Powerline networking?


[link to this post]
 
Hi, apologies if this has been answered before - I have looked and couldn't find anything about it.

We're (Wandsworth - LSWAN) due to go FTTC in March. My master socket is under the stairs, together with two 13 amp power sockets. Is there any reason why the supplied modem under the stairs should not be connected to my router (in the study) via a pair of powerline plugs (I have a pair of Devolo dLAN Duos). This would seem to be a more elegant solution than having a cable wandering halfway round the house.

Due to IP addresses I'm not sure. I use the a set of Devolo's myself. The way I have it set up is that I have the modem and router plugged into the master socket and plug an Ethernet cable from my router into my Devolo device and have the other devolo device upstairs. Works a treat wink

Following on from lee111s, what speed rating are your Devolos, and what is your FTTC speed estimate? Recommended checker.

The Duo are the old blue 85Meg units, that is 85/2 and then remove overheads, so are not really man enough for FTTC.

The AV200 at a minimum, but with speed upgrades already due the AV 500 really should be looked at.

Notwithstanding the speed issue, my gut feeling is that this would not work and lee111s's solution would be the more conventional approach.

The Homeplugs don't usually appear as IP devices, i.e. they are just dumb bridges so should work between modem and router.

That's interesting, because mine appear as IP devices.

Agreed, they should work fine to bridge this connection.

I have a set of D-Link AV200 units, they report a sync rate of 185Mbps to one another (one is on the upstairs ring, the other on the downstairs). I figure that provides plenty of overhead for an 80/20Mbps connection.

Previously I had a set of the Belkin gigabit powerline adapters, which rarely synced above 100Mbps before they died. Despite a lifetime warranty I abandoned them: life is too short!

You need to ignore the sync rate. I never really worked out the relationship between that and real throughput. For a start you probably only have a fast ethernet (100Mbps) connection in them. I think the 200 figure is the theoretical combined duplex speed.

In my experience with Devolo kit you'll be doing well to get much more than 40Mbps real throughput on 200Mbps spec.

My experience with the Devolo 200Mbps connecting to each other at approx 100Mbps gave a throughput of just under 30Mbps.
