The house seems very resistant to letting WiFi signals out, especially at
the back.

I was wondering about an external aerial or perhaps a complete Access
Point to take the WiFi out into the back garden.

My first search was confusing; some very cheap options and some very
expensive options.

I assume that I want to have 2.4 GHz and 5 GHz and either a complete unit
with Ethernet connection (power over Ethernet?) or a router inside the
house with just the aerial outside.

Has anyone done this?

Cabling and connectors at 2.4 and 5GHz tend to have a bit of loss, so once
it's got to the antenna you've lost some of the signal and so part of the
point of getting the signal there. Additionally modern access points use
phased antennas for better reception, which you can't do with one or few
randomly placed wired antennas.

I'd suggest going for an external unit with an ethernet connection: either
externally mounted or mounted just internally (eg maybe the roof lets signal
out where the walls don't). Most units designed for outdoor or ceiling
mounting use PoE so you just feed it one cable for both data and power.

You can also use mesh, if you can put the unit somewhere with power that has
a whiff of the indoor signal but also a route for its signal to get out.

Its a pity all hubs can't mesh together and do away with the individual
cost.

802.11s is a standard for exactly that. I've tried it on a collection of
random routers running OpenWRT. Support in chipsets is a bit mixed so I
never got it to work reliably (the wifi chip in the BT Homehub 5a wouldn't
play ball, which are most of my pile of scrap routers). But would be doable
if the hardware was designed to support it.

I did that, with a router in the roof to ensure a reliable signal from
the camera in the wall lamp by the front door. Haven't tested the
range for other purposes.

I'm still chuckling at the idea (Daily Mail) that China will be able to
turn 2/3rds of these things off on a whim:-)

I went with multiple wired WiFi access points networked together with
Ethernet cable, with fast roaming.

<https://www.amazon.co.uk/Mercusys-over-100-Devices-Halo-H50G-3-pack/dp/B09C7JDYJ1>

I was confused, thinking I wanted mesh. What I really wanted was to be
able to walk about my house and be connected to the right access point,
without dropouts. That is called fast roaming.

This Mercusys, kit is nasty, in that admin is done via a cloud service,
presumably in China. But... it works reliably. Probably if you pay a bit
more you could get something with local admin.

Do you have a room with a window, facing the garden ?
That would be a great place to do a test.

You probably own materials that could be used to
check how opaque the house is to RF.

1) Cell phone signal. A different frequency than Wifi.
Does that penetrate the house ?
2) Take a bluetooth speaker or battery headphone outdoors (2.4GHz).
Can the computer in the house, pair with that, or
send music to it ?
3) Does your DECT phone work in the back garden, with
the DECT base unit sitting in the house ?
4) Use the USB Wifi on your desktop. In Windows 11 there is
a Hotspot button, which turns the desktop Wifi into Wifi Direct
(an Access Point with its own SSID). The hardest part of
using that, is finding the dialog that has the randomly
generated password string, so you can enter the password
out in the garden, and get up to 54Mbit/sec transfer rate.
It's a pitiful rate, but this is just a test of whether
a Wifi signal can make it outdoors.

2.4GHz is better at penetrating house walls, than 5GHz is.
5GHz was preferred at one time, because there was relatively
less usage of the band, so the channel wasn't as crowded.

If your DECT phone is on 900MHz, that should be really
good at getting through a wall. The DECT frequency used
in the design, can vary with country.

The router signal is a three dimensional signal. At one
time, if your router lived on the house main level,
other main level devices worked. The computer in the basement
might not see a signal. The upstairs bedroom may have poor
reception. (The single antenna on the router back then,
sent signal mostly on the same floor it was on.)

On a router with more than one antenna and
the antenna is hinged, you can try altering the angle of the
antenna, to provide more signal to other parts of the house.

The router signal also has channel numbers. Like Ch 1, 6, 13.
You can try changing the channel, if there is too much
interference from a neighbours choice for their kit.

If your house walls were filled with foil backed insulation boards,
that might be sufficient to cause a problem. Steel door frames.
Aluminium window trim. Those could contribute to a poor result.

The router might have a 2dBi isotropic antenna on it. This
is intended to spread signal in all directions in a house.
The transmitter power (in watts) is limited, by the manufacturers
knowledge that only a 2dBi antenna is on the output. If instead,
you find a 30dBi dish antenna, and point it at the back garden,
that violates the EIRP of the resulting "system", by 28dB.
But, that's also a test case. It's not particularly a
good investment, an illegal antenna, but it's one way
to satisfy your curiosity about whether another
device will ever see your SSID. As you were planning to do,
I would set up an access point or a mesh routing scheme,
before using a dish as my chosen solution. We don't know
how these work bidirectionally, and whether one direction
works as well as the opposite direction.

# Parabolic dish antenna

It could be, that the router has degraded with time, and the
signal isn't actually as strong as it was when the router
was new. You might be able to use your recollection of performance,
to judge whether that has happened. Routers can use adaptive
transmit power, so even if the claim is its 2 watts, if
it detects good signal level, it can turn down the transmit
so it's not as hard on any cheap CMOS output.

And we get scattered reports, about "people with weird scan results".
In Linux, someone was complaining that half their Wifi SSIDs
had gone missing, as if there was some kind of pattern based
on the SSID name or something. If there are sun spots or other
natural phenomenon, that can temporarily affect radio.

