Tvheadend

I can't help with the bandwidth specifically, but I used to have a Mythtv backend and separate Raspberry Pi frontend. They were split up across my flat and I used Ethernet over power without any problems.

What tv card do you have? I now have OSMC and TVHeadend installed on a single Raspberry Pi so no need to split the front/backend, would this be an alternative option?

Thing is that I have this box in the basement with four tuners a lots of disk....

I have been running OSMC on a Pi with a TVHeadend client for years with an ethernet over power adapter. Ping shows much better latency over this link than I see over wifi.

Are you seeing excessive latency on the power adapter, or sporadic outages?

I would say sporadic outages. Let me doublecheck the setup and manuals.

I successfully use Wifi through one concrete wall for streams up to 15 Mbit/s. You will need a Wifi monitor to find the best channel (1, 6 or 11)

Client: Dual Antenna 2.4 GHz WLAN-N USB Adapter for RPi2/Libreelec (tried 5GHz as well, works also, but less signal strength, less software stability)

Access Points that work rock solid: Dedicated AP like WD My Net N900 or Apple Mac Mini server late 2012

Access Points that did not work reliably: Any Linux/hostapd solution, main internet router providing lots of service at the same time.

OK. I hade a residential ADSL. Connected to that is a NetGear N750 for WiFi. I also have three TP-LINK TL-WPA-4220 powerline adapters. One is connected to the same switch. The other is connected to the PI. The TP Link diag claims the speed is 80Mbps.

There was a setting for QOS, I tried changing that from "Internet" to "Audio/video". Let's see if that makes a difference?

I fear your equipment is underpowered. First of all your router may be a bottleneck. It should have a single core cpu around 500 MHz. I have a dual-core 500 MHz cpu in my router and it can´t reliably stream even lowres TV.

That´s why i opted for a second dedicated Wifi access point on a different channel.

Then a raw powerline link speed of 80 Mbit/s can give you 36 Mbit/s data (45% efficiency) best case, not enough reserve for 15 Mbit/s satellite streams.

I have raw wifi link speeds of 162 Mbps (WD access point) and 217 Mbps (Mac Mini Server) (50% efficiency best case), more than twice your bandwidth.

Yes, but the router is not in the loop here. I stream from a TVHeadend server that is local. Ie when cabled the TVHeadend server and Pi are connected to the same 1Gb switch, but I see your point. If I were to do WiFi to the Pi, then I might need a more powerful Wireless router. FWIW, the streams from DVB-T and DVB-C are not 15Mb/s in my case, more like half of that.

Hi!

I am using 4.0x on a deducated Linux box, with OSMC running on a Raspberry as frontend. problem is that I do not have a wired network connection where the TV sits, so I have been trying various options such as running Ethernet over the TV coax and adapters that run over the power cabling. None of them work reliably though. Occasionally playback freezes and the film exits to the OSMC GUI.

A wired connection always works, but the cable running over the TV-room floor is an eyesore..

Any ideas?

Hallo,

Normally when buying decent HOME-PLUG adaptors this would work. I have never had problems with the ones I have tried. TP-Link and Siemens. I think as others you may have a bottleneck somewhere else.

That is absolutely possible, but where? Ie the other end of that power link adapter is connected to the switch. As such it usually freezes then exits after say 10 minutes of watching. With a cable from the same switch to the Pi, it works. Let me try plugging the "pi end" of the poweline adapter to a extension cord and run directly to the other adapter and see if that makes a difference!

Oh... forgot something....This is essential.

When using these HOME-PLUGS it is essential to get at good quality of network that the HOME-PLUG is plugged directly into the socket. No extending cord or such. If not plugged directly in socket you will/can get problems as described. AND another thing. Once or twice I have discovered bad lan cables. Also check those.

Yes, no extension cords. Another thing is knowing how the house is wired.. I rearranged the boxes and speed jumped up to > 200mbs. Only downside is slightly worse coverage in the kitchen. House is wood and drywall, but the deflector plates under the in-floor heating acts as a shield, unfortunately.

Watched yesterday evening without any interruptions.
