Broadband/router/hub intraconnection

[#1]

Please help! Customer service can’t figure this out. In December me and my neighbour both got a new router me on plusnet, they on EE. I’ve since had months of dodgy connections, wifi and Ethernet and tv (connected to router via Ethernet). I’ve had three routers in an attempt to fix this. What’s coming to light now is that when I go to the hub to turn my wifi on/off I get linked to the EE hub and my  neighbour is linking to plusnet hub and not EE. He’s resolved by moving his router away from the adjoining wall, but I’m still having issues. Cust. Services also says there were 11 devices linked to my router when I had no devices linked wired or otherwise. I try and run everything on Ethernet and have three tp link adapters around my house, I prefer to have wifi off, and it isn’t a good connection now anyway. This wasn’t the case before we both changed routers. 

tomorrow with the help of a friend I’m going to plug the router into the other phone socket just to see if that makes a difference. It won’t help me as the socket isn’t in my lounge but it’s interesting to see if I can then connect to the Plusnet hub.

today I managed to get the plusnet hub to upload, but when I click on any of the pink boxes to turn off wifi, or change my password, it goes to an EE hub page.

im told there are knowledgeable engineers on here who can maybe resolve the issue.  If that is so, please advise as it’s driving me mad.  I’ve thought to migrate to EE as a provider but what if I do and I have the same problem?

@13 First I've heard of this problem, described like this, anyway. I'm no telecoms engineer, but I'm wondering if this is a 'crossed line', where the connections have been swapped over in the cab?

Hopefully, someone with more knowledge can prove/disprove my theory.

@13 Are your TP Link adaptors Powerline/HomePlug ones? If you and your neighbour both use Powerline adaptors, using the factory default key, and you are on the same phase mains supply it's possible you could be seeing each others LANs?

@13 

This is a typical symptom of two close properties using Powerline devices with default passwords. 

[#5]

Hi when you say default passwords do you mean in the router?

Hi when you say default passwords do you mean in the router hub?

[#7]

@13 No, on the adapters.

No, the password inside the Powerline devices, nothing to do with router passwords or wifi passwords.

Powerline devices all have a password (often its called the "network name" or something like that). If one or more powerline adaptors have the same password then they can all see each other, over the mains wiring.
Out of the box, or after a factory reset, it is a standard name of "HomePlug" if I remember correctly, I've not got mine anymore.
If you and your neighbour share the same mains phase and are near enough, and you are both using the factory standard password, you could see each others network over the mains.

Do you use powerline adaptors?
There might be an app to configure them, or often its done with a button on the adaptor. If you search for the models, you should find instructions on how to reset and re-pair the devices, making them choose a different password from standard (but the same between themselves). You normally have to hold down a button for so many seconds, on one adaptor then within a couple of minutes do the same on the other, and they will pair privately with each other. Then do similar to add a third etc.
They should end up with a different password to your neighbour and you should be okay!

You are looking for the TP PLC Utility

Ah ok. I linked all my adapters when I got them they won’t work otherwise
My neighbour says his are disconnected today and his WiFi had improved.
This doesn’t explain tho why we are getting each others hub and not our own! That happens in Ethernet and in WiFi

[#11]

@13 

You can prove if this is the problern by asking your neighbour to switch off their powerline devices temporarily and seeing if this resolves the issues with your connection (or vice versa).

[#12]

@13 

Our posts crossed, actually it does explain it, you effectively have two routers on the same network. The question is whether you are now picking up your router normally?

Hi Baldrick1

When he unplugged his powerlines it made no difference, BUT when I unplugged all mine, thus working strictly on wifi, i can get onto plusnet hub. So it seems my own plugs were picking up his router somehow. My neighbours move at the end of March whilst the cottage is empty it will be interesting to see what happens. It may not resolve my own problem that my plugs are somehow picking up his hub if that is possible. What I have not yet tried is connecting via my ethernet with the wifi switched off. Thats the next experiment coming up! I dont understand why any of this causes my tv to drop out as it is connected directly to my router with an ethernet cable. This is a tough one for me, as I am not technical!

Now i have cleared browser histories and am working strictly on my powerline adapters for the ethernet with the wifi off, and I can link to the plusnet hub, so it seems that when i use ethernet with wifi on it links to the EE hub but just on wifi or just on ethernet I can link to plusnet. I have now therefore turned off my wifi and will see what happens. I need the facility to switch it off and on so my phone doesnt always run on mobile data. Oh it is so complex! I prefer not to have the emfs around me that is why i changed to using a wired connected at home.
