Thanks Burakkucat,
I managed to reset it finally. Although I had to deviate from your instructions slightly to get it to work.
Here follows is what I would try to recover access to the device.
- Disconnect all leads.
- Press and hold the reset button in the operated state. With the other hand, connect the power supply.
- Count to ten. Now release the reset button.
- Wait, say, two minutes.
- Connect a standard Ethernet patch lead to the LAN2 port and the other end to a computer whose network interface has been given a static IPv4 address in the 192.168.1.0/24 subnet. Any address other than 192.168.1.1 or 192.168.1.255 will do.
- Open a web-browser and access the 192.168.1.1 address. The "Update Software" screen should be displayed.
- Locate the firmware image and enter the file name in the relevant box.
- Left-click on the "Update Software" button.
- Leave both the HG612 and the computer alone for, say five minutes. It does not matter that the computer might say that it has a problem in accessing the device. That is perfectly normal.
- After five minutes have elapsed, power off the HG612 and disconnect the Ethernet patch lead from the LAN2 port.
- Power on the HG612 and leave it to fully initialise. A couple of minutes will do.
- Press and hold the reset button for 15 - 20 seconds. Release the button and leave the device re-initialise for, say, two minutes.
- All being well, the HG612 should now be back to the unlocked, factory default, state. It should be accessible at the 192.168.1.1 IPv4 address via the LAN2 port.
So now I have it powered, Lan2 connected to my laptop. Still no ping. So the next step I did:
- Press and hold reset for 10-15 seconds while powered on and lan2 connected. The power and Lan leds briefly turn off and on doing this.
- Wait for a minute or two
- Can now ping 192.168.1.1 and access web panel!
Thanks for your time Burakkucat, I am cooking on gas again!
I think being a little patient and waiting for the thing to think and get everything in order before a reset was needed.
I guess the modem isn't that sophisticated to allow PPPoE and do basic local lan IP on the same port, like my other modems. I was hoping to keep the cable clutter down. But it's not a massive issue.
