I've been noticing this small problem sometimes with TetherMe. I'll be downloading a file when tethering via bluetooth and all of a sudden the download will just stop at 0.0 kbps and won't start again until I restart the tethering process. I sort of have this problem tethering with USB, but it doesn't happen as often. Also, my speeds are like 3 times faster when tethering via USB. Is that normal? Any insight is appreciated.
