Review on π Efficient High-Speed Internet Connectivity with Motorola Surfboard SB6121 Cable Modem by Jesse Spoja
No longer supported by Xfinity/Comcast in 2020
I've been using this modem for a year with no problems. I moved a few blocks and kept my xfinity service but was told it was no longer supported. I'm not sure how it worked properly and only now that I've moved is it suddenly unsupported. I wouldn't buy this. Check with your service provider to see if this works with their services, and ask if there are any plans to phase out older models like this.
