General (#3) - long preamble (#5) - Message List

On the stock firmware, any way to hack around the need for long preamble? AFAIK, long preamble is deprecated with newer hardware, and as I am not in control of my corporate wireless, I can't use the Z2 at work :).

Alternatively, if I can get an OE build with better drivers not requiring long preamble, maybe that would work better?
