Hi! 

I am struggling with an issue that I see that others have, too. In sum, my download speeds are fine but my upload speeds are nearly half of what they should be. I know that the issue is not with the ISP. I have confirmed this by directly connecting to the ONT, where I get symmetric download/upload speeds (around 950mbs). I have also confirmed this with a Verizon technician.

Below I outline my setup and some troubleshooting I have already undertaken.

Setup:

Fios ONT -> ER707 -> Computer

The ONT is connected to the 2.5G WAN 1 port. The Computer is connected to the 2.5G LAN 2 port. 

In this setup, I get approximately 900mbs download and 300 upload speeds.

I have tried the following steps:

  1. Checked cabling. All are Cat. 6. All verified working. 

  2. Enabled/ Disabled Flow Control

  3. Explicitly set the negotiation modes

  4. Verified that IPS/IDS is not enabled

  5. Cycled power

When I connect my ONT to WAN 3, which is 1G, and my computer to 2.5G LAN 2, everything seems to work! I get symmetric upload and download speeds (at or near 1g). What is going on?

Why does 2.5G WAN 1 port seem to limit my upload speeds?

**EDIT**

I should have mentioned the ONT is a Nokia I-211M-L. Since this model only has a 1000Mbps data port, do you think it is possible there is an incompatability issue/ bottleneck with the 2.5G WAN? I assumed that the WAN port would negotiate down to 1000Mbps (according to the orange light, it does). I even explicitily set the negotiation mode. Perhaps therein lies the issue?

** EDIT 2 **

 

Okay, I am fairly certain that there is a bottleneck issue between the ONT and the router, when connected to the 2.5G WAN 1 port. I put a small, unmanaged 1Gbps switch between the router and ONT (ONT -> Switch -> 2.5G WAN 1). Immediate got symmetic upload and download speeds. 

 

My tentative conclusion is that the ONT has issues negotiating with the router. Very much interested in any one elses thoughts.
