Netgear’s tech support is the worst.
My recent experience with this Netgear CM2500 has been terrible. I bought this model to replace my CM600, which had no problem for 6 years, but I upgraded my ISP’s plan to 1000 MBPS, which CM600 does not support. The product I received is defective and the internet speed will drop from 900+ MBPS to 1-3 MBPS for no obvious reason. Once it drops, I unplug and replug the power cord, the problem goes away. I have been communicating with Netgear customer support for the past 2 months and could not get a replacement. There were several technicians asking me to do the unplug and replug power cycle. I told them the problem will go away immediately, but will come back the next day. Then they keep me checking different settings. After they could not fix the problem. Netgear switch to a different technician and start over again. Now, they say it is Xfinity’s problem again. I had Xfinity come and already checked. I had no issue for the past 12 years for the same ISP with no issue. I am sick after 20+ hours with Netgear tech support for the same problem. For my experience, if the Netgear product is non-defective, it works for many years. If the product is defective, Netgear’s support is like hell.

A good direct “pass thru” cable modem so far.
Initial setup needs a direct LAN connection to a computer. Likely anyone who has setup a modem separate from a modem-router already knows this. The web interface is great and worth exploring the advanced options.That’s it…happy networking!

Easy to set up, works as described.
I purchased this Netgear modem to avoid renting Xfinity equipment. After the modem arrived quickly, I connected this device to the internet via coaxial cable (not included) and called Xfinity to activate my internet. After a few mins, I was able to get direct online by connecting the modem to my computer via ethernet. Lastly, I purchased (separately) a WiFi mesh network that I connected to the modem to get wireless internet.
