Powerline networking

I'm trying to extend my cellular hotspot to an outlying building about 130-150' from my house. Thought of an extender setup of some kind, but someone suggested I look in to "powerline networking".

Not familiar with it, though reading about it, it sounds intriguing. My power comes from the pole to a main breaker box in my house. The power supply to the outbuilding is on that main line. From my main breaker box, the various circuits are distributed to my house circuits with a dedicated "branch" circuit going to a second breaker box with breakers/circuits for the outbuilding itself, and my pumphouse.

So, is that considered to be "all on the same circuit" and doable for this type of setup? If so, could I "hardwire" my cell modem to the house circuit using a powerline device plugged in to a house outlet and an ethernet cable from my cell hotspot, then use a second device (and ethernet cable) in my outbuilding plugged into an outlet and attached with it's own wireless access point/device to deliver wi-fi there?

The phase of the 220 mains. This varies with country but there's a 50-50 chance it's fine. If not try a plug that the breaker is on the other side of the main panel breaker box.

Could you expand a bit?

Not exactly sure what you're saying here when you refer to "220 mains". I'm not a electrician, and am in the US, if that makes any difference. All plugs are "downstream" of the main circuit breaker box.

Like I said, my hotspot is in my main house, and I'd be plugging into a standard 110 outlet on my kitchen "lighting" circuit (where my cell hotspot is plugged in) which is 20 amp.

The outbuilding service branches from my main power service at my house box on dual 125 breakers (250 amp total?). The actual physical lines traverse through my foundation and then underground to a second breaker box located close to the outbuilding, where another set of breakers distribute to circuits in my pumphouse and cabin. I'd be plugging into a 20 amp circuit in the cabin for the second powerline device/ethernet connection to a wifi hotspot.

My thinking is that because all the wiring shares a common point (the circuit breaker/service box in the main house), it should work.

The 110 is one side to the 220 mains feed to the home.

In reply to: Could you expand a bit?

If you look at the circuit panel 99% of the homes have rows of breakers left and right. That's often called a "side." I'm an electronics designer so to me that's called the phase of the 220 feed.

You'll catch on. But if your house and barn is on that same circuit it works. There's a kit to bridge the two if need be. Would be installed by the electrician. Most folk just try other plugs.

Got it (I think)

In reply to: The 110 is one side to the 220 mains feed to the home.

I've got two sets of breakers, left vertical row and right vertical row. The breaker(s) for the outbuilding circuit/main is at the top of the right row. So, if I read you right, I should be able to plug into an outlet on another circuit on the "right row" for the main house for it to work since both would be on the same side/phase. Thanks, I'll give it a go as soon as I get my "powerline network" devices.

That's correct.

In case you're interested...

The powerline solution worked. Slight degradation of up/down speeds, but very acceptable.

Thanks for your insights. Happy

Thanks for the report.

As to slowdown, any time we stick something in the path, we lose a little speed.

Powerline is usually our best shot at solving situations like yours.
