. Is the XG1v4 extra touchy on signal strength? What is the range it wants? How can I get it there?
