    Well to get around some of the suspect illegality, surely a simple solution is to use a high power access point rather than an actual cable or a PTP link system. The fact that you can use your BB service beyond you boundry is common place. At home I have maybe 15 different WiFi's within range.

    Simplest option would be to just use a switch to the other premise rather than a router otherwise you will likely hit double NATing issues. Then all devices in both homes can use the same subnet. Depending upon the router that is used for the WAN connection you could setup two subnets and DHCP on both if more network separation was needed.

    As has already been mentioned this setup will rely on a lot of trust between both parties.

    Some one I know set up microwave dishes between to towns when OpenReach refused to bring in broad band, it ran around a year, as soon as OpenReach realised what was going on they did bring broadband to Ruthin as well as Denbigh, he just about broke even, as soon as available direct then he lost all of his customers, since mainly firms not private houses and some years ago he did not have any problems with illegal downloads, but he did end up with a lot of equipment which was redundant.

    But the distance your talking about does not make sense, if you can run a cable so can openreach, seems more likely two parties want to share cost rather than not being available.

    Why is it illegal?

    It probably breaks the contract he has with the ISP, but that would be a civil matter, not illegal per se.

    A few decades ago ( GPO days ) running any communications cable between two properties that involved crossing a third person's property had to be a GPO installed Private Wire.

    I would assume that is no longer the case (*) provided all the property owners involved agree to grant a wayleave for the cable to cross their properties.

    (*) or it is still the case but simply is not practical to enforce against short distance and concealed DIY private wires.

    I believe it is an offence of trespass to run a cable without the necessary wayleaves.


    It will be necessary to install adequate isolation at both ends of the link to prevent data corruption and /or damage to equipment from potential differences. Most routers have a floating ( un-earthed ) supply to the electronics which means the internal 0 volts is floating about mid point between Neutral and Live, hence about 115 Volts AC above ground potential. This coupled with the capacitive coupling from cable to Ground ( earth ) may corrupt data. If the two routers are supplied from different phases of the local mains supply network then the potential difference between their respective 0 Volts will be greater than 115 Volts and this could damage the routers if adequate isolation is not provided,

    Isolation, etc not a problem if using a wifi PTP solution!

    We have a Point to Point radio connection linking our two factories. They're about half a mile from each other but with a clear line of site.

    The system has been faultless in the 4-5 years that we've had it and the system makes the other site appear as if we're linked by physical cable.

    It would be my preferred option for what the OP has proposed.

    Indeed. I've never bothered to look, but I would assume that (for fairly obvious commercial reasons) ISP contracts forbid the sharing of a single internet connections whether cabled or WiFi by several households/whatever - but, as you say, that's purely a civil matter.

    Kind Regards, John

    My internet connection is, and has been for many years, from a microwave dish on a nearby hill. A company was set up to provide that service to my, and surrounding, villages at a time when BT's (copper) cables could do little better than 0.5 Mbps. Subsequently, BT have brought an optical cable to the village and, more recently, Gigaclear have cabled our village. However, my ISP seems to be continuing to do fairly well (i.e. surviving!), with its microwave PTP system, I presume because many/most of their customers (virtually all private houses) find the service (8 -15 Mbps for some, up to about 32 Mbps for others) to be more than adequate for our needs.

    Kind Regards, John

    Whhoooooaaaa OK. Was not expecting all those replies :)

    Thanks all who mention it's illegal, it's not. *If* the ISP does not know about it then it is against terms of service. Fact is, in this instance it is a property not served by an independant provider that offers gigabit fibre because this house has no duct having been built in a garden. So, we are looking at delivering it in an outbuilding and then running a cable to his house. This will almost certainly be done with the providers blessing however at worst it will be purchased by the home owner and refunded by the neighbour. Worst case and they share, it will be the business service and we'll vlan the traffic and outbound NAT giving each household their own public IP. For those offering advice on how to route the traffic or what router to use, we're cool and have that covered thanks.

    So my question remains I think, with a direct ethernet connection do we need to think about earthing? <EDIT> Thanks to BernardGreen for answering! <>

    Of course, the other option which is probably going to be my way to go is we'll use armoured fibre NOT copper and that removes that issue completely but I am intrigued anyway.

    Finally, proponents of WiFi, yes we did think of that but ironically it's messier by tacking cables and things to walls than a well hidden cable. Oh and there's a LOT of trees, trees have water, water diffracts signal and it will be difficult to get enough height to satisfy fresnel zone requirements to give us max speed.

    Thanks

    Long since repealed when liberalisation happened and the GPO, later BT, lost their monopoly.

    So who would you use to run a single pair from one house to another house across the road. ?

    Please do not avoid answering this question.

    Now or then?

    If then the GPO who would most likely run a pair from each house into the local exchange and jumper them together.

    If now I don’t know.
