Any LAN alternatives other than PowerLine or MOCA?


I've been trying to get a stable connection from my living room to my work room, for almost a year now.

The Wifi repeater[0] I had is too unreliable to deliver anything for very long. The Powerline[1] adapter works for maybe a hot minute and then loses the pairing over the power socket, and now I'm seeing the same with MoCA[2] over coaxial (yes I have PoE filters).

Are there any other alternatives?

whats wrong with Ethernet over cat5?

👤 MainlyMortal
I'm not going to pretend to know a lot about networking but I use Netgear's Orbi routers and receivers. I've tried MANY different router and powerline adapter brands and nothing even comes close. I know it has something to do with using a proprietary communication protocol but it honestly works so well that I just accept it as magic and live my life.

A WiFi signal can improve a lot by changing to a channel that is not as overcrowded. You will likely need a prosumer WiFi device (e.g. Ubiquiti) or then something which supports OpenWRT. Consider also WiFi 6E -- if you carry your signal on a new spectrum then reception likely improves as well.

If cat cable is too thick, there's also the possibility to run SFP fiber instead.

It would help to know more about your home, including the materials and composition of the walls and the general layout. WiFi, powerline and MoCa all failing to perform suggests pathological levels of interference or a problem with your computers. Have you tried stringing a long cat 6 patch cable from one room to the other, just for the sake of experimentation?

👤 anonymousiam
I have the exact same issue. New home with cat6 cabling in every room except my office. I didn't want WiFi (WAP or bridge) because it's in a "smart home" community and there is much interference. I went with MOCA (2.0) because there was a RG6 drop present. You say that you're having problems with your MOCA and that you have "PoE Filters", so I assume you mean something like the ones I use: https://www.amazon.com/gp/product/B00KO5KHSQ

You did not say whether or not you are using the RG6 elsewhere in the house for TV. (I am.) Your RG6 cables probably terminate into a distribution transformer (splitter). I solved the interference problem by installing those filters between the antenna/CATV inputs and the distribution transformer. (If you have a cable modem fed by the same RG6 plant, you CANNOT use the RG6 plant for in-house MOCA.)

Here are some things to check: 1) Make sure you're using RG6 cable everywhere and that there is no RG59 cable being used anywhere.

2) Make sure all the F connectors on your RG6 drops are good. F connectors are generally poor and have a lot of insertion loss. You may need to scrape/sand the center conductor to ensure a good connection because it is sometimes coated/plated with some anti-corrosive. 3) Depending on the brand of MOCA adapter, you may be able to access the (undocumented) user interface by browsing to: http://192.168.1.3

Note that you'll need to change/add the 192.168.1.0/24 subnet to your LAN, and pick a non-conflicting IP address on that subnet in order to connect. Also, all the MOCA adapters have the same fixed IP address, so to connect to each one, you'll need to be on the Ethernet LAN side of the one you wish to communicate with. Once connected, you can see diagnostics with signal levels and a PSD graph that will show you if the frequency response of your RG6 cabling is poor. There may be some settings on the page that will allow you to change the "channel" numbers being used in your MOCA network. The menu on my (ZYXEL) MOCA adapters has a left pane with the following (JavaScript) links:

Device Info

Node Info

Statistics

Configuration

SW Update

The information page for each link loads in the frame to the right of the left pane.

I can't speak to the go coax MoCA adapters, but I have the Motorola MM1025's and they work flawlessly. They are rather difficult to get nowadays, but I hear the MM1000's are just fine as well (just GbE rather than 2.5GbE).

Other than that, you could go for more serious p2p wireless or string a CAT-5/6 cable.

Depending on the layout of your space and how it's constructed, fishing cat 5 through the walls using fish tape might be relatively easy. A quick search will find you guides with the details. However since your place appears to be cursed for networking I'd try running cat5 outside the walls for a while first to make sure it actually behaves as expected.

👤 thefz
Single mode fiber is small, easy to run, insensitive to interference, future proof and... a little bit more expensive than copper. But worth the hassle.

👤 ajonit
Fiber comes to my lower ground floor, from there there are several cat6 that runs across length and breadth of lower ground and ground floor. Provides excellent connectivity across the house. Just ensure there is minimal channel interference across various connected routers.

