Cable modem question

So from my Cable internet provider I have a cable modem. It shows in the settings as DOCSIS 3.0. however checking out the settings, it shows its getting service as 2.0 ( I don't have access to it right now for correct wording). Why would it do this?

I have taken notice to slower speeds then normal, and having to reboot their modem. It's a POS. I leased the modem from them, which after having them for a year, I now own it. So they will not replace it without me paying for it.

So I said screw it and I will be buying the MOTOROLA SB6121 SURFboard cable modem. Does anyone else think this will solve the problem? I am tired of always rebooting their modem daily.

I really wish Comcast would get to my area, but the local cable company blocks them from having service here. So from their ****ty service to their ****ty prices I am tired of it.

10MB down, 786 UP for $57 a month. I'm going to upgrade soon to 15 down and 2 up for $62 for the year.

Later tonight I can copy and paste the info from the modem.

Call your cable company would be my first suggestion. They will need to test and verify your db at the modem. If you moved it you may have some loss, if they made a change at the pole you may have some loss.

If you are leasing it, regardless of how old it is, they should be replacing it or there should be no further charge on your bill for leasing your device.

I'll call them again about it, but since I own the modem now, they wont replace it for free.

'but since I own the modem now, they wont replace it for free."

So your NOT paying anything for the modem for on your bill then.. So its not like you leased it, you just bought it from them on a payment plan.

If they are still charging you a modem lease fee, then they should replace it with their current modem if there is something not working on yours.

If your modem is suppose to be docsis 3, but your only getting connected at docsis 2 - then seems more like an isp issue and not a modem issue. Purchasing your own docsis 3 modem would not fix an issue on their end.

Where exactly are you seeing your only connected via 2? Could you post what your seeing that makes you believe your only on docsis 2 vs 3?

I personally don't like the lease option on any sort of hardware - I will just buy my own thank you ;) I have a SB6120 and have not had issue one with it, on comcast. But if they were just charging for it, and then stopped - that just sounds like some sort of rent to own thing, not a normal cable modem lease deal.

I don't have it in front of me right now. Once I get back in a few hours I'll take a screen shot of it and post it. I think it was under status or something like that.

I am also going to call them tonight or so and find out if they know of any issues.

How do you fix that?

Leave the modem connected 24/7 and the exchange will slowly ramp the speed back up until it reaches your lines max speed you got within the initial 10 day line test at the beginning of your connection date

You can also call the ISP and ask them to reset the line and begin your 10 day line test again

It's always connected.

Well only when it gets flakey. otherwise, it's connected.

Still, if you are rebooting the modem every day, its going to seem like there is a problem with the line

My modem hasn't been rebooted in months

Anyway, that's how it works here, so if you are getting a low connection sync, don't reboot it and see if it settles itself after a couple weeks

I attached some screen shots. The only thing that says DOCSIS 2.0 is upstream apparently. Other than that stuff, I am not sure if anything is wrong

Not sure about your screens, US looks different to UK comparing it to my modem stats

Check what speeds you should be getting on 3.0 and 2.0 and take a speedtest to compare them

Hehe, NOTHING is wrong there. Upstream is generally always D2:

Check that one out which is in D3 mode (since multiple upstream channels) but still shows D2 for the individual channel or even 1.1!!! :o . You are trying to fix what's not broken. :pinch:

Why do you have to reboot the modem though? It just gets so slow that rebooting it is the only fix or what?

Yes everything slows down or it just stops working. A reboot fixes it everytime.

      I use it by choice but only for specific tasks that I have forgotten and it's quicker to ask then spend time wasted finding a decent answer on Google or coding a certain language. I prefer to use it. I do think that as it gets integrated into everything, when we eventually fully rely on it, I'm talking new gens not older gens like me, that we won't think for ourselves, I mean we will become lazy thinkers, lazy logical answer to problem which will go badly. But if we don't become fully dependant, we might be OK but I don't think personally we are going to be OK, not for the newer generations. Unless they advance in that space to the next level of intelligence where it can work out its own problems and create ideas for itself.

