Will need to see which version of the board I have inside. Seems there are a few.I'd flash the FW ASAP then you can go for WRT be it Open or DD.
Yeah alright, don't rub it in.I'll open mine inabit. Been using it loads today on my pi!
(I tried to get one today and failed lol
)
Hopefully in next few days 
and also an aerial on here, much better!!