A lot of interference cases, are temporary, and those would
be worth listing, if your Wifi "worked sometimes and not others".
But your symptom report is, it never works.

TPLink lists TL-WA801N, TL-WA1201, TL-WA901N, TL-WA3001 in increasing price
as Access Points. The cheapest is 1/4 the price of the most expensive.
The second from the left might be adequate. These are not particularly
designed to sit in the rain, they're not outdoor units, but if you had
a window facing the garden, might be worth a try. You would want to
inspect for evidence of good firmware, good lifespan (no reports of
reduced signal after 3 months), rather than just blankly staring
at the standard "AC" and assuming you'll get lightning speed
and that's it. When there was a review site available for this
stuff, and a guy who cared about benching and measurements, the
whizzy stuff never seemed to pass about 100MB/sec (and that's on
equipment where the WAN side was fast enough to do better). I would
probably select "any old thing that wasn't 802.11n".

For example, now that Wifi 7 is out, I'm not "hungry" to buy new kit,
just because the stupid thing has 4096 QAM or something. Abusing
QAM like that, eventually has to give a diminishing return in
the real world, with real world impediments. Putting AI inside
the box won't help. Etc :-) And without trustworthy reviews, it's
not possible to even remotely guess whether a whizzy thing is
worth "spit". One guy had a real test lab, with real lab equipment,
anechoic capability, attenuator matting for multipath reduction
and so on. But I suspect he's tired of doing test, and is in the
back garden in the sun now. If no one can draw us a graph, using
a "standard house test", it's pretty hard to make an equipment selection.

One part of the selection process, is downloading the manual to
see if the device has a web interface that is decent.

You would likely pay more, for a device packaged for a life in the rain.

Thanks for the useful information so far.

More information - I have a TP-Link WDR3600 in the rear living area, about
5 metres from the bifolds.

A wifi camera just outside doesn't get much signal.

{SFX someone wandering around with a phone with a wifi analyser and
getting distracted by various things}

I also have a cheapo Netgear WAC104 in the back bedroom fairly near to the
window to try and provide a better signal that from the Buffalo router in
the office or the above mentioned downstairs router.

[Another diversion - couldn't understand why there was no signal from the
downstairs router.
Turns out it hadn't been switched back on after our holiday away.]

Also I apparently have WiFi scan throttling enabled on my phone.
No idea at the moment how to turn it off.

I am not clear on how/why signal strength seems to vary at one spot about
2 metres from the downstairs router

All I can see so far is that the bifolds significantly reduce the signal
when I go just outside.

The rear of the house including internal walls does contain a lot of solid
insulation with foil covering.

I think an external AP would probably give a wider scope for WiFi devices
in the back garden.

One day I might even get Ethernet to the Mother Of All Sheds.

[More investigation to follow.]

I think you have to enable developer options, then it's buried within

What's the wavelength of that stuff? Reflections could be causing signal
cancelation if a signal and reflection are out of phase.

Some IoT stuff only has a 2.4GHz radio, which can mean it can't get signal
when all your other devices (on 5GHz) are working fine.

Some glazing has a solar control coating on it which blocks RF.

That won't help.

You could run ethernet to the shed and then put the AP in there :)

Surely the other way around? I find 5GHz next to useless in my house as
2.4GHz has a much better range. Maybe not got the same bandwidth as 5GHz
but 99% of the time adequate bandwidth.

Depends. 5GHz has less penetration through walls etc, which means the 5GHz
spectrum in your house is quieter and less affected by your neighbours. If
you are in a populous area there can be so much 2.4GHz mush that sometimes
it's hard for devices to get the packets through.

Many IoT devices are based on cheap silicon that only has a 2.4GHz radio and
a single antenna, which can be more affected by this than phones and laptops
with multiple 2.4 and 5GHz antennas.

I have x2 Ubiquiti APs in my house at different locations, and I get an
excellent signal outside in the garden

I have a router/access point in the loft, second one on ground floor
(2.4/5Ghz). I fitted a 2.4/5Ghz extender, outdoor, in my hut, to improve
garden access. It works quite well.

Mounting the router indoors, connected to an antenna outdoors, there
will be high losses via the coax - so you would need to consider
mounting the router very close to the antenna..

There really shouldn't be. Pretty much all RF coax is 50 Ohms, and most
small commercial antennas are nominally 50 Ohms.

As long as the antenna is a 50 Ohm type, losses should be small.
Something significantly different (e.g. home-made dipole, folded dipole)
will need a matching balun transformer to talk to 50 Ohms unbalanced,
and a commercial antenna will typically be supplied with one for use
with 50 Ohm cable.

Other coax impedances are rare, apart from 75 Ohms for video, which
will also work for dipoles, but most RF devices will not be expecting
that. Balanced twin feeders will be used for 300 Ohms, it's difficult to
make coax of that order of impedance.

These days most devices have a 5GHz capability. And it's generally
faster if you can get half decent reception.

https://www.amazon.co.uk/20-Metre-Pro-Extension-Cable/dp/B00OZQRNSC

Suggests "Approx 0.22dB loss per Metre for 2.4GHz applications. Approx
0.36dB loss per Metre for 5GHz applications".

So it rather depends on how farther hut is away from the source.

If any distance I think a better bet is Ethernet with POE supplying
power to an Access Point in the hut.