👤 lowbloodsugar
I paid a guy $2000 to wire the entire house with cat6 and another guy $1000 to redo the walls.

I would imagine a single room is a bit cheaper.


👤 sokoloff
I've had excellent results from both powerline and MoCA in my 100 year old brick and plaster home. Powerline, I was careful to locate the origin node near the service entry and that worked well. (I'm not sure it was needed, but it seemed sensible to not try to locate the origin and the destination nodes both on branch circuits far from the panel.)

MoCA, I'm only using for the TiVos, though I've tapped into it for speed testing when I first installed it and it was "perfectly more than adequate" with no real tuning other installing the MoCA point of entry filter [singular, not plural] (in my case a PCT-VC-F18a) and hooking everything up.

I'm on US powerline, but in case it helps, I'm using the "devolo Magic 2 WiFi next starter kit" for powerline and, once again, that also "just worked".

I'm not surprised you had issues with that wifi repeater. The way those kinds work, they just take an existing wifi signal and repeat it back out. This kills 50% of your bandwidth for devices connected to the repeater. A better option is a mesh network system (like anything on this list https://www.wired.com/story/best-mesh-wifi-routers/). These are much smarter and can tolerate things like a node being taken down, so should work better than that repeater.

👤 tguvot
about moca...

1. replace your ethernet cable to moca adapter. even cable that seemingly ok it still can be faulty. friend of mine had recently similar problem with cable. he replaced $300 worth of equipment before he replaced cable

2. if coax going through splitter and splitter is old, it may cause issues (moca using higher frequency ranges). get new splitter that is moca compatible from reputable company. for example https://a.co/d/0SIcvRP . don't use splitter with more ports than you need and all unused coax connectors should have terminator on them

3. get some coax signal meter to make sure that you have no problems with cable/connectors. in case that wiring is old (>10-15 years), get new connectors and recrimp coax. also replace wallplate couplers (neighbor of mine had problem with moca month ago. i traced it down to bad wallplate couplers. ).

moca adapters can be accessed via browser to see their internal state/quality/etc. take a look at it as well


👤 pelim
did you tried to install a phase coupler for powerline improvement

👤 the_third_wave
Yes, just draw some cat6 between the locations and either connect to it directly/through a switch or hang an access point off the work room end. In the latter case you configure the access point to the same SSID and password/certificate as the one in the living room while using a different set of channels so your equipment will not need to be reconfigured (you may have to manually toggle wifi to get it to connect to the nearest AP since hand-off is not part of the standard). In nearly all cases you'll be able to find some path for the cat6 which makes it close to invisible - ventilation ducts, along central heating pipes, through old conduits meant for copper phone lines, along base boards, etc. Do not use power line conduits for this purpose, that is against a number of regulations and also can cause interference and stray current flows through induction.

Why cat6? Because it is hardly more expensive than cat5 and more future proof. If you don't care about the latter and have some cat5 lying around, by all means use it but if you have to buy the stuff anyway you may as well choose the 'better' option.


👤 beeandapenguin
Depending on how far apart your rooms are, it's not too difficult to wire up a long, flat ribbon ethernet cable[1] between rooms. They usually come with clips to help install it cleanly as a fixture. Then you can just connect it to a separate switch/WiFI access point in the other room and have the same connection speeds. However, if you have two WiFI access points, you'll likely run into radio interference if they don't have mesh capabilities.

I use an 100ft cable to go from living room to basement, and have an mesh AP for each. The Eero devices are relatively affordable compared to Ubiquiti for how powerful they are, if you want a seamless experience using multiple WiFi APs.

You can hook it up directly into your electrical control cabinet.

👤 w0mbat
If you pull new ethernet, make it cat 6 or better. Times change.

I'm not using ethernet beyond the switch room, I threw money at the problem and got a 3 pack of those wi-fi 6 Nest units which form a mesh network. Works fine, covers the house and front and back yards. Costco is selling a 4 pack of those for $450 which is even better. https://www.costco.com/google-nest-wifi-pro,-wi-fi-6e,-4-pac...

It'd be way cheaper to drill some holes and run ethernet in your situation though.


👤 rathleon
Tri-band mesh Wi-Fi routers are great for this. Their dedicated backhaul keeps your own connections stable. Redoing wiring and walls is too complicated and expensive for so little gain in comparison.