    • O&O ShutUp10 3.1.1104

      By Copernic · Posted

      O&O ShutUp10 3.1.1104 by Razvan Serea O&O ShutUp10 offers a simple yet effective way to take control of your Windows privacy. It provides access to almost 50 privacy-related tweaks, most of them hidden or not easily accessible to the average computer users. Using a very simple interface, you decide how Windows 10/11 should respect your privacy by deciding which unwanted functions should be deactivated. Using ShutUp10 you can easily disable Windows Defender, turn off telemetry, disable peer-to-peer updates, turn off Wi-Fi Sense, disable automatic Windows updates, turn off and reset Cortana and more. ShutUp10 allows you to create a System Restore point before you apply any changes, so that you can revert your system at any time if you run into problems. O&O ShutUp10 is entirely free and does not have to be installed – it can be simply run directly and immediately on your PC. And it will not install or download retrospectively unwanted or unnecessary software, like so many other programs do these days! O&O ShutUp10 Free and Premium The latest version brings O&O ShutUp10 Premium, expanding the app’s long-standing privacy controls with automatic enforcement of user-defined settings. Instead of manually rechecking options after every Windows update, users can set their preferred privacy configuration once—or apply recommended settings in a single click—and the tool continuously monitors them in the background. If Windows 10 or 11 re-enables disabled features or introduces new data collection paths, Premium restores the chosen settings automatically without user intervention. The free version remains available and fully functional for manual adjustments, offering the same core privacy controls for Windows. However, the Premium tier is aimed at users who want long-term, hands-off protection, adding automatic reapplication after updates, ongoing monitoring, and optional notifications to ensure privacy settings remain consistent over time. O&O ShutUp10 3.1.1104 changelog: Added “Show Differences” button in the overview panel “Don’t show again” option for the restore point prompt Ctrl+F keyboard shortcut for search/filter functionality Detection and linking of system-wide and user-specific setting associations Automatic search while typing PREM: Option to preserve notification counters and timestamps across application restarts PREM: Reset blocked settings button in the Settings dialog PREM: Informational message when no settings are blocked PREM: Update check can also be triggered from the menu PREM: Notification deduplication and activity log summary feature Improved L005 “Disable Windows Location Service”: Version-specific split (up to Windows 11 23H2) and new variant for Windows 11 24H2+ L001 (Disable Location): Added Night Light warning to the description in all languages Search now detects setting IDs even when ID display is disabled and offers to enable it Detection and removal of Copilot/AI desktop apps in RecallTerminator Optimized High DPI support PREM: Reset button is now only enabled when blocked items exist – setting IDs are shown in the confirmation dialog PREM: Updated tray icons with higher-resolution versions PREM: Activity Log timestamps now use localized date and time formats PREM: Tray icon status now uses OK/Warning indicators and localized tooltips PREM: Recall folder detection switched to service-based detection PREM: Copilot uninstallation now provides UI feedback and improved verification Fixed Description text was not displayed correctly for the last item and disappeared when clicking the scrollbar Crash when clicking a search result heading or the […] button PREM: Installation path is now correctly preserved during upgrades PREM: Tray icon was not reliably removed when exiting the application PREM: Main window was not displayed correctly in single-instance mode PREM: Incorrect display of the & symbol in tray icon tooltips on Windows 10 PREM: Fixed notification flooding after sleep/standby PREM: Dashboard was not refreshed after applying recommended settings during onboarding PREM: Progress bar was not reset after deleting Recall folders PREM: Fixed service startup failures PREM: Fixed incorrect drift detection when Automatic Protection was disabled PREM: Notifications now correctly count all deviating settings when protection is enabled PREM: Registration Wizard was shown after sleep/standby despite a valid license Download: O&O ShutUp10 3.1.1104 | 76.4 MB (Freeware) Download: O&O ShutUp10 32-bit | ARM64 View: O&O ShutUp10 Home Page | Screenshot Get alerted to all of our Software updates on Twitter at @NeowinSoftware
