There are several reasons why your Cox modem might be blinking blue, including hardware problems, memory leaks, and power flow problems. Fortunately, Cox is willing to replace the modem for free if you can prove it’s an issue with its hardware. The internet is vital for many people, so any interruption in service is a big inconvenience. Here are some ways to fix your problems.

Problems with DNS cache

If you’re having trouble connecting to the Internet or experiencing slow upload and download speeds, you may be having problems with the DNS cache. To fix this, try to reset your Cox modem by pressing and holding the reset button on the device for at least eight seconds. If this does not work, contact Cox technical support to find out what’s causing the problem. A service outage is an issue that may not be related to the DNS cache, but you may want to try contacting the ISP directly.

If you’re receiving the ‘DNS server is not responding’ error, you may have several issues causing this problem. First of all, make sure that you’re using a modern browser. If you’re using Google Chrome or Safari as your default browser, try using Mozilla Firefox or Microsoft Edge instead. If neither of these fixes your problem, you may have to try a different web browser.

IP address glitches

If you are frustrated by your Cox modem blinking blue due to an IP address glitch, you may need to reboot your device. You can do this remotely by logging into your account with Cox. Click on “Restart Device” and follow the instructions. Your modem should now be fixed. If it doesn’t, contact Cox to resolve the issue. The company will then try to troubleshoot the problem for you.

Upon contacting Cox customer support, you will be asked what type of connection you are using. While almost everyone nowadays has some sort of WiFi connection, Cox will blame your wireless router or wifi connection. But the reality is that it is your modem that is causing the problem. There are two common solutions to this problem. First, you can try resetting the network settings on your computer.

Weak WiFi signal

You can use your cox modem to increase your wireless signal. Sometimes, you will notice that your internet connection is not as strong as it usually is. This is due to the fact that Wi-Fi signals become weaker as they pass through solid objects such as walls. You can fix this by moving your device closer to the router. Another way to improve your Wi-Fi signal is to use signal boosting devices.

The first step in solving this problem is to try to determine where the problem lies. If it is the modem, try using a device that is near the router or move it to a more centralized location. If nothing works, invest in a WiFi booster. In some cases, the problem is due to an overloaded network. In such cases, you can contact Cox support to run diagnostics on your modem.

Firmware update

Sometimes, your Cox modem is not working correctly because of a software or hardware malfunction. Luckily, you can fix this easily, as long as you can remember a few common Cox modem light colors. Read on to learn how to update the firmware on your device and troubleshoot common Cox modem light problems. You may even be able to reset your Cox modem remotely.

First, power down your Cox modem. You may have disconnected your cable wiring, or your device has overheated and can no longer establish a downstream connection. If this happens, restart the modem by unplugging it from the wall for at least one minute. If that doesn’t work, call Cox customer service and get it fixed. It will be able to diagnose the problem for you.
