R6700v3 unable to support 400Mbps - capped at 140Mbps
My R6700v3 seems to have the internet downlink capped at around 140Mbps. I upgraded to 400 Mbps service but was unable to get the connection speeds. A tecnician from the ISP came to take a look and switched out routers to show that the modem was not the issue and even direct connected to my PC and I am getting speeds over 400Mbps even when using the R6700 my connection is capped at around 140Mbps. The technician said that the R6700 was know to not support the higher speed internet, but I cannot find anything in the specifications that would indicate that wired connections would be limited.
Can anyone confirm whether the R6700v3 should be able to support 400 Mbps, or do I need to get a replacement router.
I couldn't wait anymore, kicked the family off the internet...and...Success!!! After a factory reset, and a little waiting, I'm still on Firmware version V1.0.3.66_10.0.50, and using Speedtest my download speed is 947Mbps! This is great! Going to test my other wired devices to make sure all is good there, and then I'm done for now!
I'm hoping that Netgear sees this post, and start looking into a fix to resolve the issue with the new firmware. I'd love to be back on the newest firmware version.

the R6700 supports gigabit speeds. The cable guy wasn't giving you good info. I specifically don't have an R6700 but I've hit gigabit with an R6300. so it brings you to troubleshooting.
1. how are you testing the speeds? Wifi isn't a reliable way. Make sure you are hardwired into the router and try more than one device if you have it. also make sure you are using a decent quality cable.
2. You state you can pull the full speeds if you're wired into the modem. What modem is it?
3. Firmware on the router?
4. whenever you update services, I always start with a factory reset. It removes any qos settings or other settings that could be slowing you down. You can do a bunch a troubleshooting, but sometimes its faster/simpler to start from factory.
Here's the support site for the R6700. It'll have your most recent firmware, an install guide (in case you do factory reset it), and a manual
1. I have a cat 6 cable connected from my pc to the router (no wifi involved)
The cable guy had a Netgear 1900 with him, he unplugged the R6700 and replaced it with the 1900 using all my cables exactly as my set up and we were testing using speedtest.net with his router we were getting 450Mbps with 22Mbps uplink (ish), when switching back to my router it immediately dropped to 140down/22up ish.
2. The modem was supplied by Charter Spectrum and is a Arris D3.1 WIRED EMTA (no markings on it that comes from an email)
3. Firmware is latest V1.0.4.78_10.0.55
4. There are no QOS settings enabled in any of the settings pages, but I have not done a factory reset, just a hard power off.
here's what I'd try.
1. power off the modem.
2. Factory reset the router. Start fresh.
3. Setup your router with modem off. when you've done your basic setup, save a copy of the configuration in case you have to reset it in the future.
4. power off the router.
5. power on modem for a couple minutes. Let it fully boot and get up and running.
6. then power up the router. give it a couple minutes to fully boot. log into gui to make sure its connected to internet properly.
7. then speedtest.
8. if still getting lower speeds, try replacing the cable between router and modem. Still low? try replacing cable between router and computer.
did it work?
