Netgear AX3000 / RAX40 detects lower bandwidth than link actually provides
My home is on Verizon FiOS with 400mbps up/down. I have an Ethernet line running from the ONT to my router, and the router backfeeds all of the coax in the house through a MoCA adapter. If I connect ...
Update: I tried a lot of stuff. I tried updating the installing the initial release of router firmware and updated through every release that Netgear had provided. No luck. I tried unplugging the ONT BBU and disconnecting the battery terminal -- didn't help. I spent a long time contemplating the graveyard of ISP equipment and the labyrinth of coax splitters they had mounted. I chatted with Verizon support: "Your router, your problem." No help here. No matter what I did, the WAN statistics in the admin interface read 100M (Full).
I had figured that autonegotiation was failing (the WAN port itself was immaculate), but I didn't know how to verify that (those logs aren't visible) nor test it. In the end "WAN capped at 100ms" was the magic search-engine phrase to find the solution. SNB forums provided the solution -- stick a dumb switch between the ONT and the router. The ONT negotiates with the switch, the switch negotiates with the router, et voilà. Speed's up to scratch.

Hi Christian,
Thanks for reaching out. Although I don't know why Ethernet autonegotiation failed, I managed to resolve my issue by adding a switch between my router and ONT. I did try reaching out to support, but my support period had lapsed. The shortest (read: cheapest) support subscription is half the price of the router, so I think I'll eat the cost of a switch instead of doing a deep dive on autonegotiation. Cheers.
