first off, what and where is the infrastructure mode option at? or does setting those other two settings make it go into that mode automatically?
second, i keep getting a 'what the hell!!! your phone took over the wifi and tether shutting down NOW' error after the screen times out and i turn it back on... or just after 5-10 minutes of it setting with screen off, but data in use.
on a hunch, i turned off the 'Power saving' option in the settings menu (of the rom, not wifi tether app). so far, about 5 minutes, and several screen cycles, it seems to be sticking. we'll see!
EDIT: Nope! made it about 10 minutes, then the boot again. i noticed that the wifi was showing that it was on again in the drop menu, and i had just turned it off. so i dug around and found the 'connection optimizer' in the advanced wifi menu. shut it off. waiting to see how it goes this time. (power saving still off too)
EDIT 2: Looks like the Connection Optimizer was the problem. its been up and running for about 15 minutes now, and no problems. ill report back if issues arise!
