goCoax MoCA 2.5 adapter

[krkaufman]

In my setup, I only have D-Ext enabled, and the phy rate has always been above 3000.

Sounds right, since that should get all 5 possible channels bonded.

The prior post was trying to address the question of how to configure a goCoax adapter to coexist in a DOCSIS 3.1 environment, where D3.1 “initial rollout” signals are present within the 1125-1218 MHz range of MoCA Extended Band D. The MoCA spec doc suggests that 4 channels should be available for bonding in such a situation, shifting the low end of the MoCA range to 1275 MHz, capping max shared throughput to 1600 Mbps (2000 Mbps TURBO) — 400 Mbps per channel (500 Mbps TURBO).

New goCoax MA2500D adapter (MoCA 2.5 w/ 2.5GbE port) has been released.

Quick Question, regarding the goCoax 2.5 adapter.

I see there is a LAN led light as one of the three lights. What does that led indicate?

I ask because I am seeing some strange differences on that light.
Example:
I use a UDM (base) as my router. When I plug the Coax into port 2, the led is mostly off and sometimes blinks on. I dont believe the port is bad on the UDM, cause I have connected other devices to that, and it works just fine.
When I plug the Coax into anything other port, the led is pretty much always on (barely can see it blink).

So, I am just not sure what the status of that led indicates.

Thanks in advance

Typically the LAN led is for the ethernet port, not for the coax port.

Hi guys, I got a pair of the MA2500D and they are working fine for the most part but initially I was seeing strange issues such as not being able to get to local computers and local websites not loading. It turned out it was because my whole network is jumbo frames (9K) enabled. I had to disable jumbo frames to get things working on both sides of the coax bridge. Is this expected behavior or should the MA2500D support jumbo frames?

Well the "target" NIC is the same for both tests and connects through my ER-X router (which has the WIFI AP connect to it so that can't be the bottleneck.
I tried connecting the laptop directly into the router and here is what I get:

did you ever solve this.. im having a simliar issue phy rates are fine all 3500 or so but i get faster single stream iperfs and real world outside speedtests when i connect to a good old 1gbe switch.. when connected to my trendnet 2.5gb or 10gb and even tried 10gb sfp+ signle stream reates are lower.

as you multiple streams can hit the 2gb limit. but i need fast single stream as using as a backchannel from upstairs to downstairs wifi..

if necesasry i can get other switches if i know one that works?
