Calix

I am having trouble with my Calix 844G router and have forgotten what I set my UN/PW to. I am trying to avoid factory reset. Anybody know of a backdoor way into the router for admin page?

Hello. I'm building a computer for my mother after her Mac mini died. It's only my second build so I'd appreciate any advice. Thanks in advance! System Usage: 50-tab internet browsing, 1080p streaming, the odd casual game (like iterations of Bejeweled), Bluetooth Apple mouse/keyboard, emails...
