Ways to Improve Your In-Home WiFi Network


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 Network to achieve the best speeds and connectivity. Improve your In-Home WiFi Network with the following recommendations.

Equipment Placement

Setting up your In-Home Network begins with proper placement of your WiFi Modem or router. Select a central location within your home away from interference such as metal objects, mirrors, microwaves, and cordless phones. If you can, relocate your equipment to an optimal location on the second floor of your home, keeping it up high and unobstructed.


It is important to ensure your in-home network is secure to ensure that others are not connecting to your network and stealing bandwidth, which reduces your speeds. Cox WiFi Modems are pre-configured with the ideal WiFi and security settings. If you do not have a Cox provided WiFi Modem, you can verify your in-home WiFi security settings to make sure it’s secured by using the following information. If your network is not secure, you can enable the network security to keep others from accessing your network and data.

Recommended Security Settings

The recommended setting is WPA2 which is WiFi Protected Access II. WPA2 is the best security available and is required for 802.11n and 802.11ac WiFi standards. Additionally, WPA2 is strongly recommended to achieve the fastest speeds possible.For additional information about securing your network, refer to Ways to Secure Your Wireless Network

Other Security Settings (Not Recommended)

There are older encryption types such as WEP. WEP means you have Wired Equivalent Privacy, which is an older type of encryption that is less secure than WPA or WPA2. Cox recommends that you upgrade your router to WPA2.

Compatible Equipment

Make sure your Internet equipment is compatible to give you the speeds you need. Additionally, older equipment may cause you to experience slower speeds. To ensure an optimal experience, make sure you have the right WiFi Modem or Router. Here are some recommendations to improve your experience.

Choosing the Right Modem

A DOCSIS 3.0 modem is necessary to achieve speeds higher than 25 Mbps.

Understanding the Difference Between 2.4 GHz and 5 GHz

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 your devices, such as tablets, smartphones or laptops, can read the 5 GHz Network. If your 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.
  • If your devices can take advantage of this, use 5 GHz 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.

Device Age

Are your devices that are accessing the Internet a few years old? Older technology on even a single device can slow down performance of all devices on your network. As wireless technology advances in new devices, the speed and wireless performance continues to improve.

For example, look at the difference illustrated below between the 2012 MacBook Air and the 2013 model. Wireless speeds are more than 3 times faster. Devices with 802.11g such as laptops running Windows XP or older generation iPods have even slower performance.

Channel Selection

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.

Tips for Panoramic WiFi Customers with Wireless Extenders

Panoramic WiFi from Cox offers wall to wall coverage throughout your home with the use of a premium services WiFi modem and optional wireless extenders. Both the WiFi modem and the wireless extenders emit WiFi signals from different locations within your home. In most cases, mobile devices such as smartphones, tablets, and laptops switch automatically to the closest WiFi modem or wireless extender; however, occasionally your device may stay connected to one and not switch automatically to the closest modem or wireless extender. If this occurs, your mobile device may experience a weak WiFi signal which can lead to issues with connectivity or slow speeds.

If you experience this issue, complete the following.

  • Move the mobile device close to the premium services WiFi modem or wireless extender you wish to connect to in your home.
  • Go to the Settings menu on your device and turn WiFi OFF and and then back ON.

This will trigger your mobile device to connect to the closest WiFi modem or wireless extender.
