If your Internet Service Provider (ISP) is Time Warner Cable (TWC), you have the option to either lease the cable modem or buy your own. If you buy your own modem, you can save $5.99 per month in monthly fees. However, you need to buy a modem that is approved by TWC. There are many modems on their approved list.

Motorola SBG6580 is one of the approved cable modems. It is a good modem that has WiFi capabilities.

Why is my Motorola modem not working?

If you have worked with computers, you probably have heard of the basic troubleshooting tip that someone has given to you. If you have an issue, reboot your computer.

The same situation applies to your cable modem. It’s possible there is an issue with the software inside the cable modem. By rebooting the modem, it’s the fastest way to fix your issue.

To reboot your modem, unplug the power cable from the modem, wait 10 seconds, and then plug the cable back in. Once you see all the LED lights are solid and not blinking, power cycle all the affected client machines.

Intermittent Issues

You may experience intermittent drops in your wireless connection with this modem. It is not due to TWC (though they have their fair share of issues :-). If you directly connect your computer to the modem, you will notice that the intermittent drops disappear.

Your wireless issues with the Motorola SBG6580 is due to the WMM setting. WMM is a wireless network feature of routers that allow you to prioritize different types of traffic (QoS). WMM support helps with different kinds of traffic such as voice over IP (VoIP), video applications, and streaming media. If you live in a crowded Wifi neighborhood area, it is generally not a good idea to turn on this feature. You will experience intermittent signal loss.

To turn off WMM support, connect your computer to the back of the modem. Open a web browser and type in the address bar. For default login, username is admin and password is motorola.

WARNING: You should change your password. For security reasons, don't leave it as the default unless you want to be hacked.

Click on the Wireless tab at the top of the menu. Click on WMM on the left side of the control panel. On the right side, specify the following settings:

* WMM Support: Off
* No-Acknowledgement: Off
* Power Save Support: Off

Your changes should take effect immediately.

How do I reset my Motorola SURFboard SBG6580?

If the troubleshooting steps above don’t work, you can do a factory reset of your modem. This will reset your custom configurations to the factory defaults.

To do the reset, find a small pinhole in the middle of the modem. Get a pen or paperclip. Carefully insert the tip of a pen or paperclip into the reset switch hole. Press and hold it for 10 seconds and release it. The LED indicators should turn off when you do it.

After this is done, connect your device to the modem again and see if it works now.

How do I know if my Motorola modem is bad?

The signal lights on the front of your Motorola modem should be solid if they are working properly. If the power light is off or blinking, there may be a problem with the power supply.

If the receiving light is off or blinking, your modem isn’t receiving the data properly. Contact your ISP for any network problems in your area.

If the sending light is off or blinking, your modem isn’t sending the data properly. Same as above, contact your ISP for any issues.

If the online status light is off or blinking, your modem is connected but something is preventing you from getting online. Check with your ISP.

If the activity light is off or blinking, there may be an issue between your modem and your computer.

Get a Router

If you have tried all the above steps and nothing seems to help, it is time to get a router. This cable modem does WiFi but it’s not the best. If your coverage involves a larger home, one cable modem may not be enough.

Using a mesh router may be a better option. Take a look at the Google Wifi. This is very easy to install and the user interface is very friendly.
