5 Ways To Fix Suddenlink Modem Not Working

With many of us being so heavily reliant on the internet for a wide variety of tasks these days, it can be a massive inconvenience if it drops out for even a minute or two. Considering that many of us do our banking online and even work from home using it, it really is unacceptable to tolerate a less than optimal service. 

Sadly, there are many of us out there who experience these kinds of issues on a regular basis. Though we would rate Suddenlink as one of the better services out there, this doesn’t mean that users of this service are immune to experiencing these kinds of problems. 

However, the problem that you are experiencing if you are reading this isn’t too much to be worried about. 

Having trawled the boards and forums to see whether there were any good fixes out there for your Suddenlink Modem seemingly refusing to work, we were pleasantly surprised by how easy this one is to fix. 

So, even if you wouldn’t consider yourself all that ‘techy’ a person, you should be able to get back online pretty quickly by following the simple steps below. So, without any further ado, let’s get stick right into it so that you can get back to work or simply enjoying the net for your entertainment needs. 

How to Troubleshoot Suddenlink Modem Not Working

There are a few different reasons why you could be experiencing these kinds of issues at the moment. In nearly every case, they will be resolved by the time you go through all of these steps. So, let’s start with the easy stuff first and then work our way up through the more complicated fixes. 

1. Resetting the Network

With nearly every device you are having trouble with, the first thing you should think of is resetting it. In general, this is a great way to clear out any bugs that will have accumulated over time, restoring the device to optimal performance levels. 

All you need to do in this case is to unplug the power cable from the modem itself. While you are there, it is also a good idea to do the same to the router. In essence, you are looking to unplug any power cable that is in any way associated with the Suddenlink network. 

After you have taken care of all of that, simply leave them all unplugged for a minimum of 30 seconds. Once that time has passed, just plug them in again. And, believe it or not, that’s all there is to it. Though the process light seem a little odd if you haven’t done it before, it leads the system to completely reboot itself. 

As such, it will start performing much better than it has in the last while. In general, we would recommend doing this every now and then, even if everything is working okay. You should notice that it keeps your internet speed where it is supposed to be. For most of you, this should be the problem completely resolved. If not, it is time to move onto the next step. 

2. Check the Coaxial Cables

If the previous fix didn’t do all that much, it is likely that the problem could be related to the hardware. So, the most common thing to go wrong here is that a cable may have loosened or become compromised over time. This is particularly the case if you have been using your Suddenlink Modem for a while now. 

So, the first thing we need to do here is to unscrew all of the coaxial cables at both the wall and on your modem. Before screwing them back in again, have a close look to see if the needle in the cable is bent or damaged in any way. 

You should also check to make sure there is no obvious damage along the length of the cable too. What you should be on the lookout for is signs of fraying that will expose the innards. If you notice any of that, the only logical thing to do is replace the cable. 

If you haven’t noticed any damage anywhere along the lines, just put everything back where it was, nice and tightly, and reset the modem again. No damage will mean that this fix wasn’t what your modem needed. So, there’s nothing else for it except to move onto the next step.

3. Check the Ethernet Cables

If you are still having the same problem, the next thing to do is checking yet more cables. First, check that your Ethernet cables are in good condition. If nothing looks in any way damaged, take out the Ethernet cables that are connecting to the router or other related network devices. Now, try plugging the Ethernet cable directly into your laptop or PC. 

Now that you have a direct connection to the modem, reset the modem again and you should have effectively bypassed the router. Using this bypassing technique, it is pretty easy to then figure out what the problem is. By this we mean that if your internet is now working perfectly, the problem was with your router.

4. Too Many Devices Connected to the Modem

At this point, it is quite natural to become a little disheartened that nothing has worked. However, there is still a chance that he problem isn’t all that big or serious. It could just be the case that your modem is overloaded and can’t handle all of the devices that it is trying to run. 

Too many devices on any one network will cause the speed to slow right down, sometimes to the point where it will cease to function entirely. To prevent this from happening, always make sure that no more than three devices are taking bandwidth from the same source. 

5. Replace the Modem & Adapters

Unfortunately, if none of the first four tips have worked, the problem is likely to be much more severe than we had anticipated. At this point, the most likely causes of the problem are both the modems and adapters. If you think this may be the case, we would recommend that you consider replacing them entirely. 

Seeing as the Wi-Fi adapter is a cheaper component to replace, we would suggest you go that route at first. If that doesn’t work, it is time to replace the modem. Once you have done this, there is no good reason for any issues to persist. 

The Last Word 

Unfortunately, these are the only fixes that we could find that genuinely worked. Then again, we never like to exclude the possibility that one of our readers may have come up with a new and innovative way of fixing this problem.
