Improving Your In-Home WiFi


Need more help with your WiFi connection? Visit our In-Home WiFi Support page.

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 to achieve the best speeds and connectivity. Use the following steps to improve your in-home WiFi.

If you have a My WiFi-enabled modem, you can use the My WiFi portal on Cox.com to see information about your in-home WiFi network. Refer to Managing Your In-Home Network with My WiFi.


Ensure that your WiFi modem, wireless extender, or router is placed according to the following recommendations.

  • Centrally located in your home
  • Away from interference from metal objects, mirrors, microwaves, and cordless phones

An optimal location may be on the second floor of your home, keeping the WiFi equipment up high and unobstructed.

Verify your in-home WiFi is secured with WiFi Protected Access II (WPA2). Refer to Ways to Secure Your Wireless Network for more information.

Note: Cox Panoramic WiFi Modems are pre-configured with WiFi and security settings.


Using your device owner's manuals, ensure that your modem and router achieve your internet package speeds with the following information.

  • A DOCSIS 3.1 modem is required to deliver Gigablast over DOCSIS and recommended for Ultimate.
  • A DOCSIS 3.0 modem minimum is required for all internet packages other than Gigablast.
  • For Gigablast customers who are using a separate router, a Gigabit-capable router is required.

    Note: Refer to Cox Certified Cable Modems for more information.

Use the following recommendations to ensure your WiFi modem or router can achieve your internet package speeds.

  • Cox recommends dual band WiFi modems or routers.
  • Use devices that can connect to the 5 GHz network in close proximity to your WiFi modem or router.
  • If you are far from your WiFi modem or router, connect to the 2.4 GHz network.
  • Set your wireless network channel selection to automatic so the WiFi modem or router selects the channel with the least amount of congestion.
  • When using a router, make sure your Ethernet cord is at least a Category 5E (CAT5E) cable.

Check the age and WiFi capabilities of your internet devices to ensure they are updated and are not slowing down the performance of all the devices on your WiFi network.


If you are using Panoramic WiFi extenders, then use the following steps to manually connect a device to the closest WiFi modem or wireless extender.

  1. Move the device closer to WiFi modem or wireless extender you wish to connect to in your home.
  2. Go to the Settings menu on your device.
  3. Turn the WiFi OFF and then back ON.

    Note: Wireless extenders are not available with the Technicolor CGM4141 at this time.
