Bandwidth needed to stream internally

Hi

Daft question probably but I want to stream downloaded content from my vero 4k+ to another TV. Both devices are hardwired using homeplugs, but I can only consistently stream low bit rate webrips without it buffering. My internet is quite crap , about 18 meg, is it dependent on that ?

Cheers

As in network over “the power cables”? That’s the issue in my mind, they are so dependent on the copper that was never graded for digital signaling. And as I understod it, can have issues with interference from source you would never consider.

I have Tp-cable cat. 5e to places in my apartment where, due to building code there is a lot of metal nets in the walls, wifi is wonky. Since the apartment complex was built in the early 70’s the power-grid in the apartment isn’t even grounded, just in the bath room and kitchen. When they renovated the bathroom a few years ago, and put in a plug for a washingmachine, they had to hunt the whole apartment for a grounding socket, which was placed behind the wallpaper in a hidden compartment in the living room, like 1,4 m above the floor.

Your internet speed as such wouldn’t have any influence on how fast one device on the LAN can pull data from another device on the LAN. But as Joakim says, if you’re running network data through electrical cables, that certainly will limit the local network speed, and might well be what’s causing the problem.

Thanks for the responses. I did intially try it via wifi but buffering was far worse. TBH I’ve never had any issues with homeplugs and they seemed to provide good throughput.

I did the test from pc hardwired (with homeplugs):

Well their throughput depends on the interference at the time. As you can see in your results they currently are basically unusable with a throughput below 10 MBit.
You can try to unplug and re-pair them for better results but I would wonder if you could get acceptable throughput

Yep, good idea but speed was pretty much the same so guess , it must be the wiring in the house.

I do have 2x 1gb/s adapters on router & vero, and 1x600m/bs on the other PC but guess as the speeds between the 2 are no where near that, there’s no point buying another gigabit one to try :frowning:

Well normally you only can expect 30 - 35% of the advertised bandwidth. Means the 1GB would do 300Mbit while the 600Mbit ones should do 180Mbit in ideal situation. But I never got more than 10% out of them.

Did you just go with wifi extenders then?
I do already have one but as you saw, the speeds were even worse.
At a bit of a loss now, as just got new media room set up but can’t stream to it from main living room. We are supposed to be gettung ultrafast BB soonish - might that help?

They are as painful as they share the wifi bandwidth unless you have an expensive dual radio one.
Best is always a cable to then connect an additional AP.

My home network was composed of powerplug (Devolo) for years, let’s say 10. Even for OSMC streaming. With time I learned the best place to place them and of course best is to have 2 nodes on the same power line. Then each connected gear on this line can affect the signal, reason why some models have a power plug on the back (filtering).
Also do not mix the version (HomeplugAV1 and HomeplugAV2 for example).

It seems the new mesh wifi systems (Asus XT8, Netgear Orbi, etc.) may be an alternative for people not able to wire. My own tests of such reveal very good performances if you have enough nodes to cover properly your place.

Cheers. Did wonder about the homeplugs with the socket on - will see if that makes a discernable difference.

I can’t see anything on the plugs to suggest what version they are - they’re all 3+ years old - would that make them v1?

Will have a poke around re AP/ and mesh as they may be an option if I can get them cheap enough.

@pinn73 Your internet connection has nothing to do with internal transport speeds, apart from the router your ISP provides you with. It can provide crap WiFi, most likely due to lack of powerful antennas, or the inability to properly align the antennas (like the Huawei POS I was stuck with). :frowning:

To be fair, looking at the process of elimination it might be cheapest to get 1 or 2 UTP cables first and hook up the vero and tv directly to the router, test what throughput you get there, before buying other devices, etc.

@fzinken Could it be that your “10%” would be the Megabit (Mb) to MegaByte (MB) conversion? Ideally this would be a 1:8 ratio (1 byte = 8 bit), but I agree that using 1:10 for math will put you on the safe side.

Very pleased with my prosumer network :smiley:

No, I just was referring to powerline adapters. The max you can get is 30-35% in Mbit (as even TP Link writes in below FAQ). But even 30-35% is not real. 10-20% is more realistic in MBit. So if the package says 1Gbit you can be happy if you get 200Mbit out of a powerline adapter.
Notthing to do with Mbit to Mbyte conversion.

So it seems the wiring was at fault there and I have got a bit of a speed boost, but still no where near enough to stream 4k to the other room. I can’t run a lan cable in between easily as they are other sides of the house.

Unfortunately, not. It’s an old house

Those are some pretty grim WiFi speeds. I get anything up to 200Mb/s over 5GHz WiFi.

Depending on how much money you want to spend, you could look into something like buying multiple Asus routers and setting them up with AIMesh.

Wiring up the house for wired Ethernet is a pain in the bum, but you only have to do it once. You can route cables along the top of skirting boards, over the top of doorways, through walls, even under the floorboards to get across a hallway if necessary. Ethernet cables can be very long - cat6a cables, for example, can reliably send 10Gigabit signals through a cable 100m long, and there are several specification levels above that if you really want to go nuts.

You usually only need one long cable leading from the router to each room/area, then a local Ethernet switch in the room itself.

Agreed. Although they are through an extender as can’t pick up wifi otherwise in the other room I want to use.

Ethernet may be the way to go as guess I could route it outside, along the wall to hide it. I only need it for my TV set up in the other room so seems overkill, but seems it may be the only option open to me.

One more test result. Moved my PC to the same room where router and vero are. vero is connected to router directly and PC on wireless network, not via extender. Progressively better but it seems to be a combination of crap router (technicolour) plus dodgy wiring for homeplugs.

Is the option then to replace the router with something and see what increases I get from that?
