How Do Wi-Fi Routers Work?

Wi-Fi routers are essential networking devices

Wi-Fi routers are essential networking devices that allow multiple devices to connect to the internet wirelessly. The router works by receiving data from the internet service provider (ISP) via a modem and then distributing it to connected devices through a wired or wireless network.

The router connects to the modem via an Ethernet cable, which is plugged into the modem’s WAN (wide area network) port. The router then broadcasts wireless signals to devices within range, allowing them to connect to the network using Wi-Fi. The router also has Ethernet ports that can be used to connect devices directly to the network using a wired connection.

The router assigns IP addresses to each connected device, which enables the communication between devices on the network and the internet. The router uses the Network Address Translation (NAT) protocol to assign unique IP addresses to each device and ensure that data is sent to the correct device on the network.

The router also provides security features to protect the network from unauthorized access, such as encryption protocols like WPA2 (Wi-Fi Protected Access II) and firewall protection. These security measures help prevent unauthorized access to the network and protect sensitive data from being intercepted.

Multiple Devices Reduce Wifi Performance

Router For Multiple Devices


The speed of the wifi slows down since it’s being used for various online activities via multiple devices. Although it’s quite usual, you shouldn’t neglect it.

Most homes are packed with IP cameras, smart voice assistants, IoT gadgets, automated devices, and mini robot gadgets that use the wifi.

Due to this increased usage of things that consumes huge wifi, it slows down the wifi performance.

In general, the home routers aren’t designed to handle multiple devices at one go that require huge capacity. Once the home routers cross a certain limit(most probably 30), you experience buffering, connection dropouts, increased load time, and several other poor connection issues.

Considering all these things, here comes the question – how to cope up with low-performance wifi?

Solution: Initially, know the age of your router. If it’s too old and outdated, it’s time to replace it with the latest router. Also, while choosing the wifi router, make sure you choose the ultimate scalable wifi router that ensures high-end wifi performance that support multiple devices.

You can also install a second network booting service or routers that offer fast wifi services. Did you know installing a second router is the best and simplest solution to enjoy fast wifi services?

That’s why most people install a couple of network boosting devices and enjoy exclusive wifi services without any interruptions.

For more precise information about the wifi performance and internet connections, it’s highly recommended to contact ISP(aka Internet Service Provider). Internet Service Providers advise you everything about the requirements to enhance internet connectivity for multiple devices.

7 Things That Are Affecting Your Wifi Performance

Till now, you’ve understood about multiple devices affecting your wifi and how to cope up with it. Now, let’s understand the factors affecting wifi performance other than multiple devices.

There are several other reasons contributing to the slowdown of wifi, such as unknown users using the wifi, less bandwidth, congested wifi channels, frequent interference in the network, and many more. So, let’s discuss various factors contributing to poor wifi performance.

Multiple Users

Usually, when multiple devices are used in the home, the internet speed is equally shared with everyone.

As a result, you experience delayed load time or buffering. In addition, there are chances that your wifi might be used by your neighbors or unknown people near your home which decrease wifi performance.

Since multiple people are using the internet, it disrupts the wifi connection.

Less Bandwidth

Upgrade to a larger bandwidth that handles multiple devices at one go without any interruptions. Usually, the lesser bandwidth leads to slow connectivity.


The interferences or disturbances in the network are one of the primary reasons for the slowdown of wifi. Mostly, the radio frequency of household devices interrupts the wifi and hence leads to multiple connectivity issues.

Congested Wifi Channels

Wifi congestion is one of the most common issues for people living in apartments or urban localities. In general, over 90% of homes use cheap home routers in urban areas within the available frequency range.

As a result, you might end up with lower bandwidth and constantly experience poor wifi performance.

So, try switching to the other channel number to enjoy the best internet services. Ethernet is the best alternative to wifi. However, you can use wifi for smaller devices such as printers and mobile phones.

