Speeds drop when connected directly to internet

[tcooper]

I have CL Fiber, so there's no need for a modem and the C3000Z they provided is just an bridge, I don't use it, so I thought, I should save 10 bucks a month. Internet is the only service I have, no phone, no TV, just a 940Mbps plan.

So I tried pulling it out of my network, and setting up my Netgear Nighthawk XR1000 in its place. Got my PPPoE credentials, setup bridging on the VR1000 and added a VLAN (id: 201, name: Internet)

Connects just fine when using the incoming line that the C3000Z was previously using... BUT. My speeds are significantly lower. Upload goes from ~900 to 250mb/s Download isn't as drastic, but still looks like a 25% decrease from when I have the XR1000 just hanging off the CL provided router.

Any idea why this would be? Am I being punished and throttled down for removing the C3000Z? Am I missing something with the setup on the XR1000?

Welcome to the forum!

That's interesting, do you still have the same reduced speeds if you put the C3000Z back in place between the XR1000 and the ONT? Can you then configure PPPoE on the C3000Z instead and connect the XR1000 to it via DHCP?

Yes, if I do that, speeds  go back up.   I have not tried setting the C3000Z as a transparent bridge.

So far, I've tried

ONT -> C3000Z acting as the PPPoE client -> XR1000 = fast speeds

ONT -> XR1000 acting as the PPPoE client = reduced speeds  

In the second case the C3000Z is completely out of the network.  The reason I'd like to remove it is it's a rental fee I could not have to pay.

OK thank you, we are aware of this issue and are working to replicate it internally.

A short-term solution for you could be to purchase a cheap router to function as a PPPoE client. Then you can get rid of the C3000Z. In the meantime, we'll get to fixing this issue for the next firmware
