Internet Slow On One Computer But Fast On Another (Causes, Fixes)

Reset your network adapter

It’s worth doing this just to see if it’s the adapter at fault. You can disable and restart it by finding the adapter in the Control Panel (look under Network and Internet > Network and Sharing Centre > Change adapter settings).

Right-click the connection that’s currently being used and choose Disable. Leave it a few seconds, then double-click it to enable it again.

A restart of your PC can also have the same effect

A restart of your PC can also have the same effect. Just remember in Windows 10 you need to choose Restart, not Shut Down because the latter saves the system state and doesn’t really close everything down.

If that doesn’t work, try running the following commands. Launch CMD.exe or PowerShell depending on your version of Windows and  type (or copy and paste if you have Windows 10) these three, pressing Enter after each one.

Beware of Worms and Other Malware

An internet worm is a malicious software program that spreads from device to device through computer networks. If any of your computers become infected by an internet worm or other malware, they may spontaneously generate network traffic without your knowledge and cause your internet connection to appear slow.

How Do I Fix Windows 10 Slow Internet Speed Problem?

1: Monitoring Windows Updates

The automatic updates are by default enabled in Windows 10 and as a result, the update function stays active in the background and eats up huge masses of network bandwidth. As it checks and downloads entire updates.

So, to boost the Internet speed it is recommended to temporarily disable the Automatic system feature. This feature turns the system into a file-sharing server to reduce the central Window’s server but this makes the network services constantly engaged in background activities.

Follow the steps to disable it:

Computer woes: spyware, viruses, and other programs

The health of your computer can affect your Internet connection. Spyware and viruses can definitely cause problems, but your Internet connection speed can also be affected by add-on programs, the amount of memory the computer has, hard disk space and condition, and the programs that are running.

Two of the most frequent causes of poor Internet performance are spyware and viruses. Spyware can slow your system by interfering with your browser and monopolizing your Internet connection. Spyware monitors your Internet use and keystrokes, which adds delays. The problem is compounded when there are multiple spyware programs running at the same time. If the problem is severe enough, you can lose connectivity altogether. To get your Internet performance back, you should regularly run an antispyware program to clean out any spyware infestation.

Computer viruses can also cause poor Internet performance. When a virus infects a computer, it installs computer code which will attempt to propagate itself, usually by sending copies of itself through e‑mail. Some viruses can multiply at the rate of hundreds of e‑mail messages per minute, which leaves little computing power and Internet connection bandwidth for anything else. Viruses often don’t give any obvious indication that they’re running, so it’s best to run your antivirus software at all times.

Browser add-ons also cause performance problems. Browser add-ons are programs, such as multimedia add-ons, search bars, or other programs that usually appear on your browser’s toolbar. Many browser add-ons can add to a rich browsing experience, offering multimedia or specialized document viewing. However, some add-ons can slow your Internet connection. If you suspect that add-ons are causing slow performance, try starting Internet Explorer in Add-ons disabled mode. Add-ons are disabled only for the session, but if you find your performance improves, you can use the Add-on Manager to turn them off permanently. To access the Add-on Manager from Internet Explorer, click the Tools button, and then click Manage Add-ons.

Like all computer programs, Internet Explorer requires a certain amount of computing power, memory, and disk space to run efficiently. Every webpage you view is first downloaded to memory and then saved to temporary disk files. Running another program that’s using lots of memory and computing power can compete with Internet Explorer and cause delays. If you find your Internet connection running slowly and you have other programs running, try closing them. If you want to run several programs, consider increasing the memory you have on your computer. Low disk space can also cause performance problems. You can increase your disk space by deleting Internet Explorer’s temporary files.

Occasionally, settings get changed in Internet Explorer that could possibly affect how Internet Explorer works. You can reset Internet Explorer to its default settings. Resetting Internet Explorer isn’t reversible, so you should read the list of settings that are affected before resetting.

Call Your Internet Service Provider

Internet speed ultimately depends on the service provider. Your ISP may change its network configuration or suffer technical difficulties that inadvertently cause your internet connection to run slowly. ISPs may also install filters or controls on the network that lower your network performance.

Don't hesitate to contact your service provider if you suspect it is responsible for your slow internet connection.

Different types of internet connections offer different trade-offs. If you have a DSL connection and experience slowdowns during peak evening-and-weekend periods, it may be that many connected households are using the same access point in your neighborhood.