At the same time, start using Ethernet for larger IoT devices, home automation, and other devices.

Slow Down of ISP’S DNS Server

DNS servers are the primary factors to consider for fast internet connection. Usually, this DNS server will be offered by Internet Service Providers.

If they have provided you with slow DNS servers, make sure you change it to a faster DNS server.

Although the upgrade of the DNS server might cost a few bucks, it certainly boosts your wifi irrespective of the number of users.

How To Speed Up Your Wi-Fi

If you’re experiencing slow Wi-Fi speeds, there are a few things you can do to try and improve it. Here are some tips:

  • Check your internet speed: Before you start tweaking your Wi-Fi settings, it’s important to make sure you’re getting the speed you’re paying for from your internet service provider. You can check your internet speed using websites like or
  • Restart your router: Sometimes, simply restarting your router can help improve your Wi-Fi speed. Unplug your router, wait for 30 seconds, and plug it back in.
  • Change your router’s location: The location of your router can affect its Wi-Fi signal. Try moving it to a more central location in your home, away from walls or large appliances.
  • Update your router’s firmware: Router manufacturers release firmware updates that can help improve Wi-Fi performance. Check your router’s manual to see how to update its firmware.
  • Change your Wi-Fi channel: Your router broadcasts its Wi-Fi signal on a specific channel. If your neighbors are also using the same channel, it can cause interference and slow down your Wi-Fi. You can change the channel in your router’s settings.
  • Use a Wi-Fi extender: If you have a large home or multiple floors, you may need a Wi-Fi extender to boost your Wi-Fi signal. A Wi-Fi extender picks up your router’s signal and re-broadcasts it, extending your Wi-Fi coverage.
  • Upgrade your router: If your router is several years old, it may not be capable of providing fast Wi-Fi speeds. Consider upgrading to a newer router with faster Wi-Fi technology.


The usage of multiple devices certainly decreases wifi performance and leaves you with either delayed load time or buffering.

A few other things affecting wifi speed are slow ISP’s DNS server, congested wifi channels, multiple users, and many more. However, the simplest way to prevent a slow down of wifi is to either change the router or install a new router.

For more precise details and personalized suggestions, you can even contact Internet Service Providers in your locality.

Frequently Asked Question

add multiple devices to wifi

How many devices can I connect to wifi?

In most cases, you can connect 250 devices for a single router. However, this isn’t the precise device count that you can connect to your wifi. This number varies for various routers with district features and functionalities.

Does the bandwidth reduce if I add multiple devices to wifi?

Yes, adding multiple devices to your Wi-Fi network can reduce the available bandwidth. Each device connected to the network uses a portion of the available bandwidth, and the more devices connected, the more the available bandwidth is divided. This can result in slower internet speeds for all devices on the network.

However, modern Wi-Fi routers are designed to handle multiple devices and allocate bandwidth fairly, so the impact on speed may not be noticeable unless you have a large number of devices connected at the same time.

To optimize your network and avoid bandwidth issues, it’s recommended to limit the number of active devices, disconnect devices when not in use, and consider upgrading your router if you have a large number of devices that need to be connected simultaneously.

Do old network cables affect the wifi speed?

Old network cables may affect Wi-Fi speed if they are not capable of transmitting data at the speeds supported by the Wi-Fi network. For example, older Category 5 (Cat 5) or Category 5e (Cat 5e) cables may not support the higher speeds of Wi-Fi 6 (802.11ax) networks. In such cases, upgrading to newer Category 6 (Cat 6) or Category 6a (Cat 6a) cables may help improve Wi-Fi performance.

However, it’s important to note that network cables are typically used to connect devices to the router, and not directly to the Wi-Fi network. The speed of the Wi-Fi network depends on various factors such as the router’s capabilities, signal strength, interference, and distance from the router. Upgrading network cables may help improve speeds for devices connected directly to the router, but it may not necessarily improve Wi-Fi performance.
