Have him try this...
one of the primary points of emphasis we tried to make during the install process is that if a Joey is connected to the MoCA network before the Hopper is activated, it could put the Joey in a state that seems unrecoverable. In most cases, the Joey will show "1303" searching for a Hopper. If a Joey is in that condition, we suggest the following work around to recover it:
(Assumes the Joey is connected to the MoCA network via coax and the Hopper has finished all downloads and activation.)
- Disconnect the co/ax (moCA) connection from the Joey
- Place the Joey in standby using the front panel
- Reconnect the co/ax (moCA) connection to the Joey
- Reset the Joey (AC reset is suggested)
- The Joey should then boot back up to 061 and do the software download
From here the Joey should be recovered.
