Merlin have mentioned .364 is in works, but is it available to download and try? Usually I do this without hesitation. For example, 345, 352 were much better for me than 270. At this time i'm using 354.27, but I recently found, that my samsung ES8000 TV is still dropping connection on 5 Ghz network... Want to try new firmaware, let it be beta, no problem at all.
No binary build available yet. I only fixed the last merge issues late last night, and there is still my own internal testing to do before I even merge it in the master repo. Plus I want to give Asus more time to possibly release fixed drivers before making a new release myself.
The 5 GHz issue won't be fixed until Asus releases new wireless drivers.
