Motorola SBG6580If 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.

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 192.168.0.1 in the address bar. For default login, username is admin and password is motorola. You should change your password in the future. 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.
