I'm only 10.5K feet from the CO, and after 3 modems, cant keep a connection. I would always have to power cycle the modem.
Tech support is terrible.
Expect 20 minutes minimum to 1hr for tech support that will tell you to call someone else. It was always someone else problem. I'm still trying to get a refund and get it off my bill. I would cancel Verizon all together if I could get another Telco. Cable modem has been great.
