How to have several identical wireless doorbells respond to the same code?

[Rob Morley]

Yes it does.

[MM]

You're wrong. I get exactly the same performance whether My PC is connected directly to the D-Link switch with a CAT6 cable or via a TP-Link plug on the mains. Around 6.9 Mbps on ADSL.

[Mike Clarke]

But that's being limited by the speed of your outgoing broadband connection.

What speed do you get between two devices on your side of the router using the TP-Link plug compared to the CAT6 cable?

[Huge]

You're killfiled. My experience might be different to yours. But I am not "wrong".

I hit upon a brainwave this morning! I simply stuck the chimer in my trouser pocket. So no matter where I am, even in the garage or garden, I cannot fail to hear it. The chimer unit is extremely lightweight and after a while you're no longer aware of it. A refinement would be to dismantle it and put the gubbins in an even smaller container.

[MM]

Well, of course!

You mean, if I'm copying a file from one PC to another across my home network?

MM

[MM]

Ooh, that hurt!

Your comment was: "Ethernet over mains sucks syphilitic donkey dick."

Not: "Huge's Ethernet over mains sucks syphilitic donkey dick."

Too much generalisation is not helping!

Never? Ever?

I just have the door alarm sound in every room. And in the garden.

[dennis]

So it doesn't suck if you aren't really using it?

How fast does it do a network backup to a NAS?

Mine does >600Mb/s over WiFi.

[dennis]

huge dick is always wrong. Except about DIY as he never answers a DIY question.

[dennis]

My battery chime comes with a belt clip so you can carry it about. The mains one could have a clip but I think my UPS is a bit heavy.

This could well be the same sort of argument as the 'get you home' puncture 'repair' latex foam sprays and the pre-puncture gels that provide an instant and permanent solution? Chalk and cheese.

I have used Powerline adaptors in many locations (typically TP-Link brand) and have had no issues with them whatsoever.

The last instance was a NowTV box across the width of a lounge > hall when run over WiFi it was constantly buffering and hesitating. Plug in a pair of TP-Link PL adaptors and it's been fine ever since?

At the same site they also use a third TP-Link PL adaptor to put WiFi at the back of the house and a 4th to connect a PC in the upstairs study.

None of the people there are 'technical' and so I would be the first person to hear if there were any issues ... and I haven't.

This experience is repeated in every location I've used or recommended PL as a solution, where there were no real / reliable alternatives.

Now, would I guarantee that you would always get the same bandwidth as a good Cat5e cable, no, because for 'most people' that's rarely (if ever) a requirement.

Would I guarantee that there is no RF noise generated in those locations? No, I wouldn't, because again that's never been an issue that has been raised so I've not had to deal with it.

Am I saying I would recommend PL over traditional bounded Ethernet? Well, that all depends on the location and the willingness of the people to rip up flooring or run cables over the surface versus using a PL solution (that 'works' AFA they are concerned).

He is clearly wrong in this instance as there are millions of people using them every day and with no issues.

Now, if we start to drill down into the specific situation where people have had issues or not found them to be as good as other solutions then that's different.

I was asked to provide Internet access for a family friend who lived in a large house that was originally two houses that had been joined together. The issues was the two building parts were on two CU's and so PL wouldn't work without 'bridging' the two CU's. So, I used PL to get a WiFi signal as near as I could to the remote PC and then WiFi to do the last bit. Once setup, there were no other issues. Was it 'fast', no, but it was faster than their Broadband at the time and so that was all that really mattered.

As mentioned elsewhere, anyone who doesn't find something works well

*for them* might suggest that in their statements or state under what circumstances it didn't work for them or why they may *prefer* something else.

Few would argue that bounded Ethernet isn't going to be the *best* solution but that's only going to be the case if the user is willing or able to run such cable though their building.

I ran some Thin Ethernet in Heathrow T4 and they needed a specific (Belden) cable (I think) that had a secondary foil screen because of the high levels of RF / Radar that was about. Had I not used the 'right cable' I could easily say that 'Thin Ethernet sucked' when it was clearly the result of the location. The fully loaded 8 port Thin Ethernet repeater I installed at a previous job never had any issues at all using standard RG-58C/U.

They may well be as fast as a slow or medium Internet connection, but they are unlikely to be as fast as even WiFi, let alone Gigabit ethernet for local network transfers. And, of course, they are fundamentally antisocial in causing widespread local interference at HF. I wouldn't use them for the same reason I wouldn't play loud music at 2 am or pour oil down the drains. It's simply bad behaviour, even when legal.

[Mike Clarke]

[T i m]

I would argue that point, especially when you are using WiFi in a new build with foil backed plasterboard etc.

Yes, great, *if* you can get some cable in there. Many (many) people can't or won't so then what?

They tested those at a RW 115Gb/s (FWIW).

Do you have any information to support that assertion and that covers all makes and models?

Are we talking *all* PLA's or just bad / faulty ones?

And how many people actually listen to shortwave these days. ;-)

Cheers, T i m

[Bob Eager]

However, others might have had issues with the RF interference caused by your solution!

[Roger Hayter]

Since they work by injecting HF signals into the public power network, I should say all of them. Some notch amateur bands successully, but amateur radio isn't the only thing on HF.

So a minority not deserving of protection?

[T i m]

I thought they wouldn't typically pass *out* of your private power network, especially though the RCD etc in the CU, certainly not with any signal strength?

I know they don't work on filtered multiway sockets or even a basic (non filtered) one if it's on a long lead?

Ok.

Well, as a 'radio amateur' I have been told it's 'use it or lose it'?

So, what about all the other causes of electrical interference mentioned on the link?

"Control Equipment Domestic Electric Cables High Voltage Power Cables Industrial Scientific Medical Equipment IT Equipment IT Power Supply Unit Lighting Power Line Adaptor Power Supply Unit Battery Charger Security Equipment Transformer TV Aerial Amplifier TV Equipment"

OOI, I have assisted 3 people who were suffering with poor WiFi signals around their houses (using WiSpy WiFi 2.4Ghz frequency scanner).

One turned out to be rouge remote speakers on a HiFi system, another one of those 'TV-Senders' and a 3rd a car alarm (the problem was only there when the car was parked on the drive). ;-)
