Constantly losing connectivity

In September of last year, I transferred the internet service account into my name. Prior to this change, the service operated with minimal issues. Shortly thereafter, I began experiencing persistent connectivity problems that require frequent modem and router reboots.

After a service conversation with Spectrum’s, I replaced my modem with a Netgear CM3000, as per Spectrum, my prior modem was reportedly associated with the former account and it would continue to cause issues with the service. This resolved the issue only briefly. I subsequently replaced my router with an Orbi 970 Series, which again improved performance temporarily before the service became unstable.

Despite numerous calls to Spectrum, I am repeatedly advised that no line issues are detected and am instructed to reboot my equipment. I have explained that similar problems previously occurred at this location with another provider and were ultimately traced to faults at the external connection point; however, this information has not been addressed.

I have a formal background in information technology and have verified all internal connections, reviewed modem error logs, and consulted with Netgear support. The documented error codes consistently indicate an external line or upstream network issue. I have included the most recent modem log and request confirmation that this matter is being properly investigated.

    Hi @TheRealJoeBrooks

    Welcome to our Community Forum! I'm sorry to hear that you're experiencing intermittent connectivity with our internet service, I'm happy to help! You mentioned that you have a router in place, are any of your devices wired? If so, are you experiencing connectivity issues on the wired devices?

    Hello @TheRealJoeBrooks

    Why not try the free modem Spectrum offers and see if that helps?

    As it stands now, your current modem won't work correctly once the High-Split upgrade comes to your area. When is our Network Evolution coming to you? If you have a Spectrum store nearby, you can get a free Spectrum Modem there. Or call Customer Service and ask for one to be shipped.

    Just be aware that you'll lose the ability to access the modem log .

    The CM3000 is a 3.1 modem with 32x8 and 2x2 channel design. Should still work just fine if you stay on non-symetric plans.

    Sounds like there may be ingress periodically throwing you into unreliable values. Can you see your signal levels at 192.168.100.1? If yes, may be worth comparing them when things are good vs. bad. If there is a notable shift, may want to document it and call for a tech visit to investigate the potential source of the noise. Having snapshots of such weirdness for them can help sometimes.

    Should note, sometimes security gets in the way of getting to the modem's login. May need to direct connect with ethernet to get to the web interface. Had to do that once with an Arris 3.1 Modem. I manually set a laptop's ethernet to 192.168.100.200 and connected it to the second port on the modem and was able to get in after doing the setup (had to complete a setup wizard to change factory password).

    I live Beach side New Smyrna Beach FL. I would like to say the coaxed junction boxes are corroded from years of salt spray. Loss of connectivity due to antiquated and corroded infrastructure. Old or inadequate repeaters. I have rebooted my system many times. I will be on the phone or working with a client and it drops. Frustrating for me and the people I interact with.

    I agree with @RAIST515O and @catchtwentytwo,

    You will need a Spectrum rented modem and Spectrum router once High Split Internet conversion is completed over the course of the next year and a half (approx.) Spectrum won't touch equipment that you do not rent from them.

    I would call and get a Spectrum Modem/router sent out to you and see if that help. Yes, I strongly recommend playing the small additional monthly fee to rent a Spectrum router. This will ensure full compatibility with your network. If anything goes wrong, Spectrum will fix any issues related to their signals or their equipment.

    If you are still losing connectivity you can rent Internet Signal expander pods from Spectrum for a very small fee, or buy an Internet signal booster from Amazon for about $40-$50.

    1. The first thing that I would do would be get a Spectrum modem and router shipped out to you.
    2. If the new Spectrum modem/router still has problems, call Spectrum insisting on a service call for a signal and drop line test.
    3. If that doesn't work, get one or two WIFI Signal Booster expanders.

    All my equipment was provided by Spectrum. D3.1modem 2.5g and a Wi-Fi 7 router.

    Not that old but maybe 🤔 better equipment is available.

    Frustrating when everything freeze up. Eventually blue turns to red and the cycle continues.

    I have lived near the ocean all my life and salt spray and sun will eat any metal and snack on electrical especially low voltage connectors and coaxel cat 2 for desert. I'm no expert but the first thing to trouble shoot the incoming coaxel or whatever they use now. Like having bald tires on a Cadillac...

    I agree 100% They are all digital fiber optic. Call Spectrum and tell them you need a signal and drop line test because your Internet keeps dying. Say something like, "I've done tons of reboots and the problem keeps coming back." They will send someone out and need to do that!

    That's great that you have Spectrum equipment on everything! Your tech will update your Internet equipment if he/she finds your signals are good. If you still have problems after the tech visit, try my Internet WIFI signal booster suggestion I mentioned above.
