If your modem stops working and I cannot email you, then I cannot contact you without exposing myself to non-ionizing radiation from a cell phone. I have been diagnosed as having electromagnetic hypersensitivity (EHS) by  a MD and need to prevent exposure to cellphones, WiFis, and Bluetooth devices.

I advise you to choose cable modems such as SB8200, SB6190, T25, S33 etc. Because they only support hardwired connections and do not support Wi-Fi.
