The modem is uBee Ambit U10C018 DOCSIS 2.0 Cable Modem (https://www.amazon.com/formerly-Ambit-U10C018-DOCSIS-Cable/dp/B0088R1P06)
I have the cheapest Spectrum connection, download runs at about 3.5 Mbps and upload never more than 1.25 Mbps.

That is the only reason I am setting up the home WiFi. The next higher tier connection from my ISP is $30/month more...
