Powerline Network Extension

DanielT used Ask the Experts™
Anyone know if Powerline Network products can be used to extend a network as detailed further below?

I have a few situations where wireless is not a good option and have been interested in the newer 500MB Powerline options (ie D-Link). I know the 'standard' powerline products require a device at the source (router) and then one for each connected device but what I would like is to simply connect two network segments using powerline devices.

ie: Network segment 1 TO hub/switch TO Powerline adapter TO Powerline adapter TO hub/switch TO Network segment 2

- Distance is max 200-250ft
- Throughput requirements not high; only need to provide internet to a max of 3-4 light usage systems
- Connection to same electrical circuit is available

Any ideas or help on this?

yes, they can be used in this manner.  in some of my customer's larger houses, we use a network extender over powerlines to add a wireless access point on the far side of the house.  Side one goes into a power outlet near the swith and is connected via patch cord.  Side two goes into a power outlet near the location of the wireless access point and is connected via a patch cord.

if you want to try it on the cheap, buy these from staples:  http://www.staples.com/Netgear-85-MBPS-Powerline-Network-Adapter-Kit/product_782582?cmArea=SEARCH


Interesting. The reason I posted was due to D-Link telling me that the devices will not work in the configuration suggested - thus my posting for others' experience.

You mentioned NetGear but the device seems to be much slower at 85MB vs newer units at 200/500MB. Any experience with these?

Well you need to make sure the Powerline units are tied to the same circuit breaker panel.  I have had trouble using Powerline units with different breaker panels.  Make sure not to use a surge strip it will weaken the signal.  Another thing to check, is check how many devices you have plugged into the wall plugs.  The more devices plugged the more resistance you will have degrading your Powerline network.

I think I need to clarify my last post in regards to "devices will not work in the configuration..."

Specifically, I was told that these devices would support a connection such as a PC but would not support a hub/switch. Not sure how this can be or if it affects only the newer, faster powerline units. I would have expected to be able to connect a hub/switch as easily as a PC. Anyone know if the faster devices do or do not work with a hub on "receiving" end, so to speak?

I am familiar with the other limitations such as being on same power circuit, sharing of bandwidth, poor performance when electrical noise exists etc.
In my opinion, the tech support you spoke with didn't know what they were talking about.

There is really no difference between what they told you, and saying you can't use the ethernet adapter in your computer plugged into a hub/switch (good luck finding an actual 100Mb/s "hub" by the way... you might find one that's advertised as a hub, but I'll bet you it's really a switch).

Check out this kit from Newegg - http://www.newegg.com/Product/Product.aspx?Item=N82E16833122329
One end of it IS a 4-port switch.

And this one, http://www.newegg.com/Product/Product.aspx?Item=N82E16833109038 - which says "Compatible with all Routers & Gateways" right in its description.

Both of those kits use 200Mbps adapters.  I believe you'll find that the manufacturers add the duplex speeds together to come up with the claimed speeds for the ads.
e.g. 200Mbps means they should approach regular 100Mb speeds (100 send + 100 recv = 200Mbps, in their minds).

I have a NetGear Powerline device plugged into a switch and I am sharing that connection to a PC, Freesat box and X-Box 360?

Netgear have the XAVB1004 which includes a switch - specifically for extending the network to a number of devices - I believe this uses the slower 100 Mbps service.

Their newly introduced XAVB5004 Bridge is a 500 Mbps solution with 4 port switch.






Thanks for all the input. It would seem that D-Link is not currently a good choice as there are others that will support the desired configuration whereas they say it won't. I will look further into one of the solutions provided (most likely Netgear) and will close the question. Thanks!


Thanks again for input. Will most likely pursue NetGear XAVB5004 as an option.
