I wonder if the 30 s reset procedure works for this modem same as the VMG 1312-B10
A?
This is the recovery procedure that I use
* iPad to 192.168.1.11 / 255.255.255.0 / gateway 192.168.1.1 by choosing manual and then hit manual again after entering the values
* Plug ethernet cable into modem’s port 2 or 3 and into main switch
* Unplug router if any from main switch
* Power the modem off
* insert a pokey implement into the modem’s reset hole to depress the switch (there is a similarly sized but protruding WPS)
* Power modem on, keeping poker poked in all the time still
* Keeping poker in, LED will flash for 20s then go solid red
* Release poker
* If the device is left in the solid red light mode then a recovery page should appear at
http://192.168.1.1, but only if the ethernet cable is connected to port 2 or 3. Port 1 or is it 4 -which is it -will not work, depending on which way you read the port numbering. (I think the port on the far right is the bad one.)
* file selector prompt, select the firmware file
* After you hit enter at the load firmware prompt, after so many secs the screen should change to show a [back] button. (If not, then you may have put cable in the wrong port, so check it is in port 2 or 3)
* Takes forever to blow flash, no UI feedback
* after 2 mins the modem will reboot (no progress indication)
* When the modem web UI comes up, at
http://192.168.1.1: log in with username=admin, password=1234
* Forcible password change, set password to standard admin password
* using menu option "configuration" > "restore", choose the XML config
* When you have waited for a minute or so, hit refresh in browser
* you have to make sure you go back into the the "configuration" menu again, then modem will reboot
* Modem’s IP address will now change - it will be wrong when the modem boots, so set your machine to 192.168.n.11 / 255.255.255.0 / gateway 192.168.1.1
* When the modem config is loaded, check for the good version string in the "system" menu (top menu on extreme right)
* telnet into modem, log in as "supervisor", with supervisor password
* Telnet CLI : Enter the command : save_default clean
* All done
