Networking In-House to "Man-Shed"

[frase]

I have a client whom has a Router Inside a Tp-Link something has Three Antennas so should be high gain. They purchased it from elsewhere

So the client wants to be able to connect to the TV outside which has Wifi/Wired ability. They purchased the TP-Link POE device from elsewhere - Think is this model 450Mbps High Power Wireless N RouterTL-WR941H


The setup is as follows -

• Router Inside Home
  
• This is using wifi
• Also Using a POE device to connect to other device (TV) in Lounge for Netflix etc

This is all working fine even on a powerboard.

Though if I tried to connect another TP-Link POE to the same board.
Then Connect the other Device outside directing into a Power Point then ethernet to TV, I get no Connection.
It also stuffs up the other network inside.

Could it be conflicting IP address? Maybe try to connect device which is routing to the outside shed directly into a PowerPoint?

I dunno I am fine with local networks in the one area, though when it comes to long range networking I am a total noob.

What would anyone suggest here. I was thinking of a Range extender like a Ubiquity nanobeam or Litebeam. Though I have no Idea how they work or how to install them.

So you have a TV successfully connecting to the LAN via powerline adaptors (also called homeplugs), you now want to add a second TV (in outside shed) also using powerline adaptors, but when you try, it brings your whole network down. Do I have that right?

Yes that is correct

It sounds like there is a misnomer here. TP-Link powerline units are not POE but homeplug. The only time I have ever seen what you are describing is when two master units get plugged in at the same time instead of one master and multiple slaves. Any possibility you confused the units? Also - Did you pair the new slave correctly to the master? (Test it independently?)

Point of clarification in agreement with those that posted before me. Power over Ethernet (PoE) is not Ethernet over Powerline, also known as Powerline Ethernet. Homeplug is a subset of the former.

And yes, it sounds like the procedure for pairing the new powerline device wasn't performed. There is encryption involved, they're sort of like bluetooth devices, you have to get sync them up before they work.

The other thing about networking over power is that it has to be the same circuit. An outdoor shed is often on a separate line. Can’t network that together.

 

[Sky-Knight]

@nlinecomputers No it doesn't, but I'm not sure what the demarcation point is. I have a separated garage here, and I can connect to a circuit here inside my office, have it bounce through the breaker panel, and out to the sub panel in my garage, and to the tool bench. It's slow, and there are frame loss issues just like in my living room, but it does work.

but I'm not sure what the demarcation point is.

common ground. It's not the same circuit if you have a separate ground.

common ground. It's not the same circuit if you have a separate ground.

And yet, my garage is a separate building with its own grounding spike.

But, it is an older home that doesn't have isolated ground, my neutrals and grounds are on the same bus bar in both breaker panels. So perhaps that's how that's working? The 100amp feed to the main house is bonded to the house via the neutral.

I've found that powerline adaptors can be a bit hit-and-miss where you're dealing with discrete circuits. Performance can range anywhere from good down to zero. If you're sure everything is paired up properly and you've ruled out faulty units, I'd probably try one of the following:

Run exterior grade ethernet cable from the router to the shed
Mount an exterior grade PoE access point on the house exterior, such that the shed is within its range and cable to your router
As above, but use something like Ubiquiti nanostation to set up a wireless bridge between house and shed

 

[nlinecomputers]

But, it is an older home that doesn't have isolated ground

That’s a common ground. They both are grounded to the same Circuit.

 

[Sky-Knight]

That’s a common ground. They both are grounded to the same Circuit.

Yes, in the main panel. But I have a sub panel in the garage with its own grounding spike.

Which means the union between the house and the garage now has two paths to ground, which as I understand it... is bad. I have some reading to do, because now I'm curious.

Not being narky but I didn't need a lesson in perfect description of name of the device's. I was after a solution or suggestions. They are on the same circuit & have been paired correctly.

Cabling is to costly for client, as they are selling up soon. Though due to COVID-19 they cant due to real estates being closed.
