Abstract: Establishing an encrypted communications channel without prior knowledge of an encryption key is disclosed. A gateway router device receives, from a server device via an intermediate modem device, a first secret key code for use in establishing an encrypted communications channel between the gateway router device and the modem device. The gateway router device makes an attempt to establish the encrypted communications channel with the modem device using a pre-shared key that is based on the first secret key code. The gateway router device determines that the attempt to establish the encrypted communications channel has either succeeded or failed. The gateway router device, in response to determining that the attempt to establish the encrypted communications channel has either succeeded or failed, performs a success action or performs a failure action.
