14 Ways to Fix Arris Router WiFi, not working Problems

Here we have listed the Best Ways to Fix Arris Router WiFi, not working Problems.

Use the correct channel (band) on your router

Usually, it’s either 2.4 or 5 GHz. If everyone’s routers run on the same frequency band, you’re likely to get interference. There should be only one wireless signal in your home; if you have multiple, change the channel to avoid interference or the “arris router 2.4Ghz not working” problem.

This means that your Arris router isn’t powerful enough to transmit on an overcrowded band with all those other routers.

Don’t set the router to the “Auto” channel.

Most routers pick a channel for you, but that can cause interference with your neighbors’ routers.

You should pick one to reduce interference across the entire network, not just in your house!

Remove Physical Obstruction blocking your Arris Router WiFi Signal 

Physical appliances also operate on the same frequency as your arris router WiFi. Massive metal objects are very bad for Arris routers

If you can move your router to another room, do it. Sometimes, you can get a better range with some non-metal obstruction on top of or around it, but if possible, remove tanks, refrigerators, microwaves, etc.

Replace your Router Antenna 

Antennas can get old and stop working correctly.

If you’re having signal issues, try replacing them with higher gain ones or new ones made for your router.

Turn off Encryption / Security:

Some older routers have security settings that don’t allow some newer devices to connect (this caused the “arris router not working” problem once).

First, you should turn it off and see if that fixes your Arris router WiFi connectivity issues. Don’t use security on the Arris router anymore if it does!

Change Wireless Encryption 

If switching off encryption doesn’t work for you, change your wireless encryption type to WPA2. It’s the most compatible option for your router, whereas WEP is deprecated mainly and often causes “arris n300 router not working” problems.

Wired Ethernet connections are more secure than wireless ones, so don’t rely on them exclusively!

Buy an Ethernet Extender if Wired Connections Don’t Work 

If you have problems getting a wired connection, an ethernet extender or switch can help. Just plug them in when you’re connecting via Ethernet, and they’ll help extend the signal!

Upgrade Firmware 

Some firmware versions have bugs that cause “arris router WiFi not working” issues. So try upgrading the firmware to the latest version! Firmware is the “software” that runs your Arris router. It’s like the OS on your computer, and having bugs means it isn’t working correctly, which makes your Arris router not work.

Turn off QoS 

QoS manages the quality of your internet connection and can be interfering with your WiFi signal if turned on or set up incorrectly.

Re-position Your Router 

You can’t constantly move your router; sometimes, it’s just in an awkward spot in your house. If you can, try moving it or re-orienting its antennas, so they are aligned differently to get a better connection.

Limit the number of devices 

This is an old-school way to get better internet speed, but still very effective. “Arris modem no WiFi” issue is another common problem. Sometimes resetting your modem can help you to solve the issue.

If it persists, limit the devices that connect via WiFi, so others have to use Ethernet instead of slowing down your router!

Upgrade Your Internet Cable or DSL Line

If you are the only one with the “arris router keeps rebooting” problem, try calling your internet provider and ask for a higher speed.

If others in the house aren’t having any problems, but you are, call and see if they’ll give you a new line too! And If it fixes your issue, upgrade to faster internet or install more lines.

Change your DNS 

Changing your Arris router WiFi settings can fix “arris n600 WiFi” problems or connectivity issues in general!

If you’re going to change anything, change it before you connect, and don’t forget that you must give the IP address of the new DNS server to your Smart TV or Blu-Ray player.

Change the IP Address of Your Router 

Another solution is changing your router’s IP address, which you can do by connecting to it via Ethernet and entering some commands in a new terminal window on your computer. If none of this works for you, contact Arris support!
