Cable Modem Rebooting Constantly (Reasons + Solution)

No idea what to do about the Cable Modem Rebooting Constantly every two minutes? There are various reasons why your primary networking suddenly seems to be malfunctioning. Connectivity issues, bad firmware, poor cabling, or throttling are all possible causes of this problem.

Is there cause for concern? I haven’t covered everything here, but I have addressed all of the essential issues surrounding frequent modem resets and the solutions that go along with them. And certainly, the remedies to most of these issues are straightforward.

Cable Modem Rebooting Constantly

It’s important to have a clear picture of what a reset looks like before diving into the details of the problems. LEDs glow green, and the downstream and even upstream indicators flash wildly when a modem resets. As soon as you press “reboot,” you’ll see the device working normally again and just after a few minutes, making life incredibly difficult for a normal user to operate.

Why Is My Cable Modem Always Rebooting?

If your cable modem isn’t working properly, it will automatically reset itself. Modems reboot themselves after a reset so that you can get online again, and then they restart the process again. It’s not a pleasant experience, but there are several reasons.

The power connectors on your cable modem could be causing it to reset incessantly. Your modem’s power connection may be loose, causing it to reboot to fix the problem constantly. Performing a wiggle test on both the power supply and the connectors will reveal any loose connections.

If the modem is constantly overheating, that could be another reason for its erratic behavior. If you see your router’s temperature rise to 115 degrees Fahrenheit or higher, it’s overheating. It is recommended that you use a fan-cooled modem if yours does not have one and that you leave some space between it and the wall so that it may breathe.

In addition, a constantly restarting modem is a sign of an overworked modem. There is a lot of work for the router when it has to allocate IP addresses to several devices at once. The modem’s processor can overheat, causing its software to slow down or freeze, making it difficult to use. An issue like this causes unpredictable restarts.

Why Modem Rebooting Constantly?

That’s a problem that must be addressed. Here are a few of the more prevalent causes of those inconvenient and time-consuming modem reboots. The good news is that each issue has a solution. It appears like Christmas has come early this year!

Modem Overworking

Problem: Your modem’s performance can become sluggish and unpredictable if you spend all of your time working. Your modem may start acting up by regularly resetting for days, weeks, or months.

Solution: Unplugging the modem, waiting a few seconds, and then connecting it back in is the best way to fix this easily fixable problem. If this doesn’t work, you can always physically reset the device to apply the permanent remedy.

Hardware Issues

If your modem frequently resets due to faulty hardware or any other internal problem, you may need to use an alternative approach. A simple solution is to use the modem’s warranty if it’s still reasonably fresh. Otherwise, you’ll have to buy a new modem to get out of this rut. Check out my modem-buying advice to get the greatest fit for your needs.

ISP-Ridden Issues

It may no longer be a modem-specific problem when the cable modem continues resetting. Instead, a shaky connection may result from a problem with the ISP’s network.

The only option to get rid of the problem is to contact the ISP and see if a reboot call has been shared or not and then reconnect. The modem should be disconnected for some time and plugged back in only after the ISP completes or closes the repair detail.

Faulty Configuration

An issue may arise if the current modem setting causes you to be out of sync with your ISP. Many security issues arise when the modem is out of sync because of a defective set or because the modem has been running non-stop for a long period. Once the modem is rebooted, enter the web interface and re-configure it depending on your ISP’s details and other settings.

Bad Network

Unlike routers and access points, which rely on a clear line of sight for data transmission, modems receive packets directly from the Internet service provider. However, if your ISP’s internet service is unreliable or glitches, your modem may begin to act up and reset itself often.

Remove anything that may be obstructing the coaxial cable. Additionally, if this is not the case, you should connect to your ISP and evaluate the connection’s speed and reliability.

Overheating

Overheating might cause your modem to malfunction, even if it is properly installed and connected. Overheating can cause throttling and other hardware issues, even if it seems inconsequential to some users.

Modification: Modems are designed with heat dissipation in mind. As a result, overheating can occur if the vents aren’t properly cleaned and become clogged. As a result, you must clean the ducts and place the modem in an area with appropriate ventilation before proceeding forward.

Loose Wires

Loose cables and wires, which are more of a hardware problem, can go undiscovered for lengthy periods. You may want to tighten the coaxial wire if it hasn’t been correctly fastened after trying all the other suggested methods. A simple fix for slack cables is to double-check their connections and tighten them up if they aren’t already.

Faulty Firmware

Modems and other active electrical devices contain built-in firmware that can become out-of-date and obsolete. As a result, a broken modem may repeatedly force the device to reset itself.

Solution: Applying the most recent security patches to the device’s firmware can help resolve this problem. In addition, you must make certain that the modem receives performance updates to eliminate any software issues.

Network Issues

In the case of multiple devices connected to the router, which places undue strain on the modem, data packet loss is possible as part of the greater network problem scenario. Alternatively, network problems may result from too much congestion, in which case your modem will become overworked.

Alternatively, it might be a typical DDoS attack or any other network security issue that could damage the modem’s well-being, making it unresponsive or constantly resetting a well-configured attack.

The only option to fix network problems is manually resetting the modem to its factory settings. Once the modem has been hard-reset, all existing firewall settings, port configurations, and DNS settings have been wiped clean.

Once the lights start flashing and other indicators become green, you can use a paperclip to hit the reset button on the back of the router until the lights go out. You can then use the web interface to set up the modem properly after being reset manually.

Why Is It Necessary To Reset Modems?

Your computer’s modem performs many intricate activities to ensure that you get the best possible data service. So that the correct information is delivered to the right computer at the appropriate moment. The process is also made as efficient as possible, thanks to this.

However, you may discover that the modem, like the computer, lasts considerably longer. This means that at some point in time, it will no longer be able to send information as quickly as it should or will begin to slow down its operations. It will ask you to reset it if this occurs, and once you do, it will resume working.

Many electronic devices are not meant to be constantly running. In addition to the modem, removing it from the power cord and then plugging it back in is the best way to ensure it operates for a long time. Your computer’s internet and wireless performance will be improved due to this procedure. “

The DOCSIS and GPON technologies for internet access delivery over coax cable and fiber optic cable are what you need to use your modem to connect to the internet. End-users are typically represented by several points that receive and transmit internet traffic from a single point of origin. The DOCSIS and GPON will tell each end-user how much time they have to upload their data and when they should do so.

Conclusion

For a variety of reasons, you’ll face Cable Modem Rebooting Constantly. You do this to ensure that it is working properly, particularly in terms of speed. To be on the safe side, make a backup of your data before deciding to reset your phone. However, the best thing to do before resetting the cable modem is to make sure that you intend to reboot or restart it.
