-Trying- to Tether, this is ridiculous!

[Jewcifer]

I just upgraded from stock to MightyROM just so I could get stealth tethering, and now that same tethering is screwed completely up!

USB tethering: knocks me down from EV to 1x (3kbps down) upon connection.

Wifi Router: Blazes at 500kbps, but randomly shuts off after 10-15 minutes. It doesn't even say it shut off, my laptop just randomly loses internet connectivity while retaining a wifi connection and I have to soft reset to get it back for 15 more minutes.

I'm on U.S. Cellular (Same hardware as Sprint).

Any ideas?
