====== Reboot loop problem with old firmware ======
<btn type="success" size="xs" icon="fa fa-chevron-left">[[:Troubleshooting|Go back to all troubleshooting topics]]</btn>

**Affected models & firmware:**
  * HDHomeRun PRIME running 20130117 or older firmware.
  * HDHomeRun DUAL running 20141124 or older firmware.


**Solution:**
  - Download the latest software:
    - Windows: **http://download.silicondust.com/hdhomerun/hdhomerun_windows.exe**
    - Mac: **http://download.silicondust.com/hdhomerun/hdhomerun_mac.dmg**
  - Unplug the WAN port on your home router so internet goes down (but your home network is still working). The HDHomeRun should now stay up correctly.
  - Run the installer so it upgrades the firmware in the HDHomeRun.
  - Attach the WAN port again so internet comes back.
