I installed three EERO pro units in one place and in late Winter, I noticed that the network was offline, but the client hadn't called, so I figured he hadn't been there since it's their lake house. He contacted me about his outdoor TV and Roku problems, so I went there and asked about the EERO- turns out that the cable guy was there to fix the problems which were in the cable feed from the curb. HE told the homeowner that EERO isn't good stuff and he should get something else. It had worked fine for 1-1/2 years- I beg to differ.
