My internet sharing works, but signal is not the most reliable. For some reason, using Access Point is the most reliable, but you will internet sharing.
And yes, my signal drops all the time, but this is the case I've notice with any AT&T phone on Tmo. Also tried Note 3, G2, 920, s3, iphone. All doesn't have reliable signal like my 925, note 2, s3 (Tmo.). If you want reliable signal, stick to tmo phone.
