Hi there.
I recently transferred from Sky Fibre to BT Infinity. Everything was fine on Sky and faster once on BT for the first couple of weeks but lately we have been barely able to browse the web let alone stream YouTube, Netflix etc.
After doing a bit of investigating and logging into my Home Hub 5 at http://192.168.1.254/
I was very surprised to see that all my neighbour's devices were connected to my Router. I know this because they have named their phone's with their actual names and their iMac was connected (I don't have one).
Not only that, a little while later when I tried logging into my Home Hub 5 again, I connected to my neighbour's router instead!! I know this because they are also on BT and they have a Home Hub 4 and that is what it said at the top of the screen.
It's been mentioned to me that it could be to do with homeplugs and I know my neighbours have them as do I.
This morning, I unplugged all my homeplugs and logged successfully into my Home Hub 5 via direct Ethernet connection. All my neighbours devices were still showing as connected.
Then I tried logging in wirelessly. I connected to my neighbour's Home hub 4 this time!!! I though I must have somehow connected to their router but upon checking my Home Hub I was definitely connected to my HomeHub's SSID.
I can try these tests at different times of the day both wirelessly or via Ethnet (homeplugs or not) and will sometimes connect successfully to my hub and other times my neighbour's.
Can anyone make head nor tail of this because some of this seems impossible to me. I have read that it's possible for homeplugs to cross over to a neighbour's connection but how can I be shown as connecting to my neighbour's home hub when I am definitely connected to mine.
Any help with this is greatly appreciated!

Change the SSID of your router, change the network name of your Homeplugs, and configure secure encryption (and passwords) on both. That should do the trick.

And do it with a different SSID for both 2.4G and 5G just to be sure...

That's a *terrible* feature! Microsoft at it again...

Microsoft at it again... Aided and abetted by the US government, no doubt. No wonder they're keen to roll out Windows 10 to as many people as possible.

How can that be relevant?
Microsoft do not control the Home Hub which is where the "connections" are being seen.
Many routers provide a list of the local WiFi networks, are we sure that what is being seen are just that and NOT anything connected to the Hub?
Surely to connect to each others routers would require everyone to be running without any Wap key.

Very true. But whereas I can see my neighbours routers (if their SSID is displayed on), I can't see each individual device connected to them. To do that I would have to be logged in to the router itself.
Simple way round though, just change the SSID and password. And then set up access i.e. only the allowed mac numbers (the OP devices) to connect. Sorted.
Of course it doesn't explain why the problem is happening in the first place - unless BT only have a couple of default passwords....one reason to ALWAYS change them from the default.
As for the Microsoft password sharing feature with Windows 10...words fail me.

could be the windows 10 password sharing feature
http://www.cnet.com/uk/how-to/how-to-kill-wi-fi-pass...
While I do not agree with this password sharing of Windows 10, it would not be that as the OP said a Imac and mobile phones was connected, so unless the Imac is using Windows 10 and the phones are Windows phones then that is not possible.
I also can not see how homeplugs can connect either as they have to be synced with each other to start with and surely the houses would be on two different circuits, also the mobile phones would not connect to homeplugs unless next door have a Wi-fi extender.

No, as I'm connected to my Router's main SSID (the one I made up) not the secondary one for BT customers who are roaming.
|
|

Just randomly managed to connect to my Home Hub 5. All my neighbours devices are connected to it again via ethernet

Err, that would require a lot of long leads .......
Take a screenshot of what you are seeing.
Park the image somewhere like DropBox or a photo site and post a link so we can see what is going on.

Either they have sneaked a cable in or it is a HomePlug issue.
You need to talk to your neighbours and work with them to isolate both sets of HomePlugs and WiFi. If they have no technical understanding - do it for them.
Also, is it possible to ban specific MAC addresses from the HH5? Some routers have that capability - if so, bar all of your neighbours from your hub and likewise, bar all of yours from theirs.

Yep, that looks like a home plug wi-fi extender problem, maybe you should try and reset your home plugs and sync them again.

It's the powerline adapters, they are horrible things.
Effectively, thanks to the powerline adapters, you have an ethernet cable between your Homehub and his.
When anyone connects via ethernet, or wireless, or powerline, to either homehub, the device requests an IP address.
Given that there are two DHCP servers (the homehubs) on this one connected network, it's pot luck which one gives out the IP address. So, you can connect to your wireless, and get an IP from his router, or vice versa.
The router's "connected devices" page is not live, it is a list of devices to which it has given IP addresses. If these devices are disconnected, they won't immediately vanish from this list all the time - although wireless devices might - so you can't use this as 100% accurate.
Note that it says his iPhone is connected via ethernet. Obviously this is not the case, it is connected to HIS router's SSID, but YOUR router gave it an IP via DHCP. As far as your router is concerned, this connection came via the ethernet port so that's where it's listed.
The solution is to remove the homeplugs, and burn them on a bonfire. If you really like them, perhaps change the encryption on them.
If you unplug the homeplugs, don't expect all his stuff to vanish from the router's list immediately.

