Whenever possible, opt for a wired ethernet connection. While Wi-Fi is convenient, it can introduce latency and instability on your network, especially if you are far away from your router. Also, if there are multiple Wi-Fi networks in your area, they can interfere with your own network potentially causing packet loss. Additionally, various Bluetooth devices can sometimes share the same operating frequency as your wireless network. This can cause major problems if both your Bluetooth device and your Wi-Fi network card are located near each other. Switching to ethernet will eliminate these issues while providing a stable link directly to your network which can drastically improve your network stability.
While playing video games, you may experience lag spikes or dropped packets. To help find the issue, run this test on a second monitor or in the background while playing. If you notice a correlation between lag spikes on the monitoring tool and when you experience lag in the game, then the culprit is likely your own network. If not, then the issue is likely with the game’s server. You can also enable sound notifications when a certain latency threshold is hit. Enabling this feature will cause a soft bell sound to play every time there is a ping over the set amount. This means you can focus on the game and not stare at the ping monitoring tool.
This tool has the ability to run for an unlimited amount of time. That means you should be using this tool whenever you think there is a chance you will experience issues. The more often you are monitoring your network the higher the chance of you noticing a pattern of when you experience instability. The more information you gather the quicker you can determine the root cause. Also, try running the stability test while on both your home and wireless cell networks. If using a laptop or desktop, set up a mobile hotspot on your phone and connect to that. You may also try switching between any of the available servers around the world and see if you notice similar results.
Delving into your router's settings can significantly improve your network stability. Start by accessing your router's admin panel through a web browser, usually by entering its IP address. Once there, ensure you're using the latest firmware, as updates often include performance improvements and security patches. Next, experiment with changing your Wi-Fi channel. In crowded areas, many networks might be using the same channel, causing interference. Use a Wi-Fi analyzer app to find less congested channels. For dual-band routers, try separating your devices between the 2.4GHz and 5GHz bands. The 2.4GHz band offers better range but is more prone to interference, while the 5GHz band provides faster speeds over shorter distances. Consider enabling Quality of Service (QoS) settings if available. This feature allows you to prioritize certain types of traffic or specific devices, ensuring that critical applications like video calls or online gaming get preference. Finally, if you're not using certain features like WPS (Wi-Fi Protected Setup) or UPnP (Universal Plug and Play), consider disabling them as they can sometimes be exploited by attackers and may impact performance.
If you determine the issue to be on your end, it could be an issue with your modem or your Internet service provider. Always try resetting your router and or modem before anything else. In some cases, you may have access to the ONT box which sits between your modem and the outside network. Lookup a guide on how to reset your specific model from the ISP if you can access it. In conjunction with the previous tips, try running the stability test on various hardware. If you have an extra router or modem available to you, swap out one component at a time until you find the culprit. Even ethernet cables can be faulty, so swap out a cable, run the test again and then repeat. If all else fails, most ISPs provide online reset tools to which provide similar functionally to physically resetting your connection.
Network segmentation is a powerful technique that can improve both the security and stability of your network. This process involves dividing your network into smaller, separate subnetworks. Start by creating a guest network for visitors, which keeps their traffic separate from your main network and prevents potential security risks. If you have smart home devices, consider placing them on their own VLAN (Virtual Local Area Network). This not only isolates potentially vulnerable IoT devices from your main network but also prevents their often chatty nature from clogging up your primary network traffic. For those working from home, create a separate network segment for work-related devices and traffic. This can help maintain a stable connection for important work tasks and video calls, unaffected by other household internet usage. Advanced users might even consider implementing VLANs for different types of traffic or device categories. While setting up network segmentation might require some technical know-how, many modern routers offer easy-to-use features for basic segmentation. By properly segmenting your network, you can significantly enhance both its stability and security.
Optimizing your Domain Name System (DNS) settings and implementing effective caching strategies can lead to noticeable improvements in your network's performance and stability. Start by changing your DNS server from your ISP's default to a faster, more reliable option like Google's Public DNS (8.8.8.8 and 8.8.4.4) or Cloudflare's DNS (1.1.1.1). These services often provide faster response times and can improve your browsing speed. Next, consider setting up a local DNS cache server on your network. This can dramatically reduce DNS lookup times for frequently visited websites. For more advanced users, implementing a Pi-hole on your network not only provides network-wide ad blocking but also acts as a DNS cache, potentially improving overall network performance. On the client side, regularly clear your device's DNS cache to ensure you're not holding onto outdated DNS information. For Windows users, this can be done by running the command "ipconfig /flushdns" in the Command Prompt. Mac users can use the Terminal command "sudo killall -HUP mDNSResponder". Additionally, consider adjusting the Time-to-Live (TTL) settings in your router if available. A longer TTL for DNS entries can reduce the frequency of DNS lookups, potentially improving performance, especially for frequently visited sites. By optimizing your DNS settings and implementing effective caching strategies, you can reduce latency and improve the overall responsiveness of your network.
