I bought a Arris SBV3202 cable modem in 2019 and have been using it on Comcast. It was on their approved list of modems. I am paying for Superfast 800Mbps internet service, and I was achieving 600-700Mbps regularly over the last several years.Over the last few months (since I have noticed), the speed has been consistently 200-300Mbps. Comcast checked it out today, and told me my modem is defective and needs to be replaced. My modem is no longer under warrantee. Is my modem defective, or has Comcast changed their requirements? Do I need a more modern model, like one with DODISS 3.1, or something? Do I need a firmware update? Any ideas?It is hard to get a straight answer out of Comcast customer service.If it is defective, the only Arris Voice model that is now recommended by Comcast is the T25. It’s max speed is 925Mbps, which isn’t much of an improvement from the SBV3202, other than it is a DODISS 3.1. Is the T25 a good replacement voice modem?
For a newly installed SBV3202 with Comcast, everything is working great for both internet and voice but there’s one remaining irritating problem: regardless of Comcast voicemail status I get a stutter tone before every dial tone. Comcast tech came out and we could not clear it, including communicating with the central office who reprovisioned the modem, reset all features on the headend switch, and we of course power cycled the modem. We also tried it with the battery installed and without.More details: Battery LED is always off, I get reasonable text on the modem’s CM State page of “No Status Reported” and with the battery in it shows a Battery Serial Number and Part Number. The SBV3202 manual says on p. 21, “The SBV3202 will transmit a two-second stutter tone when the battery level is low.” But I don’t think it’s low (Batt LED off, modem works fine when I pull the plug). Again, I tested this both with battery IN and OUT.Has anybody else experienced this, or any more ideas? It’s not a
My new SBV3202 was recently activated and data works.Voice on new modem has never worked (the Voice Line LEDs on modem do not turn on) and no dial tone from either Tel port.I have done Modem Resets, and used the Xfinity ‘Activate Voice’ page.My telephone works fine - same one used with previous (netgear) voice modem.Talking with Xfinity is such a pain… thot maybe there was a modem setting I should try first?Thanks.
I have a Netgear modem connecting to Xfinity. I have a new SBV3202 that I want to replace the Netgear with. Per instruction from Xfinity, I installed their app on my phone….and assume it would allow me to ‘activate’ the SBV3202 after I swap out the Netgear.However, I am in a ‘dead’ cell service area….phone only works thru wifi. Can I activate the SBV3202 without the xfinity app?