👤 supertrope
MoCA is the best alternative to running Cat5 cable.

https://www.duckware.com/tech/wifi-in-the-us.html#improvewif...

Disconnect any extraneous splitters or lines. If the coaxial cable is damaged, has inferior push on connectors, or is RG59 there's a higher risk of issues. GoCoax brand is great so it's probably not a dud unit.

👤 orev
Going to have to go with the others and say that if MoCa isn’t working, there’s a bigger problem (PowerLine is always a bad idea). Make sure:

You have the PoE filter (no “S”, there’s should only be one) installed on the entry point only. Since you said “filterS” it implies you have multiple throughout the network. If so, that’s the cause of your problem as those are designed to prevent MoCa signals from passing through.

Next would be the main splitter. You really should have only one in the house, and it should be good quality and support up to 2500MHz. Bamf makes good ones. It should only have enough taps as cables you need to connect (don’t get a 7-way splitter if you only have 3 cables).

For any unused splitter ports, make sure they are terminated.

Check the connectors on each end of the cables and replace any that are loose or flimsy.

MoCa really does work very well, so I suggest you figure out what the issue is instead of looking for something else. The only thing I can think of as a showstopper is if they nailed through (or stapled too tight) when installing the wires in the walls. That would compromise the cable and there’s not much that will be able to handle that.


👤 Dwedit
I've heard rumors that you can use an adapter to plug Coax into a Wifi antenna port on two different routers, and run "Wifi", but it's actually over a cable rather than airwaves. I have not tested this or verified its effectiveness, or tested if actual wireless devices will see it or not.

👤 djweis
I've used devices like https://www.amazon.com/StarTech-com-110VDSLEXT-Ethernet-Exte... in similar cases. You will likely need to modify your phone lines to get a pair from the living room to the work room, though.

👤 syntaxing
Similar to you, I tried everything, powerline, moca, and wifi. The key is using prosumer stuff. I have a multi story house and a single EAP670 is enough to cover the whole house at 450 mbps+ on wifi 6. It has wifi 6E but only my work laptop has it so I keep it off to save power. I had a U6-pro before that but it would degrade to 200 mbps four floors away. I learned so much I probably can be a network engineer at this point. But I think the lowest friction is to go for Firewalla + a prosumer AP like the two mentioned before. For what it’s worth, I run OPNsense.

👤 loloquwowndueo
Powerline AV2 has been very reliable for me in multiple locations (four houses/apartments in 2 different countries) with both netgear and d-link equipment. If it’s not working for you honestly I’d look at having the house wiring checked because it might well be weird, faulty, improperly grounded, “floated” and a number of other things.

👤 robertheadley
I work for a cable company and even we shy away from Moca if we don't have to use it. The problem with Moca is that we do not control the customers wiring on their side of the demarcation point. Who knows how many Gold Radioshack splitters are in those walls.

We also provide a mesh networking solution from plume and it uses a 5ghz backhaul and does a great job. I would recommend it.


👤 ip26
One clever hack you can use in some homes is to run cat5 in your HVAC ducts.

Even if you can’t direct-connect to the router, perhaps you can move the router a few rooms closer.


👤 more_corn
Most repeaters are garbage from day one. I wouldn’t bother. I also wouldn’t depend on Ethernet over power.

Use a controller that allows for multiple wired base stations.

If you can’t go through a wall with Cat6 you can at least get right up to it and plop a base station right there.

I use Unify gear. The unify dream router and a wired base station near where I want coverage. I have two base stations. My service works great in a big ranch style house (never a single problem). Keep in mind that these routers cast a mushroom shaped beam so place them high and pointed where you want signal.


👤 teeray
VDSL is surprisingly capable, and would certainly work well within a house’s existing wiring (ADSL works over a wet string[0]). I’ve used modules you can buy on Amazon[1] to run private VDSL halfway up a mountain for one client.

👤 badrabbit
You should really make sure thrme ground for your house is in proper condition. The electricity finding other ways to the ground will mess up powerline or moca

👤 firecall
How far is the distance between the rooms?

What’s in the way? Concrete, bricks maybe?

Because modern mesh networks are very reliable.

To troubleshoot it all, I’d get a long run of loose laid Ethernet cable and demonstrate that I can maintain a stable connection to two known good switches on either end.

