How to Boost Xfinity Wi-Fi Signal at Home or Office

Deciding to use the Xfinity Wi-Fi connection is one of the best decisions you can ever make. But can you boost the Xfinity Wi-Fi signal for whole-home coverage? The answer is YES and very simple when you follow this guide.

However, it may be the most disgusting connection when the signal becomes unreliable. There are several reasons why the connection can turn out to be the worst.

The good news is that no challenge lacks a solution. You can restore your connection and have the signal quality improve again. Getting a reliable solution may not be simple if you have no understanding of the cause of the poor signal. Today’s major task is to bring to light why your Xfinity Wi-Fi connection is poor and why you need to boost it.

Causes of poor Xfinity Wi-Fi signal

Location of the router

The reason why your router could be delivering an unreliable performance is because of its location. For instance, if the router is on the floor or behind obstacles, the performance will be unreliable. It may also be limited to perform such as in corners or close to other electronic devices.

If your house is large, you will also challenge choosing a strategic position for its placement. Things such as television, fridge, oven, and electric fields make the signal remain poor. A quick solution to such a challenge is choosing an optimal location for the router to serve.

Applications in use

The most common mistake that people make when they get routers is that they overload them. When there are several functions such as streaming, gaming, surfing, and downloading simultaneously, the signal will lower. These are all services that need a lot of internet bandwidth to function.

What happens when there are too many functions taking place simultaneously is that they share the available connection. Speeds and signal quality become inferior, making the connection unreliable. Even the devices that do not need a lot of internet bandwidth to function begin to deliver an unreliable performance.

Range coverage

The range covered by your router may be limited. Any device that is operating beyond the coverage will have an inadequate connection. When several devices operate beyond the range, they bring their effect even to those closest.

The router could also be very poor I covering a wide area. The distance between your device and the router could be okay but affected by an obstacle. You can have a router covering a wide range, but the signal has to cross two walls to reach your device. By the time you enjoy the connection, the signal is already very poor.

Connected devices

Each router comes with a specific number of devices it can serve. When you exceed the number, the signal quality and the general performance begin to lower. The worst part of this scenario is having many high-performing devices operating within the connection.

The performance will become unreliable as each device scrambles to get good internet. Possibilities of having latency increase, especially when you have to game or do various activities.

Firmware update

Your router could be delivering very poor performance because it has an old version of the firmware. Some routers will automatically update after some time. Different models behave differently as some wait for you to do the update.

The performance of an outdated model remains very poor all through the connection. Devices may show some full signal, but the quality remains unreliable. Even when you have only one device working, the performance remains very poor. Routers that have automatic updates tend to serve better.

Insecure connections

Your router’s safety matters a lot if it has to perform as expected. We have models that do not have advanced security features. Some users care less about making the performance of the router enhanced. The biggest threat is having your neighbors using your connection.

The router’s password could be very poor, making everyone within the connection easily guess it. The result is that your neighbors will connect very many devices making the connection experience latency. Signal strength and quality also begin to lower so long as the devices are connected.

Noise from neighbors

Could you have a router that gets affected when your neighbors are using their Wi-Fi? This could be the reason that your Wi-Fi connection is very poor. Too many signals from other devices, especially stronger ones, tend to make a weaker connection unreliable.

Unfortunately, you cannot tell neighbors to stop using their connection so that you use yours. You need to come up with a way to deal with such a challenge. Some routers cover an extended range and deliver signals that you can interfere less with them.

Performance technologies

What are the technologies that your router has that will make the performance more enhanced? Some of the most common ones are powerful external antennas and beamforming technology. Combining the beamforming technology and the MI-MO will make the performance more enhanced.

If your router does not have any of these, then your signal is in trouble. They help in band allocation hence making your moments more remarkable. Unfortunately, it’s not all routers that have these features. Your router could be one of those that lack these features, which is why it delivers inferior performance.

How to boost Xfinity Wi-Fi signal

Various methods are very effective in boosting the Xfinity Wi-Fi signal. We have chosen the ones that are most effective and will deliver the best performance. After assessing why your connection is not reliable, you may have a solution while looking at the problems. If not yet, the section below should leave you smiling.

Update the router’s firmware

This is the fundamental challenge that may be affecting your router. Before you look at any other solution, you need to ensure that you have updated the router firmware.

Updating the firmware is essential as it adheres to the current updates, including the Wi-Fi technology updates. It is therefore an easy way to boost Xfinity Wi-Fi signal.

An updated router will also update the connected and existing devices. The performance of the router and the devices will therefore remain outstanding.  If you want to make everything simple for updates, you can let your router perform a routine update. Such a protocol ensures that your router is ever in the best state.

Remove obstacles or change the position of the router

The poor signal could be a result of barriers or bad placement of the router. If your router is behind electronics such as television sets, computers, ovens, and even the fridge, you will need to remove it for a better position.

