Hi Dussell
The issue is the RT5370 configured as a SoftAP, as can be seen by the comments in the thread, hostapd suffers from intermittent segmentation faults.
The intermittant nature of this makes it unusable.
There may be later versions of raspbian (ie Jessie), which have addressed this, but this is not a priority right now.
If you are interested in trying to solve this, I would be happy to have an experiment in which you can build an OS to run on PiB+ And Pi2, to configure an RT5370 as a hotspot/softap, preferebly on wheezy, but if not jessie would be acceptable.
Fancy a challenge ?
Thx
Lee
