Hi, I hope someone out there more knowledgable than I am can help me. (I am really quite lost when it comes to ethernet/LAN, and settings. I have Spectrum (formerly Time Warner) for my internet, cable & phone service and have their Arris TG862 modem. I purchased a new Macbook Pro in November. Decided it was time to finally back it up to the Time Capsule (purchased in December.) I was able to back it up on June 18 through June 20, but now neither my Macbook Pro or my desktop iMAC can connect to the Time Capsule at all. Apple told me I need to ask Spectrum to disable the router in the Arris TG862 (they're telling me it's both a router and a modem) but Spectrum is acting like that isn't the problem. Any suggestions? I would REALLY like to be able to use the TC for back up.