I’ve been had issues using Powerline, but as others have said, there are perhaps other issues that I’d not been aware of before!

We don’t have MOCA over here in Australia as Coax I. The house isn’t really a thing here!

1. If you don't care too much about it looking pretty ethernet cable can be done with very little effort. I've got an ethernet cable running from a bedroom on the far side of the house (where one of my cable outlets is) to the adjacent laundry room, then down a hall, then into another hall, then into the living room where it comes in diagonally opposite of where I need it, then along two walls to get to where I want it.

Most of this is done on the top of the walls next to the ceiling. I simply screwed in cup hooks every so often and drape the cable over them. Here's a short section to show what that looks like [1]. The other cable in that is a speaker cable heading to my right rear surround sound speaker.

If aesthetics is a concern some sort of conduit or cable tray could be put up there to hide the cable, and probably even be made to look like it is decorative.

2. You might also consider a partial wired solution. See if there is some place you could move your wireless router to that would give a stable connection in your work room and still give stable connections in the other rooms you use wireless from.

Often a poor wireless connection in one room is due to something between that room and wireless router and moving the router over a room or two might fix it.

This is an anecdote but I used to use a variety of powerline adapters to connect my desktop PC to a switch two floors down in the basement of the house I am living in. The house wiring is pretty modern (done in the mid 90s) but I had quite an unstable connection and mixed results with various brands of powerline adapters. I think if the signal has to jump between two breakers in the power panel then you're just going to have a bad time vs if you are on the same loop.

I have used the TP-Links that you had in your pic (or a variation of that model) but I've found that they and all others tend to only last a year before their quality severely degrades. My guess is that extensive usage everyday causes them to endure multiple heat cycles and they just start to degrade in quality of transmission after too many of these cycles.

Despite this being solid state equipment, I swear there must be some component in there that degrades with extensive usage because this phenomenon happened with all powerline devices I've owned.

Furthermore, even before they start to degrade I would lose signal about once ever 2-3 hrs and it would require unplugging one side of the connection and replugging it in.

Over the course of 3 years this also wore out my power outlet(it became much looser)

Like I said, I tried various brands/models. This was because I would replace them once a year. The best experience I had was with TP-Link AV2000 (it had the longest time between disconnects and the best bandwidth)

Before that I used TP-LINK AV500 which I would say is average quality. It was good for the first year but then started to really degrade.

Before this I used Netgear Powerline 500. It was the worst of the bunch, requiring more frequent resets and it too degraded over time as well. I typically find Netgear business class equipment to be great but unfortunately their powerline offerings were a letdown. I dont know if they have improved on this.

Powerline is a fascinating technology and I'm thankful it existed as it got me through 3 years going from poor wifi to finally being able to get a ethernet cable going through the wall.


👤 hdjfkfbfbr
So what about fibre Ethernet ??? You might be able to squeeze a bidirectional fibre (single fibre which uses 2 different frequencies of light for tx/RX) next to your coax runs through your walls? Then all you need is a media converter / switch on both ends...

👤 avidiax
If you have baseboards or carpet, this job becomes much easier.

You can get thin or flat cables that you can just push between the carpet and baseboard. If you have hard floors, you can get a trim crowbar and pull the baseboards off. As long as you are careful, when you replace them and add a bit of caulk, it will look like new. Going around door frames is usually not so difficult: the worst case is that you would need to remove the baseboard from both sides and drill through the floor plate, which will also be invisible after you've finished.

If you have a run that would have to go under carpet, you can use an undercarpet fish tape and some very thick sewing needles to raise the carpet and underpad at any place it is stuck.

If you would have to go through a wall, often there is a cable box in the same section of the wall on both sides. That would let you string a cable between the boxes. In some cases you can add a box without it being obvious. Most corporate landlords aren't going to remember if the 11th layout in their building has an ethernet box in that location.

Sometimes it is just easier to use a preexisting outlet in the wall of outright make a new one. So long as it looks nice and clean no one is going to be upset. And let's be honest. The cost to do this is fractions of a penny compared to contorting around environmental obstacles for shitty gain.

Or you can spend another Hundred hours in search of a subpar solution. How much money has been wasted on doing that? Stop the insanity!
