I have three STBs. One that is a PVR and is working. Two that do not have hard drives and are not working. The non-working ones say "quit client" upon boot. Selecting this reboots the STB.
The non-working STBs typically use wifi but for testing purposes I plugged them in, in place of the working unit. That did not change the symptoms.
Possibly relevant: due to a failed router, the two non-working STBs were offline for a month or more. The network is now fixed and I can confirm the STBs obtain an IP address and respond to ping.
Any suggestions would be appreciated.

Problem solved. Routing tables were incorrect and the non-working units were trying to route via the wrong WAN.
New problem: the two STBs cannot access the recordings on the PVR. This used to work. They are all on the same subnet, all respond to ping, and all can watch live TV.

Second problem solved. Just needed to reboot all units.
