[Other] Arris TM1602A Backdoor?

Hi all, I am new to DSLReports, and I just moved to a new house. I had Charter at my old house, with a Moto Surfboard, but the installer gave me an Arris TM1602A instead. I went to 192.168.100.1, and got the modem's status page and stuff, and saw that there was a tab for "Advanced." Being the curious cat that I am, I went ahead and clicked on it. Password, I said? I then proceeded to do some more digging, and found these PoD generators. So far, none have worked. Where do I go from this point? I've included a few screenshots for your viewing pleasure...
