Advice on extending internet connectivity to annex office conversion, boost wifi or powerline kit?

This is interesting, my issue is feeding a wire through to it. My router is in the living room at the front of the house, to get a wire out back I'd have to go through the kitchen and the conservatory, I can't drill directly out from the living room to feed the wire around the side of the house to the back yard as I live in a semi detached house and my router happens to be on the side that is attached to my neighbor... Unless, I go through the front and get a ridiculously long Ethernet cable to go all the way round the front to the other side, we're talking a need for a 30m Ethernet cable to get round to the back. Do these have to be pointed at each other? I trust these also have to be wired into the mains as well?

I to, as you have eluded to the possibility, am concerned with connections speeds delivered via the power line kits. When I bought the house I was told the wiring was updated to modern standards and I have a certificate to the fact, although that is no real guarantee.

What i am trying to do is avoid the expense of getting someone in to be wiring things in and or drilling holes in my house, I wouldn't have time to enjoy any benefit before the lady of the house ends me.

If I was to choose option 1 is it easy to do and would it be effective with a couple of extra routers?

For option 2 can you recommend a particular kit?

I will in the mean time consider the option you have given me, thank you for that.

Ok I'm sensing the powerline kits not a great option. I'm, hoping to find a solution that totally limits the need for drilling holes and feeding long cables if possible.

So i've done a little bit of research now that I know there is such a thing as "wireless access bridges" and I hope you can give me your opinion on this; as I said my boadband connection and wireless router is in my living room at the front of my house, to get outside I have to walk through the kitchen then the conservitory so feeding a cable from the living room through the kitchen and then outside is really not feasable.

What if I connected a wireless access point/extender inside my kitchen, toward the back wall and then a third wireless access point within the outbuilding itself, eliminating the need to drill any holes, would that be possible? so it would kind of look like

[wireless router in living room]<~~~~~~~~~~~~>[wireless access point in kitchen]<~~~~~~~~~~>[wireless access point in outbuilding]<-----(wired connection)------>[switch]------> out to devices

Or, if totally wireless isn't possible, place a wireless access point in my kitchen, on top of my kitchen cabinat by a section of wall that leads to my back yard, drill a hole in the wall and feed an rj45 cable through and maybe see if I can lay it to reach the out building, so the connection will look like this:

[wireless router in living room]<~~~~~~(wireless)~~~~~~~>[wireless access point in kitchen]<--------(wire through wall)-------------------->[outbuillding] I'd like to avoid this if possible.

Or is the following an option: as per my second suggestion, stick a wireless access point in the kitchen, feed a rj45 cable connected to said access point through the back wall and down the side of my conservitory wall and connect it to one of the Wireless Bridge/Access Point devices you suggested mounted on the back of my house poitnting to it's compliment on the outbuilding, thus eliminating the need for feeding cable through the garden or is this just an unecesserily convaluted way of achieving the first thing I said?

Thank you for your input btw.

Nope no basement and while i do have an attic of sorts the bedrooms are on the first floor so gettings cables up their would defy the attempt to not have wires going through the living areas.

Yes I am in the UK, I am with virgin media, and I have one of their generic first gen "Super hub" wireless routers which is just a netgear wireless router; I think its on a 2.4Ghz band. Mindful of this day I asked the cable guy to install it in the kitchen as close to the back as reasonably possible but he refused opting for the easyest access, i.e the front living room.

The conservatory is just an extension off of the kitchen the electrics are part of the house. The detached outbuilding has it's own submains, is that connected via the mains in the house, I'd guess yes, somehow but that's only becuase I can't think of any other logical way to feed electricity outback unless I'm unwittingly stealing electricity from somewhere else. I only moved in 6 months ago, this was all set up by the previous owner, an ellectrician, so you'll have to forgive my ignorance. My neighbour, a retired buildier, helped the the previous owner build the outbuilding and says the electrics are all cousher, in a manner of speaking, he is actually helping me refurbish it.

I know what you mean about the"super" hub, it's actually quite unrimarkable lol.

Yes there is a mainboard in the house and one in the outbuilding. As per your ingenius and simple suggestion, I tested the electrics to see if the outbuilding mainboard is linked to the house. I turned off all the fuses in the house and it shut off the electrics in the outbuilding, lights and plugs. I was then able to pin point the fuse that feeds the outbuilding. Is this a good sign?

would a single wireless bridge between the kitchen and the livingroom not be able to maintain an (up to) 50Mbps connection at least? if a series of wireless bridges is a bad idea I may be able to drill a wire out the back out the kitchen via a single wireless bridge hidden atop one of the kitchen cabinets. My other options are feeding a wire through the house, not feasable or out of the front of the house, round it, all the way back then across the garden, again not feasable..

I really wanted a second connection but while virgin were more than happy to sell me another package the installer flat out refused, probably a good omen in the end, was made redundant recently so am on a DIY mission lol.

So any help and suggestions is greatly appreciated...

Thanks all, this is very helpful, fortunatly my neighbour is a retired builder and has agreed to help me out, he actually help build the outbuilding in my house. I have a clearer idea of what I need to do.

I found a 100m cat6 outdoor data reel for £50 on amazon with glowing reviews and my neighbour seems to be very keen to get some use out of his industrial powerdrill. A route from the front round to the back might be feasable.

I am very tempted to give the powerline kits a go, the wiring in the house is fairly new and 80-150mbps with a good 500mbps kit would be worth it, @ just £25 for a pair it may be worth a punt, but i've seen forum discussions of them blowing in a year.

I'm going to rule out making a wireless bridge..

Anyway, before I get ahead of myself I need to refurb the outbuilding, plaster the cieling, redistrabute the electric sockets, paint the walls and put down laminate flooring before I worry about getting an internet connection in there..... now to find out what size electrical wire I need for sockets, apparetnly it might be 10mm, but that's for another thread.

Downstairs I'm ok, my gaming rig is in the living room connected via ethernet and I rarely use my laptop outside of the living room when I'm at home, but if I try to use my laptop upstairs or in the garden I have to cross my fingers and pray to the gods of wireless but there is only so much they are willing to do lol.

Think I'll invest in a couple of the wifi enabled ones to boost signal around the house
