Ridiculously Slow Internet Speed
I'm paying for 300mbps and using a Netgear CM1000 modem and Netgear nighthawk router. My Wifi speed 15 feed away fromthe modem is averaging under 5-10 mbps.
I have called Xfinity technical support multiple times. The agents perform standard troubleshooting such as reboot of modem, router and blames Netgear modem/router. They sent tech support engineer and he checked a couple of spots and said I'm getting a good signal and left.
I have spoken to Netgear customer support and they point to internet service provider (Xfinity).
How do I make sure that the line coming into my house has a highspeed throughput before it hits my modem to isolate these issues?
