2.4Ghz Spectrum Analyser/ WiFi/ WiSpy

I have been looking at a WiSpy 2.4Ghz Spectrum Analyser with Chanalyzer software and also InSSIDer with a high gain WiFi USB dongle over the past couple of days.

The graphs produced are mind boggling at first but quite interesting. From the various outputs I have discovered that my TV sender is very strong and always transmitting, the flat above have their WiFi AP (SSID Bruce 10) on channel 6 and its very strong in here and that there is a load of noise on channel 11 from 6 other WiFi networks nearby.

So using all of this information I have done the following; moved my TV sender to AV Channel 1 (2.414GHz) - which you can see on the far left of the graphs between WiFi Channel 1 and 2 and I have moved my WiFi from Channel 11 to Channel 13.

On the middle Topographic view you can see the neighbour's WiFi mushroom on channel 6 and mine on channel 13.

Metageek's InSSIDer will run with just a normal WiFi card and I'd recommend giving it a quick try, or else just make sure your WiFi isn't on channel 11. Chanalyzer, also from Metageek, is a bit more specialist and requires the WiSpy USB dongle which you can buy from firstpersonview.co.uk here.
