Dropouts

I am constantly getting this error msg on my network log. When I do a check via my hub 5 it says I have home WiFi problems. My devices are in the same room as the router. Keep getting dropouts while streaming.

RNG-RSP CCAP Commanded Power in Excess of 6 dB Below the Value Corresponding to the Top of the DRW;CM-MAC=**:**:**:**:**:**;CMTS-MAC=**:**:**:**:**:**;CM-QOS=1.1;CM-VER=3.1;

I've done research on this group as to fixes but all saying an engineer needs to come out.

Thanks
