I have the standard Vodafone ADSL2 Hawei modem with all-red lights which has stopped functioning.

Symptoms are
Power Light on
Internet light on and solid red as though connected to VF.
WiFi light off
All Ethernet Ports Dead [no lights and no data throughput] so I am not able to access it via the laptop as I would normally and no connected devices have any conectivity or IP addresses assigned.

I was able to factory reset it on Sunday when it first happened and set up the way it was and it was good for about 24 hours then it happened again last night but this time no amount of holding the reset button would trigger a reset and the two lights just stayed on.

When I turn it off and on, only the two first lights as described above ever come on instead of all the lights flashing on at least once and the usual clicking noises are absent.

VF are sending me out a new one today hopefully but in the mean time I wondered if this was a common fault that can be rectified even temporarily.  Would like to at least use it until the replacement arrives.
