MoCA speeds slow

Splitter to MoCA

Make sure splitter is wide-band and not standard (most splitters don't pass above 1GHz, below where MoCA works).

Posted

Hey all, I recently bought a pair of actiontec MoCA 2.5 boxes on amazon to save the hassle of running Ethernet across my house.

The fist box goes coax outlet

Splitter to MoCA then Modem (netgear CM1150V)

I have the Ethernet connection to the lower box connected to my router (R7000-100NAS) as that was the only way for the MoCA devices to actually work.

While running internet speed tests I average lower speeds connected via ethernet from the box than WiFI across my house. Averaged around 130/35 with MoCA and 250/30 via Wifi.

 

Any clues as to why the speeds are so lackluster?

P.s

I connected the modem in my desired room and got roughly 850/50 so I know the coax lines are good. still short of the gigabyte goal. but better.

Yes, MoCA relies entirely on the quality of the Coax in your home including noise, interference and splitters.

 

Only way to test if the devices themselves are working well is with a short coax between them and testing as shown here. Good watch either way for setup tips.

Directly from Actiontec's site for the devices you bought:

 

Quote

*Actual speeds will vary depending on the condition and noise found on the coaxial wiring. 1 Gbps is the maximum throughput to end devices. The maximum throughput over the MoCA network is up to 2.5 Gbps.

** Theoretical data throughput numbers are based on maximum, theoretical PHY throughput for MoCA 2.5. Actual throughput will vary based on the condition and noise found on the coaxial cabling within the home as well as the type of Ethernet Adapter supported on each computer or other device.

The info should be on a label on the splitter. Also make sure its a decent quality splitter and not a cheap POS. 

I just want to sit back and watch the world burn.

Got a wide-band splitter and speeds are now up to 850/40. Thanks for the help.
