[Swansea Hackspace] Slow wifi how to investigate.

Or there's lots of wifi around its all on the same channel - which is
depressingly common because lots of kit doesn't randomly pick a channel
when set up and nobody changes the defaults.

For wifi strength there are a bunch of handy phone apps that will show
you the wifi in near real time.
