MoCA Network Setup | Ethernet over TV cable

[manyu882]

Another point. My router default gateway is 192.168.50.1

So the MoCA default address when connected directly with a PC via ethernet is 192.168.254.254

I went into the MoCA admin page under static IP, should I change it to be similar to my router subnet (e.g. 192.168.50.88) ?

Hi all, just got my goCoax units. Setup was ok and was blazing fast compared with my homeplug.

However, I'm faced with intermittent internet loss. It was ok for few minutes and down for 1-2 minutes and repeat again. Seems like they are catching a breath.

Anybody encounter such issues ? I checked that internet is ok with main router.

1) Did the Coax LED light blink/Change colour?

2) Check the RX and TX table and also the Attenuation graph when it is disconnected. Did you find anything amissed?

This kind of symptom is likely to be a faulty unit and it happened to me once before.

 

[manyu882]

Abit confused.
Won't the signal leak to elsewhere since there is no PoE filter at the main SCV splitter ?

POE Filter is required for most angmoh countries is because their splitter is rated 5-2300mhz pass.

For SG, so far all the units I see here uses 5-1000mhz pass splitter. Xiaofu99 pryed open and posted a few photos of the splitters earlier.

MoCA Band D ext. uses 1125-1675mhz freq range, which is outside the pass band. Therefore, theoretically, signals should not leak out.

Asking for clarification since MoCA can use freq above 1000mhz, if there are splitters installed downstream means Band D freq unable to be utilised?

I'm not quite sure of the question in relation of the picture.
Possible for signal in Band E and F to leak since splitter/POE passband is 5-1000mhz? Anybody can explain further?

If it is manually set at band E and F, then signal can pass through. auto by default it uses D extend.

Thanks a lot

Mine is also the same as XiaoFu99, utility box locked outside of the house.

I followed XiaoFu99 and pried open the box.

My sharing with goCoax 2.5 MoCA adapter

Ordering

Ordered 2x goCoax Moca 2.5 coaxial to Ethernet converter (model: WF-803M) @ USD 59.99 each and a POE filter @ USD 7.80. Shipment cost will be another USD 22. Total USD 149.78.

Order placed on 24th May, shipped out from China, Kunshan @ 26th May via SF Express. The parcel was delivered to my place @ 29th May.

What’s in the box?

In the box, it contained the unit, LAN cable, quick-start guide, 12V/0.5A adapter with US prong and a UK plug converter! That was a pleasant surprise to include a UK plug converter. Do note that no coaxial cable is included in the box.

Existing Setup

M1 500Mbps fibre -> Asus RT-AX58U router -> Aztech 500Mbps Homeplug -> Aztech 500Mbps Homeplug in my room -> PC (via LAN cable)

Below is the speed test result (on the high side -> usually around 140~170).

goCoax initial setup

The setup is pretty much the same as existing (see above) with the exception of replacing homeplug with goCoax adapter and data going through the coaxial network instead of electrical wiring.

At this moment, the coaxial cable/splitter arrangement at the electrical riser box remain untouched.

A LAN cable is connected directly to the goCoax unit in my room. On my desktop network settings, disable auto DHCP and manually assigned 192.168.254.10 IP address. Thereafter, from the browser, hit 192.168.254.254 to access the admin page of the unit.

It was loaded with FW v1.06 which is the latest as per shown at the goCoax support website. On the setup page, configured the security by choosing a 12~17 digits for the MPS (MoCA protected setup) as well as changing the admin login password.

Below is a screenshot of the link speed between the 2 units.

With such a link speed, the speed test result is more than 2x of my existing setup with homeplug!

The excitement was short lived. Even though the speed enhancement was tremendous, however, the internet suffered from intermittent disconnection (e.g. resolving host).

For every 5 mins or so, it will be down like 2~3 mins and recovered by itself. The cycle just repeat itself and become much more severe if you are downloading at high speed (e.g. 40+MB/s from rapidgator).


