Why Do Wireless Networks Have Ping Spikes?

Wireless networks can experience ping spikes due to various factors such as signal interference, network congestion, distance from the router, or hardware issues. These spikes cause delays and fluctuations in ping times, impacting online gaming, video streaming, and overall network performance. Let’s learn about them in detail.

Wireless Interference

Other devices you use in your home that produce microwaves will create interference between the Wi-Fi router and your device. Microwave ovens, cordless phones, and Bluetooth devices operate on the same 2.4ghz and 5ghz frequency bands as Wi-Fi.

Also, neighboring Wi-Fi networks can cause congestion, especially in apartment buildings.

Network Congestion

Too many devices using the same network simultaneously can cause lag. Streaming, gaming, or large file downloads consume high bandwidth and increase latency.

Weak or Unstable Signal

Distance from the router or obstacles like walls and furniture can weaken the signal. A weak signal causes packet loss, requiring retransmissions that lead to ping spikes.

Dynamic Frequency Selection

Wifi routers often change channels on 5ghz mode to avoid radar and microwave signals, which can cause momentary disruptions.

Background Network Activity

Some background tasks in your system, like automatic updates, cloud backups, and syncing services, can consume high bandwidth and impact your network latency.

Quality of Service (QoS) Settings

If you have a router that supports QoS settings and it’s not configured properly, critical data packets may be delayed during gaming and streaming.

Router or Modem Issues

Old malfunctioned hardware or outdated firmware can cause inconsistent performance and high ping spikes in your network.     

ISP Routing Throttling

Your Internet Service Provider (ISP) may have inefficient routing or bandwidth, which can cause delays. Some ISPs intentionally throttles specific types of traffic (e.g., gaming or streaming), leading to ping spikes.     

7 Ways to Get Rid of Ping Spikes on Wireless Network

Ping spikes occur when there’s a sudden increase in latency or delay between your device and the server you are connected to. Here are some effective ways to reduce or eliminate ping spikes on your wireless network.     

1. Use a good VPN

Usually, a VPN connects you to a private network server, and all your internet traffic passes through that server. Sometimes, your ISP can impose bandwidth throttling or geo-restrictions on your network. Now the question is, does VPN stop ping spikes? 

Yes! You can optimize gaming traffic routing using a VPN. It routes your data through dedicated servers optimized for gaming, reducing the number of hops and congestion. This can result in lower latency and fewer ping spikes.

Also, some VPNs, like the Symlex VPN have dedicated gaming servers to ensure high-speed gaming with no lag or ping spikes on critical moments.

Connecting to servers that are physically close to your location is recommended to reduce latency.

If you get less ping from the server, you’ll have a more responsive gaming experience. So, choosing a good VPN does improve your gaming.  In the meantime, make sure you pick the best vpn protocol for gaming.

2. Test Your Internet Speed

To make sure your internet connection is stable and performing well, run a ping test through CMD (Command Prompt) on your Windows PC. You can also run the ping or internet speed test on third-party websites like fast.com or speedtest by ookla.

A ping test is used to determine if a player’s connection is good enough to play the game without any lag. 

Ping rates can also be used to troubleshoot internet connections and improve connectivity, speed, and reaction time. Performing a ping network test/ping spike test varies depending on your operating system. Follow these easy steps for each OS:

Windows

• Type “cmd” in your windows search option to open the Command Prompt.
• Once the Command Prompt is open, type “ping” followed by a space.
• Enter the IP address you want to ping (e.g., 192.XXX.X.X). (You can get your gateway IP by using the command “ipconfig”)
• Review the displayed ping results. The following is an example of a normal ping response.

If the network is unreachable, it will look like the picture below.

Macs

1. Open Network Utility.

2. Input the hostname or IP address you want to ping.

Linux

1. Open Terminal.

2. Use the “traceroute” command followed by the IP address or URL you want to trace.

3. Hit Enter and review the results.

By following these simple steps, you can easily perform a ping network test on your respective operating system. 

3. Close Background Programs

Closing background programs is one of the ways to reduce ping spikes while gaming. When background programs and applications run on your device, they can consume bandwidth and cause lag spikes. 

To close background programs, you can use the Task Manager on your computer. Here are the steps to close background programs using Task Manager:

• Press Ctrl + Shift + Esc to open the Task Manager.
• Click on the “Processes” tab.
• Click on the “Memory” column to sort the processes based on their memory usage.
