ARRIS SURFboard SB6190 Gigabit+ Cable Modem

I dislike "renting" HW from a internet supplier. In my new place, Xfinity was my only option. While I had problems with Comcast 10+ years ago, with no other options I was hoping things had improved. This modem works exactly as expected. When Xfinity came out to setup my service, the modem came up and I was able to plug in and get internet access with the tech here. Simple. One ethernet port and no Wifi, but a good price. However, I wanted to use my slightly older Netgear Nighthawk D7000 Wifi-Router as my primary connection into the house. It took calls to Netgear, Arris, and Xfinity before I found the right set of steps to get everything working. Not well documented, and none of the helpdesks could do much to get me working. While I reset things so many time across two days, I believe the right steps were: - Arris up and working (can see internet with a hardwired PC) - Cable from Arris to Nighthawk "Internet/Wan" port - Cold boot router - PC to ethernet port on router - Navagate to 192.168.0.1 (Nighthawk admin page) - Netgear Genie comes up, let it do its thing (10+ minutes) I had to have everything up before I could use 192.168.100.1 to get to the arris modem page, but it turned out that this modem is simple enough that the only thing I did when I got there was turned off all the the LEDs (blue and bright). I would hope other routers would come up easier. 5-stars for the modem (after the setup pain). I'm getting full speed and things have been solid.
