View the following frequently asked questions about Cox In-Home WiFi.

What equipment should I have for the best Internet experience?

Cox only recommends and provides certified DOCSIS 3.0 equipment to ensure the best and fastest Internet experience, and provides the latest in WiFi technology.
DOCSIS 3.0 is the very latest Data Over Cable Systems Interface Specification (DOCSIS), and includes many new, advanced performance-enhancing features that are not available on DOCSIS 1.0, 1.1, or 2.0 devices. See the Cox Approved Cable Modems.
To learn more on how to optimize your speeds and WiFi network, see Ways to Improve Your In-Home WiFi Network.
If you are purchasing WiFi equipment, 802.11ac Dual Band is recommended.

Why am I not getting advertised speeds on my WiFi network?

Cox High Speed Internet advertised speeds are based upon a direct connection to the Internet or phone modem. Actual performance will vary, depending on many factors, including interference with other wireless devices, the amount of bandwidth others are using, and obstructions such as walls between you and the wireless router. Other factors could include the following.

  • Your WiFi client, such as computer, tablet, printer, mobile device, Smart TV, distance from the router or gateway.
  • Obstacles between your WiFi client and router / gateway.
  • Your WiFi network security type.
  • Your WiFi client equipment type (802.11b / 802.11g / 802.11n / 802.11ac).
  • The number of simultaneously connected WiFi clients.
  • Normal WiFi interference from other wireless networks or non-WiFi wireless devices in the area.

How does my In-Home WiFi Network affect my Internet experience?

A wired Ethernet connection always provides the fastest speeds. But in today's wireless world, it is important to know how to optimize your In-Home WiFi Network to achieve the best speeds and connectivity.
To learn how to optimize your In-Home WiFi Network, see Ways to Improve Your In-Home WiFi Network.

What technology should I use for the best performance?

The most common WiFi specification in use today is 802.11n, which can operate in both the 2.4GHz and 5GHz RF spectrums. Some WiFi client devices may only use one, with 2.4GHz single band devices being the most common. The latest technology of 802.11ac is also quickly becoming available in many devices.

It is very important to make sure to operate your router or gateway in the RF spectrum that is compatible with your Wi-Fi client devices, 2.4 GHz or 5 GHz.

  • If you have 802.11g or 802.11b client devices, you will want to make sure to use 2.4 GHz.
  • If you have dual band 802.11n client devices, then you may choose either SSID, 2.4 GHz or 5 GHz, from your dual band router or gateway.
  • If you only have a single band router or gateway, then you will need to use the 2.4 GHz band.

It is also important to understand that older legacy WiFi client devices using 802.11g or 802.11b can in fact slow down the wireless network for everybody. When possible, try to only use 802.11n client devices to optimize your wireless network’s performance.

Why is security important to speeds through my WiFi network?

Security is important for securing and encrypting the connection between your router or WiFi modem and your wireless WiFi client so that unauthorized persons cannot use your bandwidth and slow your speeds. The type of security you choose is important to maximize your wireless network’s performance.

Today, the only IEEE and WiFi Alliance approved WiFi security method is WPA2-PSK (AES) security, and it is the security encryption method that provides the best performance on your network. Some very old WiFi client devices may not support this method, so be aware if you must choose older security methods like WEP or WPA-PSK (TKIP) your wireless network performance may be degraded.

Is the location of my WiFi modem or router important to my wireless speed?

Yes, the location of your WiFi modem or router is important to your wireless speed. The farther your computer or other device is from the router, the slower the speed of your Internet service. It is always best to place the WiFi router or modem in the center of the area you wish to cover, and as elevated as high as possible. This will provide for the maximum wireless coverage possible to the highest number of client devices.

If you are having difficulty connecting wirelessly to your router in some instances or only getting a low Mbps wireless link to your client, it might be best to move your router or gateway to a more centralized and elevated area, or consider installing a wireless repeater or range extender to provide additional coverage in areas near the coverage border.

What is the recommended distance between household appliances and my In-Home WiFi device?

Cox recommends the following distances between household appliances and your In-Home WiFi device.

  • Microwave ovens - approximately 40 feet
  • Baby monitors - approximately 20 - 40 feet
  • Cordless phones - approximately 20 - 30 feet
  • Bluetooth® devices - approximately 20 feet

Is my speed affected by the number of devices that are connected to my WiFi network?

Most wireless routers and WiFi modems today do a good job of managing normal residential simultaneous wireless connections. However, your wireless network’s bandwidth is shared with each device that is connected to the Internet.
