    Needed a good replacement for my previous Surfboard modem. I use Spectrum cable service and this unit is on their approved list. I had no issues connecting the modem to Spectrum, did need to call them to complete the setup but not hard. I am consistently getting about 12-15mbps over my paid service of 100mbps.