Some people love keeping fish dishes in the house; it also affects the signal because it fails to penetrate.

Never put the router on the floor or at the corner. The signal will not penetrate any room beyond the wall as it also reduces the angle of signal projection. 

An optimal location that will facilitate serving an extended range is the best option to boost the Xfinity Wi-Fi signal. It will ensure that the signal covers a broader place and at least some manage through the walls.

Invest in mesh Wi-Fi

If you have not tried having mesh Wi-Fi, you need to try it now. Mesh Wi-Fi is good because it covers the entire place that the range extends. Amazingly, it does not force itself through the walls. The connection identifies the device that is closest to it and serves it with the connection.

In simple terms, the mesh Wi-Fi moves like smoke. So long as there is an open place, it coves it all with a reliable connection. You will buy and add a mesh device to the connection every time you intend to improve.

Mesh connection is cost-effective and improves the efficiency of the connection. As long as you get an Xfinity compatible mesh system, you will be able to boost the Wi-Fi signal comfortably.

Use an Xfinity Wi-Fi extender

Using an Xfinity Wi-Fi extender is another method that will make your signal better all through your range. Various extenders come with different specifications to help in boosting the range. Wi-Fi extenders are great devices because they make the signal coverage great and also improve the signal quality.

Having the best extender for Xfinity is a good thing as it will work with the service and make the connection reliable. Some people may also wonder about how extenders join the connection. Below is a simple guide that will help you to connect an Xfinity Wi-Fi extender conveniently.

Prioritize devices and service

Another way to boost the Xfinity Wi-Fi connection is by prioritizing the devices so that they deliver reliable performance. You can do this by logging in to the user interface. On the settings options, you pick the option that allows you to view your devices. You can choose to have those that you need to enjoy the connection enjoying the service.

The option also allows you to block intruders from using the connection. You can also prioritize specific services such as streaming or gaming so that you get a good connection when they are working.

Enhance the security measures of the router

When the security of the router is enhanced, the signal also improves.  You can do so by changing the password of the router. All the devices will then be disconnected as you get the room to make fresh connections.

Some people also prefer to set the router to provide notifications for any device that wants to join the connection. Such an option will help to make the security much better.

When you change the password, the chances of having your neighbors getting into the connection lower to a great degree.

Get high performance antennas antennas

The beamforming technology is widely known for enhancing the range coverage. If your router does not have beamforming technology, you can choose to have it.

When you combine the technology with powerful antennas, you will have an opportunity to boost the Xfinity Wi-Fi signal to reach the devices located at the farthest end of the connection.

Adjustable antennas are suitable because they help you direct them towards a specific direction hence increasing the signal coverage. If your devices are located at a particular point, you should focus them on that side and see the outcome. Of course, you will not be disappointed.

Use Ethernet cables for wired devices

When the high streaming devices such as gaming machines and computers use wireless connections, the signal becomes poor for the other devices. You should therefore use cables for some devices. The outcome of using cables is that the signal quality gets perfectly delivered to the devices,

The wireless service remains for the devices that need it. You will therefore have a powerful signal for the devices as they sliver high speeds too.

Change the router

Sometimes the router you are using is the problem. Changing it will create a permanent solution. However, there are several factors you need to look at when changing the router closely. You need a model that will cover an extended range and also supply high-quality signals.

Some of the technologies that can get you an Xfinity boost in your modem router or router include Beamforming, Wi-Fi 6, high-performance antennas, QoS, and a good processor among others. You should get a dual-band or tri-band router for the best performance.

Focusing on quality, the number of devices to accommodate, internet speeds, and performance technologies will enable you to compare routers and get the best. A good router will ensure that the signal even manages through obstacles such as walls and long distances. One that will automatically update will make the ideal choice.

Change the routers channel and band

Each wireless router operates within a specific channel. The settings are available on the wireless settings and will make your work easier. Changing the router channel will enhance the performance because you will experience more comprehensive coverage and prioritization.

If there is MU-MIMO and beamforming technologies, your router will then serve specific devices without any struggle. You can also choose to work on the bandwidth and the frequency as they will also enhance the performance.

The 2.4GHz band is known for having a longer range as compared to the 5GHz band. But is is also subject to interference from radio devices such as microwaves, walkie-talkies, baby monitors, and Bluetooth devices. Therefore, if you are having a poor coverage, change the band to 2.4GHz band for the slower but wider coverage.

Limit the number of devices

The number of devices in your connection also matters a lot. If few devices are operating within the connection, the signal gets maintained. Ensuring that specific devices operate in the connection will make your connection works convenient and straightforward.

You can also choose a combination of devices that will be working together. Such a plan will ensure that there is no time you will experience poor connection because of congestion.

What are the complications of a bad connection?

The internet is great. It allows people around the world to interact with others in their own time and location, creating a global community of people who share common interests and views. However, there are some problems that can occur with a poor internet connection: it’s slower than usual
