5ghz would drop if using the internet for a while. eg:surfing, streaming on youtube, downloading files.
its confusing me because it wont drop at all if im using it to transfer files through smb/ftp. even large files around 5gb-50gb at a time.
lowering multicast rate helps sometimes. but never rock solid. i tried changing preamable type back and forth. didnt help either. using fixed channel just makes it worse, changing channel width too is useless. changing region code confuses me because there are only options for usa,europe,taiwan,china and japan. i live in south east asia, wonder if debug is for me. tried that and guess what, it still drops and i have to disable and re-enable to get it up again. this only happen on any build based on kernel 3.x. previous based on kernel 2.x never had that problem, but it has worse problem which is too long for me to write it all here.
i remember that i have two problems with it, dropping 5ghz and hfs+ drive is not mounting. i can live with both problem, but it would be nice if its working properly in the future.
