What is ping?
Ping is the response time for how long it will take for device to get information from a particular server anywhere on the web.
Internet signal acts like a courier. Whenever you are gaming online, streaming shows or surfing the web for any information you are sending the courier to fetch data from the servers located at different locations out there in the world.
Think of your internet speed as depicting the amount of information a courier can carry in one trip, measured commonly in megabits every second (Mbps). The ping reveals to you how long it is taking to complete a trip, measured in milliseconds (ms).
If your connection is laggy it is referred to as high ping, the time to make a complete trip is high. Similarly, the lower the ping the more stable is your connection.
For gaming, high ping is destructive, its a measure of how long it takes for your computer to match the game state that the server is in. Getting location or environment data slowly means you’re more out of sync with the server state, this can mean you miss your shots or you can’t react to certain moves in fighting games.
How can you lower your ping?
First of all, take a speed test and check the latency. If the ping is high follow these steps to lower the ping:
Use Ethernet instead of WiFi
Changing to Ethernet is a simple move to bring down your ping. WiFi is known to increase latency, packet loss, and jitter because of interference of a wireless signal, any other wireless devices or even walls can hinder connectivity. Connecting to a device directly with ethernet is the most ideal approach to guarantee you have the least amount of ping and a substantially steadier connection.
Close background Applications
The most ideal approach to guarantee a quality encounter is to turn off other programs and let your game dominate. Some background programs use a lot of bandwidth, resulting in increased latency (high ping). Common offenders of bandwidth are Steam, Twitch, Netflix and Torrent downloaders, etc. Check if any software is using the internet to download software updates.
To take a look at processes in Windows 10, right-click the task bar and open Task Manager, from there, take a look at the processes tab and sort by network to see what’s using the most internet.
Choose the nearest server
The most straightforward approach to lower the ping is to choose the servers that are closest to your area. Any server which is nearest to your area will permit better correspondence between server and your PC, and would in this manner extraordinarily help the ping time. Games like CS:GO provides the liberty for you to select between various servers depending upon your location. Selecting the correct server will significantly lower your ping and enhances the game experience.
Reduce the number of connected devices to the router
Each device connected to a network uses some bandwidth and puts a strain on the router to control the traffic. Too many devices can affect the latency and stability of the network as the router is busy in dealing with a lot of traffic for each device. Lowering the number of devices will result in better connectivity.
Setup quality of service on your router
Some routers have a quality of service feature, quality of service allows you to set priority of ping and throughput by device or traffic type. You could implement QoS that prioritizes your machine or gaming type traffic over other traffic. In theory, QoS should reduce ping while not being too detrimental for other traffic that doesn’t require good ping, Netflix and Youtube don’t need a responsive ping to stream video for example.
This is a good resource for further reading into quality of service. Do note that not all routers support QoS.
Restart the router and modem
If your router has been on for a long time, it may not function properly. Turn off your router for at least 10 seconds and then turn back on. It cleans the cache of the router and refreshes your connection. Doing so can result in lowered ping rate. Do the same for your cable or DSL modem to refresh your connection.
Contact your ISP (Internet Service Provider)
Sometimes bad ping has nothing to do with your setup. Contact your Internet Service Provider and make them aware of the ping issue you are facing. They’ll either provide a fix from their end or guide you through the process for client-side fix.
Game specific fixes
CounterStrike: Global Offensive
Ping is crazy important in a one shot kill game like CS:GO, a couple of milliseconds too slow could mean the difference between who shoots first.
CS: GO supports in-game console. Hit the tilde (~) key to open up the console menu.
