A disrupted Wi-Fi signal means many things, but there’s always a solution.
  • Placing your router in an open, central area allows the Wi-Fi signals to freely connect to devices. When you place your router in an enclosed space, the walls block those signals.
  • Not every device needs to be connected to your home internet at all times, so be sure to disconnect unused devices for better connection.
  • Upgrading your router and its software will show a noticeable improvement in how fast and reliable your internet connection can be.

Dealing with home internet that keeps disconnecting and disrupting your work, entertainment, and communication is frustrating. We’re here to help you alleviate this frustration by pointing out common reasons for disconnected Wi-Fi. We’ve also paired each reason with a practical solution so you can resolve connectivity problems and ensure a stable and reliable internet connection.

Your Network Is Congested

Connecting too many devices at once can cause your network to slow down or shutdown.

Network congestion can lead to frequent Wi-Fi disconnections due to the overwhelming volume of data traffic coming through the network. When multiple devices simultaneously access the internet or stream content, the available bandwidth gets divided among them. As a result, the Wi-Fi network becomes congested, causing the connections to drop intermittently.

Congestion can strain the router’s processing capacity, exacerbating the problem. This issue is particularly common in densely populated areas or households with numerous connected devices competing for bandwidth.

How to Fix Network Congestion

For a quick fix, disconnecting devices that aren’t in use can help clear congestion to make room for in-use devices. However, this won’t address continual problems if you’re living in a house with many connected devices. I know this because I used to disconnect my kids’ iPads whenever they weren’t using them and our internet still didn’t improve. Whether your household has multiple people who use smartphones, streaming devices, and laptops, or if it has several smart home devices connected to Wi-Fi at one time, a consistently congested network needs a long-term solution.

You can either upgrade your internet plan or invest in additional routers, such as a mesh Wi-Fi network. Our household went the latter route and it’s been a huge improvement (plus, everyone wins). Either solution will provide more bandwidth for devices to connect and reduce congestion.

Your Router’s Location Is Blocking Signal

Improper router placement can significantly contribute to Wi-Fi disconnections due to interference and poor signal coverage. When the router is placed in a location with obstacles such as walls, furniture, or electronic devices, the Wi-Fi signal strength weakens, leading to frequent dropouts. Placing the router too far away from the areas where Wi-Fi connectivity is needed can exacerbate the problem, as the signal may only effectively reach some corners of the home.

How to Find Optimal Router Placement

Position the router in a central location within the home to boost Wi-Fi signal coverage and minimize interference. Place the router at a higher elevation, such as on a shelf, to reduce obstructions. You may need to test different locations within your home to find the optimal spot. I’ve had to test this out in many rooms in my house until I was satisfied with leaving it in one corner of our living room on top of our bookshelf.

If Wi-Fi dead zones persist, implementing Wi-Fi range extenders or mesh networking systems can help extend coverage to hard-to-reach areas. These types of systems are especially advantageous for homes with multiple floors or with more intricate floor plans.

You Have an Unsecured Network

An unsecured Wi-Fi network can be a significant reason for frequent disconnections due to external factors exploiting the vulnerability. Without proper security measures such as encryption and authentication, unauthorized users can gain access to the network, causing congestion, bandwidth theft, or even malicious activities. Intruders accessing the network may inadvertently or intentionally interfere with network settings, leading to disruptions in connectivity for legitimate users.

How to Secure Your Home Network

Securing a network is crucial for avoiding Wi-Fi disruptions as well as protecting against unauthorized access and malicious activities. Enabling Wi-Fi encryption protocols such as WPA2 or WPA3 ensures that data transmitted over the network is encrypted, preventing unauthorized access. Configuring strong and unique passwords for both the Wi-Fi network and the router’s administrative interface helps prevent unauthorized users from gaining access. Regularly updating router firmware and enabling firewall settings can also protect against known vulnerabilities and external threats.

Your Internet Is Being Throttled

ISP throttling happens to the best of us, but that shouldn’t stop you from staying connected.

If your internet keeps going out, it could be due to throttling imposed by your internet service provider (ISP). Throttling occurs when ISPs intentionally reduce the speed or bandwidth of your internet connection, typically in response to exceeding data usage limits or during peak hours of network congestion. This can result in frequent disconnections as the connection struggles to maintain stability under reduced speeds. Throttling can impact activities that require consistent bandwidth, such as streaming videos or online gaming.

How to Prevent Throttling

Consider upgrading to a higher-tier internet plan with more generous data allowances or unlimited data to avoid triggering throttling thresholds. Also, using a virtual private network (VPN) can help mask your internet activity from your ISP, making it more difficult for them to detect and throttle specific types of traffic. Monitoring your data usage and being mindful of bandwidth-intensive activities during peak hours can help prevent triggering throttling measures.

Contact your ISP about their throttling policies and negotiate for more consistent speeds or alternative plans with fewer restrictions as these things are beneficial in maintaining a stable Wi-Fi connection.

Your Equipments Needs to Reboot

Over time, your router and modem can accumulate temporary glitches or memory leaks, leading to degraded performance and intermittent connectivity problems. Rebooting your equipment can help clear away common network issues. Prolonged periods of uptime without a reboot can cause the router and modem to become overwhelmed or overloaded, resulting in malfunctions that manifest as frequent disconnections. Software updates or configuration changes may require a reboot to apply properly, and neglecting to do so can lead to instability in the network connection.

How to Reboot Your Router and Modem

Rebooting clears the router or modem’s memory and resets its internal state, effectively eliminating any temporary glitches or software conflicts that may be causing connectivity problems.

If you need to reboot the router and modem, power off the devices. Wait for a few minutes to ensure all power is drained and then power them back on. Start with powering on the modem first and allowing it to establish a connection with your ISP. Then, power on the router, allow it to load up, and create a connection. Rebooting your router and modem is a regular maintenance practice you should complete monthly to prevent Wi-Fi disruptions.

Your Equipment Is Old

Outdated routers and modems can be a significant reason for Wi-Fi disconnections as they may lack the necessary features, performance capabilities, or security enhancements found in newer models. Technological advancements and updates in networking standards may render older devices incompatible with modern Wi-Fi networks, leading to connectivity issues such as dropped connections, slow speeds, or signal interference. Older hardware components may also degrade over time, resulting in decreased reliability and performance that further exacerbates Wi-Fi connectivity problems.

How to Upgrade Your Router and Modem

On average, routers and modems last for five years and will likely need to be upgraded if they’re older than that. In many cases, your router and modem were supplied to you by your ISP. If you’re concerned about the age, you can reach out to your ISP to have these devices replaced.

You can also purchase your own equipment to ensure you’re getting the most updated equipment. Before purchasing a new router or modem, research and consider factors such as Wi-Fi standards, dual-band support, and security features. Select a router or modem from reputable manufacturers known for reliable products and good customer support to ensure a better overall experience.