Troubleshooting

Perform a direct connection between both units of goCoax using ~1m long RG6 coaxial cable to narrow down cable, unit or setup issue.
With such a connection, the link speed increases by ~2x as shown below.

After testing for 3hrs or so, no internet disconnection was observed. Thus, it came to my conclusion that the cable/splitter maybe an issue.

I went to the electrical riser box and decided that both the living room and bed room coaxial point should reside in the same splitter. By using trial and error approach to identify the cable, finally, I managed to get both points to connect at the same splitter. Similarly, I also removed the white cable which is supposed to be the incoming signal from Starhub and replaced it with a POE (Point of Entry) filter which I got it from goCoax as well.

Does POE filter matter? Not sure and no quantitative number to back it up. However, I read from the MoCA installation document, it recommended to install a POE filter to reflect the signal back to home network which helps to increase the signal level.

Below is the final setup at the electrical riser box.

And below is the link speed after performing the changes at the electrical riser box. The link speed is almost close to the direct connection.

My final configuration:

M1 500Mbps fibre -> Asus RT-AX58U router -> goCoax -> goCoax in my room -> TP-Link Archer C7 configured as Wireless AP -> PC (via LAN cable)

Speed test from the above configuration:

Tested more than 6hrs with no internet disconnection observed.

goCoax and Amazon also out of stock. Maybe you drop gocoax an email via their support page to enquire about it. So far, they are pretty responsive.

Besides Gocoax, there are few selling MoCA 2.5 adapters on amazon.com and other websites.

[On Amazon.com] Kiwee Moca 2.5 adapter - Manufactures from Yitong. It uses Maxlinear Chip, which is basically the same as Gocoax.

[On Amazon.com, but is sold out] Luster Moca 2.5 adapters - It also using Maxlinear Chip that is same as GoCoax. One thing good is that they have dual Lan Ports

Hitron MoCA 2.5 Adapters. It also using Maxlinear Chip that is same as GoCoax


If your speed limit is 1Gbps, then bonded moca 2.0 adapter will meet your requirement. I'm selling to international customers, sending from China as well. Have local warranty. If does not work for you, can return with a small restocking fee. PM me.

 

[syihabuddin]

Yes. There's a guy here selling his no longer used set. I didnt see his PM and already bought from Gocoax Amazon. I can pass you his contact number.

A good alternative to MoCA? Although it says its using G.hn technology, it doesn't run via powerline like traditional homeplugs - it uses Coaxial very much like MoCA too.

Saw the reviews and it looks workable alternative considering gocoax is so hard to get nowadays?

G.hn tech for coaxial over ethernet uses 86mhz frequency(if i recall correctly). if you get them, you have to disconnect the splitter or install a low pass POE filter because almost all the splitters installed in singapore is rated 5-1000mhz pass.

somemore Low frequency signals can broadcast very far due to minimal loss

Minor correction.
Homeplug AV uses 86MHz.

G.hn uses 100MHz band to get 1Gbps or 200MHz band to get 1.7Gbps.

It is said real world performance MOCA >G.hn > Homeplug.

From the reviews Homeplug AV2000 never really get above 400Mbps, G.hn Wave 2 1200Mbps gets around 600Mbps over coaxial and Moca 2.0 gets around 850Mbps.

Thanks for the insight ... i guess G.hn coaxial is the next best option since Gocoax's stock availability isn't stable or unknown availability.

So if its in 100Mhz, the current splitters will still work right? I can safely still unplug the SCV incoming cable without plugging in a POE filter yeah?

If you can unplug the SCV incoming cable, then you should be fine.

The performance of Comtrend GCA-6000KIT seems to be pretty good at close to 600Mbps speed.

Edit to add:
Of course you can get much better speed from Moca 2.5 (dual gigabit type of performance) based on the the previously shared Lon.TV review of GoCoax Moca 2.5 adapter.

The Homeplug AV2000 is kind of laughing stock if you compare the real world 100-400Mbps speed versus the advertised 2000Mbps speed. But on the other hand it is really convenient and 100Mbps is really good enough for many things like 4k streaming.
