  Tips to Improve Your Home Wi-Fi Performance

Mar 31, 2020

In response to the Covid-19 outbreak, most people around the world are being asked to stay home. At the same time, they’re going about their daily lives as best as possible under the circumstances. This means that people will be doing more online such as working from home, classroom assignments, calling their friends and watching videos.

With more users in the home simultaneously active online, you may be experiencing Wi-Fi overload. Joanna Stern over at the Wall Street Journal posted a helpful article about fixing Wi-Fi pain points here. We have a few more suggestions and tips to better share your home network.

The first step is to assure that your router is centrally located in your home. Router antennas send Wi-Fi signals out in all directions. So, if yours is tucked away in a corner of your home your wireless coverage might be pointing outside. A central location will optimize your signal. Ideally the router should be off the floor and placed as high as possible. It’s also important to keep the router away from obstructions, such as TVs and other large electronics. The more obstacles near your router, the more interference with the signal.

Don’t forget to stay close to your Wi-Fi router when you’re using data-intensive applications. The closer the device you are using is to a Wi-Fi router, the better its connection will be. If you have several people on the internet in your household all at the same time watching online videos and such, consider using standard definition (versus high definition) to help things run smoothly. Go into video settings on your streaming platforms and lower the resolution as needed. Do you really need full HD 1080 resolution for the kids to watch Baby Shark? Look for “data saver” or “good” under the settings of your favorite services. Also consider lowering the video resolution on your webcam to 720p to ensure great video while reducing the risk of the kids competing with you for Wi-Fi bandwidth while binge-watching Star Wars movies.

Services such as Zoom, Google Hangouts and Webex allow for changing your video resolution under their settings tabs. Others may require a change by your systems administrator. It can help to turn off your video security cameras and nanny cams while at home or not in use too.

If you’re on a deadline for work or school and need to try and speed things up, try minimizing the use of concurrent devices and applications (e.g., gaming or watching streaming video) to reduce conflict. Backing up videos, pictures and files can take a while, depending on the size and other applications being used. Schedule and perform large file backups during overnight hours.

Don’t forget that having multiple tabs open on your browser can slow things down, especially if you’re streaming music or have a video running on different websites in the background. This can cause a decrease in your browsing speed, so we recommend closing tabs when they’re not in use. We’re all used to working wirelessly these days; a wired Ethernet connection will speed up data transfer from your computer to the Internet. So, go to your garage or closet where you store your miscellaneous electronic accessories and dig up your CAT 6 (standard twisted pair cable) cables to use a wired versus Wi-Fi connection for your PCs, gaming consoles and TVs if available.

By taking some of the steps outlined above, we can all help improve our Internet experience within the home network. We will get through this and whatever comes next!

  Better Home Networks: How EasyMesh™ Delivers Intelligent Wi-Fi

John Bahr
Principal Architect, Wireless Technologies

Sep 11, 2018

Today, many people view Wi-Fi as an essential component in their home. However, people routinely experience connectivity issues because networks aren't capable of broadcasting their Internet signal adequately and uniformly throughout their home or business. CableLabs is working with the Wi-Fi Alliance (WFA), and its new EasyMesh™ certification program, to solve this problem and provide extended, uniform coverage throughout your entire home.

Watch our video below to learn about the benefits of Wi-Fi EasyMesh™ and how the certification program will create better home networks by bringing network intelligence to multiple access point (multi-AP) deployments.

Wi-Fi Alliance members are now able to submit their products for testing. Interested in learning more? Read my blog "EasyMesh™ Brings Super Connectivity to Home Networks" and subscribe to our blog.

  AP Coordination in Home Networks

Jun 7, 2016

Multiple Access Points Can Improve Home Wi-Fi Coverage:  The Secret Sauce is AP Coordination

Before we address AP Co-ordination in Home Networks, it is important to note that average home sizes have been increasing at a steady pace in the past four decades as seen from the figure below.

Increasing Home Size

As consumers, we expect our home Wi-Fi network to be ubiquitous, providing reliable connection speeds wherever we are in the home.  A single AP may not be capable of providing whole home coverage, especially in larger sized homes. In a recent blog post, my colleague Vikas Sarawat described how a range of multi-access point architectures have emerged to solve this coverage gap.  These architectures solve the whole home coverage problems but there are other gaps that need to be addressed in order to have an overall positive Wi-Fi experience.

Single AP vs. Multiple AP Architecture

For example, most consumer grade access point solutions currently lack a centralized Wireless LAN controller (WLC).  In general, a WLC acts as a commander-in-chief which manages and controls all the APs that it serves and thereby leads to network optimization.

In the absence of a centralized WLC, multiple APs do not communicate with each other.   In fact, they can at times treat each other as rogue APs that are not even operating on the same network.

Hence, there needs to be some sort of a direct communication protocol between these multiple APs in-order to provide a good Wi-Fi experience to the consumers. Although AP co-ordination has been a topic of research in a controller-based architecture ecosystem (e.g., for enterprise and community Wi-Fi environments) for some years, historically, the residential consumer premise equipment vendors have not paid much attention to coordination since most homes only had a single AP.  To address this shortcoming, CableLabs is actively working on defining and standardizing the AP coordination protocols.

Our goal is to have a lightweight AP co-ordination solution that provides the following two benefits:

Optimal AP selection: When there are multiple APs available, many clients rely solely on signal strength to decide which AP to connect to, but it might not always be optimal concerning throughput for the client.

There are often conditions where a lower received signal strength indicator (RSSI) from the gateway AP may provide better throughput than a stronger RSSI from the repeater. The client cannot determine which is the best connection on its own – the infrastructure must inform it. Choosing the best point of attachment in each location is a decision that warrants information and intelligence on the client-side, the network-side, or possibly both.

Client Steering: APs also need to decide when and how to steer clients to the best AP based on network conditions (e.g., load, bands). This is especially important since many clients prefer to stay associated with one Wi-Fi network even though another Wi-Fi network with “better” connectivity is available. This is commonly referred to as the "sticky client" issue.

With AP co-ordination, the APs can exchange information on how best to get rid of the sticky client problem in a standard fashion. A partial solution has been defined in the IEEE 802.11k and 802.11v standard but not many APs or clients implement them yet.

While the IEEE 802.11k defines methods of retrieving information from clients in the form of neighbor requests and reports, the IEEE 802.11v standard provides the AP with the ability to configure client stations wirelessly in the form of the BSS Transition Management (BTM) feature.

To summarize, AP coordination is an important topic of research, particularly within the home networks where there is no WLC.  CableLabs is actively engaging with the vendor community to develop a standard way of implementing in-home AP coordination protocols which we plan on submitting to the standards bodies such as WFA and WBA in the near future.
