Gigabit speed being throttled down
So we have 1000mbps internet plan with Comcast Xfinity. Modem - Netgear Nighthawk CM1200 Cable Modem Router - Netgear Nighthawk XR700 Pro Gaming Router Both are up to date with Firmware Connect...
If you're having the issue on multiple routers, then it tends to point at either the line coming in, the modem, or some way you're setting up the routers.
Comcast technicians aren't the best for phone support. they're main goal is to get you off the line.
Do you have a screen snip of all your modem connections info? This can help a lot. As well as the logs.
If you have any splitter, attenuators, amplifiers in line, I'd recommend removing them. Preferably, I'd also recommend moving the modem to right where the coax enters the home. If that isn't possible, inspect the line for any damage, kinks, cheap/poor connectors, loose connectors, etc. Even small things can cause issues when you're running gigabit.
You've put that its happening every 1-3 hours roughly. If you hardwire into your modem for that period, what speeds do you get?
Are you using any port aggregation features?
Same issue. After reboot, 1000Mbps down and 40Mbps up. 3 hours later, like clockwork, drops to 20-30Mbps down and 20-30Mbps up. Signal strength is fine. I do have link aggregation enabled - which is why I got this modem/router combo. Did anybody get this resolved??
Yes, disable LAG.
The CM1200 is NOT a modem/router combo. Its only a rmodem.