You do know that you'd need a full hard reset of the Hub to completely wipe it's memory of what has been previously connected .....

I suppose on the positive side, such a feature might make "plausible deniability" a rather more likely to succeed in legal cases such as copyright infringement (or worse).
However, I'd agree. Allowing automatic sharing of password information without the owners explicit authorisation is shocking and, I'd have thought, possibly illegal.
|

As it says in the screenshot, Access Control 'disabled'. Enable it and configure what YOU want to connect to YOUR router. Blacklist everything else, job done. It really is that simple to cure.
|
|
|
|
The networks need to be broken - just blacklisting won't stop the OPs devices connecting to the "other" network. The powerline adapters need to be properly secured so that they are on a different network than the neighbours. As it stands everything on both networks can see each other (or would take minimal change to allow them to).
|
|
|
HomePlug units can vary their encryption either by pressing a button on the allowed devices in a short time frame or using the built in software to talk to your own plugs.
Doing that should stop them being able to hop onto the LAN running over the HomePlugs

Indeed - and that is what the OP needs to do - they don't need to blacklist or change settings on the router they just need to break the link with the neighbours power line.
Personally once the link is broken I would also be changing the passwords on the router as it is possible the neighbour could have got hold of those - unlikely but may as well be safe.
Personally when I used homeplugs I set my own secure password on them rather than using the buttons to do the auto encryption - that way I had control and I like to have control over my network.

The other issue will be that they will be "interfering" with each other and thus restricting the bandwidth on each network. Easy enough to sort out the LAN connection issues, but little can be done to stop the interference.
I wonder how close the power networks are. They would need to be on the same phase and be connected very close to the metering point which itself would need to be close to the CUs.

First configure access control.
Go to settings and access control, enable access control, then block each device between 02.00 and 01.30. This will get your bandwidth back quickly.
I use this feature to control when my kids can use the internet on each device. Helps them sleep when they cannot be on the internet after 10pm and get their homework done if I can block games devices at certain times.!
If you go to advanced settings and look at Home network you can see all devices that have been connected, if you refresh you will just get all those connected at that point in time.
You should also change the password on your hub to prevent other people accessing it and changing the settings.
You can then reset the homeplugs following the Homeplug instructions so that only yours are linked. ( Different sets have slightly different ways to change the encryption on them).

I disagree. Fix the homeplugs - the access control is irrelevant as if they aren't on the network then they won't be using bandwidth.

i am still surprised that home plugs can go from one house to the next.

I'm not, if they are on the same supply circuit. What I am surprised is how weak the security is when using them out of the box.

It does suggest they are using the same key from the factory. I am not surprised that 2 devices in the same package have the same key but more surprised potentially that all devices have the same default key (or all devices from the same manufacturer).
I suspect now that all devices are configured the same when they leave the factory so if you pick up several different sets of powerline devices they will connect straight away without any configuration - that is a definite security hole (partially mitigated by the fact they don't cross phases so the number of people on the same "electrical circuit" would be limited.

I have been in this house from new, for 47 years.
it is the western-most one of a terrace of four, with the sub-station clearly to the east, about 200 Metres.
I recently obtained the local distribution map from the electricity supplier; and was surprised that it clearly showed the supply going from the common footpath, in to the immediately adjacent house, say #2, then back out again to my house, say #1.
Speaking to the "neighbour" in #4 at the other end, he was aware that his supply similarly went in to #3, to come out again to his house, #4.
Several years back, he had a problem; and like myself, thought that his supply came "straight"; but the repairing electrician after checking Fuseboard etc in his #4, said that he would have to go in to #3, as #4's supply came via that - thus effectively confirming the similar diversion for my house.
Good thing that #3 neighbour was at home that evening!
The only reason I can think of, was to avoid having some form of jointing box/es in the footpath.

Many years back, my late brother obtained some form of early baby monitor, which plugged in to the mains within the house.
The battery-operated receiver would pick up the RF signal by a simple aerial, close to a mains socket within the house, something along the lines of the Home Plugs, although not exactly the same.
Experimentally, I took it out to the street; and could pick up the signal clearly at several of the lamp posts.

Those original ones were well known for the range and lack of security. There were stories a the time of people listening in and hearing the "nocturnal activities" of neighbours several houses away.

As were the early Cordless Phones, especially if listening with a SW Receiver!

I'm not, if they are on the same supply circuit. What I am surprised is how weak the security is when using them out of the box.
If the fuseboxes have wire fuses, transmission between adjacent circuits and premises is very probable. Some electronic circuit breakers can stop transmission between circuits. In one site I have tested with electronic circuit breakers, homeplugs cannot transmit from one room to the next - because they are on different circuits.
If the fuses are a Wylex wire type they can be replaced easily with electronic ones that simply push in.
