A complete guide on fixing Arris not connected to the internet

Check the Internet connection 

The first thing to check if your Arris modem is not online for several causes is your internet connection. 

You need to ensure that your internet connection is working properly and there are no dropouts on your internet service provider's end. 

Also, you should inspect wires, cables, and connections and check your internet connection by connecting another cable to the ethernet cable.

Check if your internet has a connection

This way, you can see if something needs to be fixed on your end or if something is wrong on your ISP's end. 

Thus, if your Internet is not operating properly, you should contact your ISP. If not, you should start troubleshooting with the following steps:

Power cycle the modem

Power cycling an Arris modem can draw all electricity from your device and perform a cold boot for later startup. 

Follow the simple steps below when you don't know how to power cycle it:

• Step 1. Power off the Arris modem. 

• Step 2. Wait a moment for the device to cool. 

• Step 3. Disconnect the power provider from the source. 

• Step 4. Reconnect the power adapter and turn on the device. You can also connect your modem to another source to avoid possible malfunctions with your current power supply.

Power cycle your modem

Restart your modem

If your modem isn't working properly, or you accidentally messed up your settings, the best solution is to restart your modem. 

This is one of the simplest ways to fix the problems of multiple electronic devices. 

The modem should be turned off and then on again and left off for 1-2 minutes. Unplug the power cord from the power source or modem's back. 

Make sure all LEDs are off, wait 1 minute, then reconnect the power cord to the modem. Wait until the Internet light turns green, then try connecting to the Internet again. 

It's also important to make sure the power outlet your modem uses is working properly. 

It then reboots and restarts all hardware and software components and triggers an attempt to reconnect to the internet. 

All issues are resolved this way and the Arris modem is online in no time.

Reset your router

Another solution if the Arris modem is not ready to online is to completely reset the system.

Note that resetting the modem can restore all default settings, which means that all custom settings including Wi-Fi settings can be completely lost.

So if you find a bug in the software, or the router settings be the main cause of the modem to go offline, a system reset will fix it.

You may reset your router online or using the hardware button. Because doing it with buttons is much faster.

Reset your router 

• Step 1. Power your router on. 

• Step 2. Find the small reset button near the restart button. 

• Step 3. Hold for 15 seconds. 

• Step 4. Release the router's button after you power the router off, and wait for a few minutes. After a few minutes, your router will fully reset. Check if the problem still persists. 

• Step 5. Wait a few seconds for this process to finish, then reboot your system. Then set up your model on your device and connect to the internet network. 

Troubleshoot cable connection

The next solution is to ensure all cables to and from the Arris modem are properly connected. 

The most ethical approach if you are concerned about cable failure is to test the cable. 

If you have another modem set up on your home router, it's pretty easy to swap cables and see if it works. If not, you can:

• Step 1. Remove the power adapter and Ethernet cable by unplugging them  from your modem. 

• Step 2. Look for log time errors, hardware damage, or pressure scratches. 

• Step 3. Swap both ends and reconnect the Ethernet cable. 

You must connect the Ethernet cable between your modem and router to one of the yellow ports on your router and a single Ethernet port on your modem. 

It's hard to connect wrong, but double check that it's correct before proceeding.

Troubleshoot cable connection

Avoid overheating

If your device is overheating, you may experience internet failure. 

Below is the detailed guide you may use to protect your modem from overheating.

• Step 1. Keep your modem in a dry and well-ventilated place. 

• Step 2. Double check if the router is standing on a heat conductor. 

• Step 3. Hold your router out of direct sunlight. 

• Step 4. Remove dust around the rear vents. 

After completing all these steps, power the modem on for about 30 minutes and touch the side cover to see if it is overheating.

To reset DNS, follow these simple steps: 

• Step 1. Open the Start menu and choose Network Connections. 

• Step 2. Click an option to change the adapter.

• Step 6. When finished, click OK to confirm the action and exit.

After this process, the system will be back online. 

After connecting your modem to the internet again, run a WiFi speed test to ensure you're getting good internet speeds.

You must run tests on multiple devices. If the issue persists, continue the next method.
