to check -
the user name is admin
password is changeme
both lower case
if they have got changed then a pinhole reset will reset them - however it is important that the hub is switched on - yes i know thats obvious but not everybody does and it VERY important that you hold the reset button for a good 30 sec - again obvious and people do - but many dont - they think its 30 sec but it is not - so be patient and make sure its 30sec
