Wifi is now perfectly reliable and secure. It was not always true.

Must live in a cardboard house. Have a place with proper walls (14"
to 18" random stone) and WiFi just doesn't get through them. To get
reasonable coverage I need 3 (well placed) APs

I have some walls 3' thick in places - there are some dead spots. My
Wifi is upstairs and the wooden floors don't put up much resistance.
My WiFi will reach about 300m in free air with the right high gain
antenna at the other end.

Increasingly it is modern homes with foil backed wall insulation that
present the most difficulties for WiFi coverage.

I recommend the WiFi dongles with detachable antenna and a high gain
flat panel for difficult to reach garden sheds etc.

Alternatively, at sub 300m ranges to the shed, the more modest gain of a
cantenna would likely be more than sufficient for the job (neater and
more compact than a wok antenna).

I was going to make a cantenna (in the true spirit of DIY). I had all
the bits and had even eaten up the Pringles but ran out of time and
bought an off the shelf flat panel 18dB gain antenna instead.

USB Wifi dongle was chosen because it had the right chipset, detachable
antenna and expendable since they were remaindered at £5 each. They have
gone up a bit to £8 but appear still to be available (newer chipset) :
