Netgear r6400
Why can I not get speeds of 400 mbps? I can get it hardwired to modem. When I try through netgear router I can only get 200 mbps. Tried a reset after version update. Still only 200 mbps. Help would be...
I don't really know what brand it is. It just says spectrum on it. It was exchanged. Before this one I had an Arris modem from spectrum. This has happened with both modems. I think it has to do something with the router itself. Don't know if a old firmware update affected it or a setting. I don't know off a setting that would throttle how fast data runs through a port.
Did you ever try a factory reset?
If not, do a factory reset.
During the reinstall, make sure to leave qos, access control, traffic monitoring, and parental controls all disabled.
reason why is those services disable cut through forwarding (ctf). Ctf is needed for those older/base model devices to hit gigabit speeds. When ctf is disabled, the processor has to do traffic inspection and it doesn't have the cpu to manage much past that 200mbps.
Usually you can just disable those services and ctf gets re-enabled. But i have seen instances where it doesn't and a full factory reset is needed to re-enable it.
- Thanks. Did a factory reset a bunch of times before making this post. No luck.
Did you do a fresh install? By fresh I mean making sure not to use a backup configuration. Test if with everything in the default settings and see what speeds you get. If you get full speeds, then start customizing/testing and see at what point it drops the speeds
