Hi there, I've got the AEBS model before this current version with dual band. I wanted to know if it's possible to make mine dual band or not? There are no options available to do so, even if I press Option on the Radio mode selection. I'm pretty damn sure that once when I was upgrading the software for it, it had an option to install this (it was an official Apple dialog). I'd really like to try it if possible because otherwise it seems a bit lame but if I can't then never mind. Thanks in advance.
