Correct my WiFi stopped working last night, and customer service said it's outdated and said I need a new modem. I purchased it in 2019. Then tried telling me I can rent a panorama modem for 15$ a month. I said no thank you.
When I go to that website I see the S33 as supported and approved for the 2Gbps service plan. I also see the SB8200 as supported for 1Gbps. What am I missing? Can you show a screenshot? Are you mistaking the Wifi Yes/No for not being supported?
Perhaps, but I wouldn't be surprised to see newer/better DOCSIS 4.0 modems come out on a regular basis. Every few months or so a newer and more capable devices will typically become available. If you look back at DOCSIS 3.0 for example, the 1st modems were 4x4, then 4x8, 4x16, 8x24, 8x32.
There's nothing wrong with using an SB8200 but at you stated it's 4 years old now so plenty of newer devices have since hit the market.
