I want to make our internet connection available to another house about 100 metres away - with direct line-of-sight.

Too far for standard wifi to work reliably (even if it worked on the drive, I don't think it would do so inside).

I am well aware that various pairs of devices are available which can do the job. Do you have any recommendations? Least expensive that will do the job without being rubbish.

Doesn't need any fancy facilities at all. I have a wifi router I can use inside. So this is just for the house-to-house link.

a standard pair of router will work IF you remove the supplied antennae
and bang in some sort of mini directional antennae and line em up

Have you considered connecting one or more directional antennas to a
WiFi access point that has RF connectors? High gain
Yagis, log-periodics and multi-element patch antennas can be found on eBay.
Alternatively, have a look at Ubiquiti and MicroTik who both make a
range of point-to-point ethernet repeaters.

It's worth a go, but also to point out that a lot of these were designed in
the 802.11b era, when top speed was 11Mbit/s. It's worth paying close
attention to any set of instructions you follow as to whether it gives any
speed measurements.

Back in the day, 1Mbps was ample when you had a 512Kbit/s broadband
connection. Nowadays 1Mbps broadband is unusable.

The absolute cheapest way for that sort of range in in true DIY style is
a pair of cantennas made out of old Pringle cans and some RF bits. Some
soldering and slightly dodgy RF legality is involved in such a bodge.

I chose to do it with a normal router and a flat plate 14dB antenna and
a cheap (intended to be sacrificial) USB Wifi dongle with removable
antenna at the other. This was to extend my personal Wifi to the VH for
doing computer classes when I wanted internet. That is about 100m.

I had planned to make a cantenna (indeed I dutifully ate the caustic
crisps in the can) but ran out of roundtuits before I needed to have a
working solution and quickly so I bought the right bits.

I am well aware that various pairs of devices are available which can

I'd try this dongle from Morgan at the far end together with a high gain
antenna and suitable interconnect cable from Solwise.

https://www.morgancomputers.co.uk/pr...ntenna-Dongle/

This one is the cheapest now and looks very much like my 14dB unit.

https://www.solwise.co.uk/wireless-o...panel-10pn.htm

Extra directional gain is helpful so you probably want the next one up
which looks somewhat different. You can use an outdoor antenna indoors.

You do need to be able to point the thing moderately accurately in about
the right direction but it is nowhere near as tetchy as a yagi. I hung
the remote antenna in a window facing my house when I needed it.

Shorter distances to the garden shed you might just get away with a
right sized foil parabolic cylinder behind the original rod antenna.

If the two antennae can be sited with line of sight...

I set up a link of 3/4 of a mile some years ago, using two modified
wifi routers and carefully aligned homemade Yagi antennae. I
disconnected the built in antennas and used good quality 3Ghz coax no
more than a couple of meters at each. My link worked rather well,
despite there being lots of other wifi along the route.

While there are a number of "crufted" solutions adding directional
antennae to normal wifi kit, you can get proper self contained external
bridging units fairly cheaply these days. For example, these can be had
for under £40:

https://www.tp-link.com/uk/service-p.../cpe210/v3.20/

If you set them up in bridging mode, then they look just like a bit of
layer 2 networking infrastructure (e.g. like a network switch), they
become "transparent" and behave much like you had strung a long ethernet
wire between sites.

I did this for an elderly neighbour for a while. We had a diagonal
line-of-sight across a fairly wide road and front driveways that I'll
measure by pacing out the next time I go out.

I was able to run a Cat5 patch cable from her spare front bedroom to
her router in the lounge and put a Bridge / AP / Ethernet to WiFi
adaptor on the windowsill in that bedroom window.

My AP happened to be at the front of the house and I was able to get a
pertty good / reliable link with just that.

In fact, the only time we generally lost the link was if a removals
lorry parked in the road between us. ;-)

I helped set up similar for a mate in his workshop who wanted Internet
access and was given permission by a local company to use theirs.

We positioned a (TP-Link) WiFi repeater (in this instance) fairly high
behind some wooden facia and it has been able to provide a reliable
link so far (couple of years)?

Again, only really has any issues if a large lorry parks between them.

As an experiment with another neighbour here I setup A TP-Link device,
an AP in this case (TL-WA801ND) again in Ethernet to Wi-Fi mode and
with it stood on my front bedroom windowsill (with the aerials looking
though the glass at his house), I was able to connect to his network.
In this case it was to try moving some big files but the link speed
was reduced and it was pretty slow. That unit has removable aerials
And I tried a small Yagi on one but can't remember if it helped at all
/ much (mate would probably have to do the same his end).

That's why commercial laser links use IR lasers.

Should imagine the really hard part is having a sturdy enough mount
that is easy to align but doesn't wobble. Doesn't take much movement
of the laser pointer to shift the dot 100 m away quite a distance.

A friend of mine did this with a couple of woks to get from the village
to his farmhouse, but he's an electronics guy who knows his stuff and
likes tinkering.

Pringles can cantennas aren't very good, but using a larger diameter can
works, plenty of info online.

The problem is not the outgoing, but the signal from the device, which is
why you really need a remote hot spot connected by some kind of system made
for the purpose.
