I have added the firmware update V5.6.6 210625 to one of my 2055 cameras. It now does not let me have live view in IE or firefox. i keep getting the little note box in the bottom right corner saying "Live View Failed".
EDIT
all sorted and working.
Once again thank you so much for your help today Kyle.
So I now got all my 11 cameras done now with there new up to date firmware.
My 5 x 2055 cameras are now up from 5mp (2560 x 1920) upto 6mp (3072 x 2048) which I am very happy with.
