I added the 4k DVR to my service about 3 weeks ago. It is continously freezing. When it does that it either reboots it self or I have to do it manually. I had 2 tech visits. The first one said it was on the wrong outlet and moved it to the correct outlet. (Outlet . I have another X1 DVR (AX013ANM) on the primary outlet. This did not fix the issue so I had another tech visit. That tech put a MOCa filter on the new dvr which seemed to help at that time. It also stopped the new dvr from causing the other tv's to go offline (which was part of the oriignal issue). He also mentioned to me that our neigborhood had a signal issue because of BGE ( our local utility). He said it had been reported to BGE about a month ago but it had not been fixed yet. All of my services worked great until I added the new dvr. It took the place of an XG2. Luckily I have a ROKU on that TV also, so when the DVR goes out I watch on the Xfinity app on the roku. I will probably call for another tech visit but would welcome any ideas on how to address it.
