In addition to these questions, there are a few important factors you must consider for buying the best WiFi Extender for Comcast.

Factors to Consider for Buying the Best WiFi Extender for Comcast

  1. Features and Specifications

Not every Wi-Fi extender is the same. There are a variety of models available, which differ in features, size, specifications, weight, and more other aspects. You must check all specifications of models shortlisted by you to make an ideal pick that perfectly caters to all your requirements. The most important specification is that it must be compatible with maximum number of devices in your home or office.

  1. Security

This is one of the most important considerations. Your Wi-Fi range extender must ensure absolute security of your network.

  1. Brand Value

Though Wi-Fi extenders from top-notch brands may cost you a little more, but they are definitely worth the price. It is because devices from low-quality brands may not be engineered using best-quality components. Also, they do not come with any warranty and are not backed by customer support. All this can increase your problems and eventually result in a headache.

  1. Customer Ratings and Reviews

Always make sure you check online reviews for the Wi-Fi extender before you finally hit the order button. It is because there are various networking equipments that are popular for reliability, but they may not be able to perform flawlessly within your setup. Moreover, buying two products from the same manufacturer may not offer optimal performance. Hence, check online ratings for a product before the final selection.

  1. Durability and Quality

Just like most of the other devices, the Wi-Fi extender you purchase must impart high durability. It must be designed using high-quality components as only then it can serve you for a longer time period.

  1. Product Value

A product is valued high when it is able to meet the requirements of most of its customers and serves them in the best possible manner. For this reason, such devices are always high in demand. Hence, always take into account the product value of a device so that you never experience any problem or suffer from any issues while using it.

  1. Kind of Set Up

For tech-savvy individuals or tech professionals’ one important requirement is to want an extender that blends well with the internal settings through the web browser. The simplest set up is when both the extender and Wi-Fi box holds WPS or Wi-Fi Protected Setup.

Having WPS button on both the extender and Wi-Fi box ensures that it allows the system to interact with each other. This will ensure you have a simple setup without fiddling around with your existing settings.

  1. Double-Band Frequency

A few Wi-Fi boxes run on 2.4GHz, some on 5GHz and others on both bands. You must pick an extender that perfectly matches the frequency of your Comcast device. It must boost a 2.4GHz signal, but enhancing the short-range 5GHz signal can be stronger. You must pick a double-band extender that serves both the frequencies.

There are also tri-band extenders available that hold a dedicated band for communication between extender and router along with 2.4GHz and 5GHz for the devices. It boosts the process of communication and precisely serves the extended part of the network.

  1. Seamless Roaming

To ensure that your Wi-Fi extender works seamlessly within the office or home, you must pick an extender that can be set to the same network as served by your main Wi-Fi network. It is great if it can automatically switch between the extenders and Wi-Fi router to get the best signal. The extender must work seamlessly and in a way that it is a component of the entire home Wi-Fi mesh system.

  1. MU-MIMO Extender

The Multi-user, Multiple-input, Multiple-output is a feature supported by most of the advanced extenders available these days. With the help of this feature, it is possible to connect multiple devices in your house or office with the router at one point of a time. This reduces the wait time for all such devices, which makes the Wi-Fi network perform efficiently and faster.

  1. Signal Strength Indicator

It is essential to place your Wi-Fi extender at an appropriate place to gain the best signal. Placing the Wi-Fi box too close will not offer the best coverage. At the same time, placing it too far will weaken the signal. Hence, you must look for an Extender that comes with an indicator for signal strength. This way, you can easily find the correct position for your device.

How Does a Wi-Fi Extender Work?

Using a Wi-Fi extender does not mean you have to replace the existing router, because it works simultaneously with the router making the signal stronger.

Wi-Fi extenders function like stereo amplifiers that are used within Hi-Fi driving systems. They require an electric connection to boost the strength of original Wi-Fi signal, transferring the amplified signal range in the air.

For this, Wi-Fi extenders are incorporated with two Wi-Fi antennas. The first one is used for capturing signals, while the second one is used for transmission of signals.

Most commonly, a Wi-Fi extender is referred to as a repeater or a booster because its main purpose is to boost the strength of your overall Wi-Fi network.

To start using it, you have to plug in the extender into a standard electrical outlet. It can be then set up within your network using the WPS button or a smartphone app, based on the model you select. WPS is a standard for network security that enables Wi-Fi devices to communicate without allowing outsiders or entering long passphrases.

Picking the best Wi-Fi extender lets you enjoy a robust system encryption protocol, which you get with the main Wi-Fi router. Hence, it imparts more security to your privacy. But this can lead to some loss of speed.

Also, Wi-Fi extenders can rebroadcast Wi-Fi signals at only negligible speed loss. To ensure you get the performance with your extender, you must place it at an optimal position. For this, it is best to purchase Wi-Fi extender displaying signal strength or hire professional assistance.
