Ways to Improve Your In-Home WiFi Network

Details

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 recommendations to improve your WiFi.

Equipment Placement

Place your WiFi modem, wireless extender, or router in a central location in your home away from interference from metal objects, mirrors, microwaves, and cordless phones. For example, an optimal location may be on the second floor of your home, keeping the WiFi equipment up high and unobstructed.

Security

Having a secure in-home WiFi network can prevent others from connecting to your WiFi, stealing bandwidth, data, and reducing internet speeds. The recommended setting is WiFi Protected Access II (WPA2) and is the best security available. WPA2 is required for 802.11n and 802.11ac WiFi standards. Refer to Ways to Secure Your Wireless Network for more information.

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

Compatible Equipment

Slow speeds can be the result of having an older modem. Make sure you have the right equipment by checking Cox Certified Cable Modems. Below are some recommendations to improve your experience.
 

Topic Suggestions
Choosing the right modem or router
  • A DOCSIS 3.1 modem is required to deliver Gigablast over DOCSIS, and recommended for the Ultimate Internet package.
  • For Gigablast customers who are using a separate router, a Gigabit-capable router is required.
  • DOCSIS 3.0 modem is required for all Internet packages other than Gigablast.
  • Refer to Cox Certified Cable Modems for more information.
Dual band WiFi modems and routers

The primary differences between the 2.4 GHz and 5 GHz wireless frequencies are range (distance) and bandwidth (speed).

  • 5 GHz provides faster Internet at a shorter distance, whereas 2.4 GHz offers coverage for farther distances, but may perform at slower speeds.
  • If you think about 5 GHz like a highway, it’s like having more lanes and less traffic on the highway – so you can go faster!
  • You will first need to ensure that devices, such as tablets, smartphones or laptops, can read the 5 GHz Network. If the device is dual band-capable, you should see two SSID / Network names; one with 2.4 or 2.4 GHz, and another labeled with 5G or 5 GHz.
  • 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, the 2.4 GHz is recommended.
  • If you are renaming your Network SSID, make sure to select a different and unique name for each WiFi network that helps you clearly identify both the 2.4 GHz and the 5 GHz network.

    Note: If you are using the Technicolor CGM4141, only one SSID/Network name is available for both networks.
     
  • The optimal channel setting for each wireless network is automatic, or auto. Auto allows the WiFi Modem or router to select the channel with the least amount of congestion.
Internet devices

Are your internet devices a few years old? As wireless technology advances, the speed and wireless performance of new devices continue to improve. Using older technology, such as a laptop, tablet, or other devices, can slow down performance of all the devices on your network.

Using Panoramic WiFi Wireless Extenders

Panoramic WiFi uses a WiFi modem and optional wireless extenders in different locations in your home to ensure wall-to-wall WiFi coverage. Devices such as smartphones, tablets, and laptops usually switch automatically to the closest WiFi modem or wireless extender. If they don't switch, then devices may experience weak WiFi signal and issues with connectivity or slow speeds.

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.
