it really is a big pain and error prone to enter a WPA key which typically looks like this:
rJ0ZwCLHs$u-isvQVX,3fCSX5NTV5DuvX\JI6eZyWJw41hUV4RYjd#7hDa3Inw3
with the remote. Try that out and you will know what I mean

Please, add a method to read the WPA-Key from an SD card or to add the WPA key through the WEB interface (so users can disable WPA for the configuration, then reenable it).
Thanks,
