NETGEAR CM500-1AZNAS (16x4) DOCSIS 3.0 Cable Modem only provides 38Mbps vs. cable modem's 150Mbps. Specs for the Netgear say up to 620Mbps. The upload speed is 5.7 which equals the cable modem. There are no adjustments in the modem.

It has lower throughput than your cable modem and so since there are no adjustments, all you can do is upgrade the firmware and test and if that does not help then get a faster box

Talk to your internet provider. Does your ISP allow you to use your own equipment rather than what it supplies? Most don’t, so it’s possible that you’re fortunate to have a connection at all.

Comcast supports it. It activates through their portal.
The specs say:
"CableLabs® DOCSIS® 3.0 certified to work with U.S. cable Internet providers like XFINITY® from Comcast, Spectrum, Cox, Cablevision & more (not compatible with Cable bundled voice services)"
I have a router. There is no way to update the firmware on the device. Netgear says the ISP will update it but, comcast won't update a 3rd party box. Basically, it just doesn't perform as advertised.
I was speculating, however, that it is in the cable company's best interest to "accidentally" throttle 3rd part devices. <g>
