re: Slow Internet Problems

I had this EXACT same issue this week. I plugged in thee routers and two computers DiRECTLY to the modem and only one computer would get an IP address (get to the internet). That modem needs to be replaced.

Now as far as speeds spectrum only guarantees 500mbps in your case to the modem. So once you get it working go to Speedtest.net from a wired Ethernet connection to the modem. Everything else is on you past that point.
