Powerline - slloooowww

[Peter Cashen]

Hi All,

I've posted in the relevant IT techy forums... I'm one myself, but got no answers.

Basically just moved into a new build (no Ethernet wiring unfortunately), but was going to use powerline adapters.

In my old house they worked fine and I'd get 150mb/s or more, but in this house they wont go over 70mb/s, so thinking that it must be to do with the electrics or RCD things.. I know nothing about electrics. Is this a known issue? Anything I can do/try?

Hi Peter and welcome to the Forum !
The starting place for me would be - what speed has BT (?) provided to my house? There should be a service test point - unplug any house wiring, measure from there and report back
Edit : as it may only be 70Mbps (you lucky person ...)

Is this a local LAN / ethernet? I'd start by getting the earthing tested and check for a neutral-earth voltage that shouldn't be there.

Hi.. sorry, missed that out.

Its Virgin... if I connect directly to the router then I get 225mb/s! I'm on the fastest BB.

Ok, this is what I was hoping for... I've no idea what this means... I'm an IT guy, and I've exhausted my IT technicalities! So it must be electrical...

How would I test this?

I would try to narrow it down, so try both adapters on the same circuit close together first. I.e same room as your router.

I'm presuming this is transfer speeds as you stated 150 mb/s.

Hi,

So far I've literally had the two adapters in the same double socket with the laptop and router next to one another... no difference, still only around 30% of the expected speed.

I've also turned everything else off in the house to prevent interference/noise - no difference.

This is why I think its to do with the core wiring/electrical system.

 

[LeeH]

If you have them in the same double socket it's not the fixed wiring.

Reset both back to factory, check firmware, try a hammer.

Same router?

Try a different Ethernet cable?

I thought all you IT guys do is turn things off/on again.

I'd be running some data cable out.
I have tried a few different plug in adapters and they all start out good but all have dipped in speeds over time and eventually given up.

I think @Marvo hit the nail on the head there.

If they are in the same socket, does that mean that everything is done within that socket and nothing goes near the RCDs or fusebox thing??

Both have been reset. Even tried a different pair and same issue.

Tried multiple cables.

I've ruled out router - definitely either plugs or core electrics.

Hammer isn't far off.

In my old house definitely.

In this new 3 month old house - the wife would kill me. Ha.

@Andy78 I've had good success, I wired a garage 120m away from the residence, it synced fast enough to browse/ YouTube etc.

I use them at home extensively as all my walls are solid so wifi drops out very quickly.

225 megs a second....Jesus.... are you serious? I don't think our national backbone network runs at that speed. I just upgraded to 2 meg ADSL at home and that took some pulling of strings.

Unless you have serious noise on the line then yes I would say it rules out the fixed wiring.

What adapters are they?
