    I have a pretty poor wifi signal on my AirPort Time Capsule - 3TB... and I'd like to change the 2.5Ghz/5Ghz channels to a stronger frequency.
    I haven't touched any of the channel settings just yet, both bands are currently set to the default 'automatic' setting.

    - How can I find out what channels are the strongest, is there a handy tool to measure signal strength, or do I need to manually check each of the 13 channels?
    (which makes 26 different channels in total, considering there's both 2.5Ghz/5Ghz)

    The more important question is: What channels are being used by those around me.


    Here is a great app to study WI-Fi:

    You will need trial, error, and the Mk1 human eyeball to find the balance between least congested and least interfered channels by looking at practical performance, and then it might change a few minutes later. If you're lucky some of the PC software for WiFi adaptors has a scanning function (got it on a Dell Latitude) which will help rule out the worst choices. As a guide try to find a channel which has a gap of at least 2 channels from any strong signals (except your router which you plan to move) - so if Ch6 has a strong signal you should avoid selecting 4,5,7,8. Most likely you will find quieter channels up in the 5GHz band.

    Get an app that will survey the wifi landscape (I use Wifi Explorer for this and other functions)... it will show you what channels are in use around you and provide you with information about possible channel collisions, etc.
