How To Fix Arris Modem Ethernet Port Not Working?

Ethernet ports are the components responsible for establishing that kind of connection. Even though many users prefer wireless connections, due to their easier installation and lack of accessory components, such as cables, many users opt for Ethernet connections. 

That is because, even though the Ethernet connection does not enjoy the multiple connection aspects a wireless connection does, it delivers higher stability. Also, the latest Ethernet connection technologies have enhanced the speeds of connections by more than an arm’s length.

With new technologies of Ethernet cables, users can even navigate faster than with most wireless connections, which makes the first a more attractive option for high-end users. When we say high-end, we mean streamers, gamers, or users who frequently transfer large files.

So, if you are amongst these users, the latest Ethernet connection technologies should deliver the best performance. However, if you are having problems with the Ethernet ports of your Arris modem, here is what you should do to fix them:

1. Make Sure Cables and Connectors Are in Good Condition

Cables and connections are as important to a proper connection as the signal itself. Most people don’t regard these components as so important, though.

In the end, they mostly find out their connections should be delivering much higher levels of performance with proper cables and connectors. Don’t make that mistake and inspect these components every now and then.

Not only their conditions, since damage to the cables or connectors are not the only aspect that can affect an Ethernet connection, but also if cables are properly plugged into the correct ports.

On the other hand, if you do notice any sort of damage to any of the cables or connectors, make sure to get them replaced. Apart from being one of the cheapest components of an Ethernet connection, repaired cables rarely deliver the same level of performance as new ones.

In the end, you might spend money fixing them and still get the same results, but with a reduced lifetime. That means you will end up having to get replacements anyway.

In order to check the condition of the Ethernet cable, simply attach it to a different device and run a connection test.

In case the connection with the second device works as it should, then the cable is indeed in good condition. If not, get it replaced as soon as possible. Connectors, however, can be a little trickier to check, as they also have an inside part that requires opening up the device.

So, if the connectors are not displaying any visual signs of damage, make sure a professional checks the inside part, unless you know exactly what you’re doing. Also, the attempt from the user might void the warranty and end up costing more.

2. Make Sure the Ethernet Port Is Clear

It might happen that, due to the absorption of carbon particles, the metal connectors in the Ethernet port may lose contact with the cable. This will definitely lead the connection to suffer performance drops, so make sure the connectors are clear.

If you notice they are not as clear as they should be, get a soft brush or cloth and use some alcohol or CTC to clear them. We strongly recommend you clean with extreme care, as the components might be damaged, and the Ethernet port may have to be replaced.

So, in case you don’t feel able to perform the cleaning, make sure to get professional help. They may even have easier ways to clear the metal connectors than the DIY solutions you may find on the internet.

3. Give The Modem A Restart

In case you inspect the cables, and connectors and make sure the ports are not obstructed but the Ethernet port is still not properly working, your next move should be to restart your Arris modem. Many so-called experts do not consider the restarting procedure an efficient problem-solver, but it actually is.

Not only does the procedure clear the cache from unnecessary or obsolete temporary files, but it also addresses minor problems the device might have regarding compatibility or configuration aspects.

Additionally, by restarting your Arris modem, you are giving it some time to breathe, which normally bears good results as well.

So, go ahead and unplug it from the power outlet and let it rest for at least a minute or two before plugging it back in. Then, let it go through the booting diagnostics and protocols before running the connection tests. That should do it and your Ethernet port problem is likely to have been fixed with this simple solution.

4. Get To Arris Technical Assistance

In case you try all three solutions above and the problem with the Ethernet port of your Arris modem persists, there is one last easy move for you to make. Most users are not specialists and they might not be as acquainted with the range of problems a device may experience as trained professionals.

Therefore, seek their professional help and let them check your Arris modem for whatever may be causing the Ethernet port not to work properly.

Dealing with a variety of problems gives technicians a broader view of the situation and a higher knowledge of what could be causing the Ethernet port issue. Also, they have the proper equipment for the testing and repairing of whatever problem the device may be experiencing.
