My daughter has Spectrum 400 internet and I setup her Tivo and mini about 8 years ago using MOCA and put a filter at the entry point in the cable box outside. Last week her internet was down and I stopped by and checked the Modem and router and doing speed test I would get about 4mb only. I checked all cables and went outside and saw the filter so I removed it and internet was back to 400mb. Today I passed by to install a new MOCA filter that I had and the internet went back to 4mb. I removed it and back to 400mb. Do you think Spectrum made a change that the filter can cause a problem.
