I wonder if a lot of wifi problems are down to modern homes being built with concrete blocks, that are cured (or something ) with aluminium spray, which is slightly conductive, so gives a faraday cage shield. In our house you can pick up the signal anywhere in the original part, but very badly/not at all in the extension.

Any type of obstruction (including a human) will have a serious impact on signal strength/quality. Cheapest solution if you want to remain wireless is a range extender.
we use the first one here and its brilliant we pick up the signal from around 100meters away so we can use the net,
At my local yesterday enjoying the sunshine & a BBQ and I decided to do a quick sweep of what wi-fi spots were available.
Our local is only 50 yards or so "as the crow flies" from our house, but there is a hill and houses blocking the direct "line of sight" path so plenty of obstacles to kill the signal.
My access point came up in the list, and still managed a respectable -58dBm for signal strength

Actually I've just had a thought.
The radiotherapy has to be somewhere around the 2.4GHz band, I wonder if I could just stick one of the antennas up my backside for 10 mins a day instead of having to drive to Guildford 5 days a week to get it nuked
