Issues With WIFI & Bluetooth Tethering

[HighOnHops]

Is anyone else loosing their internet connection while tethering. What I am seeing is after being connected for 30 minutes or so via WIFI or Bluetooth, the connection to the external device is working, but it can no longer get to the internet. I do have full data working on the handset at the time of data not working on the external device. After shutting tethering down and bringing it back, it seems to start working again for another 30-60 minutes. Nexus is not rooted running the built-in tethering app.
