We are only using wifi in the house from a cable modem through a wireless router. The modem was connected via 2 three way splitters and an electronic booster far from the modem connection. I want to connect the modem at the entry point before the splitters and after the booster. Can too strong a signal damage the modem?
Not damage it but it might not work or not work well. Also a amp can amplify the noise in the line, making the signal worse even though the signal is stronger. Post the signal levels from 192.168.100.1 for review.
It would also may help to know the model. We had a tech insert an Antronix MRA2-11 at the ingress, only for cable, and when he put it in he stated you "must never put it in series with a modem". That doesn't agree with the specs, but given that it is specified as +11.5 db nominal gain and my signal is already at about +14 (until I padded it down as an experiment) I suspect it was good guidance. Since I no longer use Cox Cable, the downfeed from the antenna in the attic now goes to it, and then it goes to the legacy cable feeds in the house.
