Bests & Worsts Reviews from Amazon

Activated on Optimum network in Connecticut. It works great. Replace Optimum offered Arris TM822 which is now charge me monthly fee. After detach the TM822 and attach this SB6183, Optimum network was able to detect this modem right away. However, I had bad experience with Optimum tech to activate/register this modem. Optimum tech claimed that this modem is DOA. (which I don't believe it. I purchased this unit from Amazon brand new.) Next day, I tried myself. (This applies to Optimum Online only. Never tried on other ISP.) I hooked up the coaxial and used the Ethernet cable to connect to laptop. Open the browser and register this modem to the Optimum Online network by myself. You just need your Optimum account and service information. I was able to "Register" this SB6183 less than 5 min and able to get onto Internet through my internal Wireless router fine. In short, this modem works fine with Optimum network, although it is not printed outside the box. Secondly, no need to call Optimum to swap this modem. You can just register this modem by open the browser and look for "Logon to Network icon" from your browser, follow the steps. That is it.
