However... it looks like the modem access code sticker came off the bottom... anybody know how I can reset this access code so that I can get into my modem?
The access code is on the big
white sticker and on a smaller yellow sticker.
The modem has a page in its gui that will allow you to change the access code. Use the factory reset button to reset the modem that will allow full access to all pages until the modem initiates a PPPoE session
If the modem is a 5100a here's the faq for it
