Why does my new computer have slow internet connection?

First: Check your speed

Before doing anything to alleviate a potential internet speed problem, you’ll need to know two things:

  • How much speed you’re supposed to be getting from your ISP
  • How much speed you’re actually getting

Prior to running a speed test, we advise that you check your ISP service account to see what kind of speed you’re paying for. For example, I currently receive internet access through Comcast. For $89.95/month, I’m supposed to be getting up to 100 Mbps. Comcast doesn’t spell out exactly how much speed I’m getting anywhere on my account, however. It merely states the service package I’m using. I only know my exact speed because I recently changed the terms of my account, however, I could use the service package name to look that information up on their website as well.

You may need to do some legwork to research what your service package offers if your ISP doesn’t have the speed maximums and minimums listed on your account. A quick method may be to contact the company either by phone or live online chat to figure out what your bitrate is supposed to be.

Also, note the “up to” part. All ISPs will advertise a maximum or minimum potential speed you could get with what you pay. However, you will likely never actually achieve the advertised maximum speed, and your speed may fall below the listed minimum. Advertising a theoretical maximum or minimum speed is a common tactic ISPs use to attract customers. But failing to achieve those speeds is also just a consequence of having to share the bandwidth with your neighbors. At any given time, your actual speeds will vary as more or fewer people near you using the same ISP are also streaming Netflix videos or playing games online.

Running an internet speed test

After you’ve identified the speed you’re supposed to be getting, you should run a few internet speed tests.

Before running your speed tests, we recommend turning off any other data-intensive activities. That includes pausing downloads, turning off online games, and turning off streaming videos or music. The more devices you have running, the slower your available internet speed (something we’ll get into later), so you’ll want to get as accurate a measure of your speed as possible.

Ideally, you will want to run your speed test during the hours you would normally be using your internet. For weekdays, that’s typically in the morning or evening hours. On weekends, it could be anytime during the day.

However, it ultimately doesn’t matter when you run your speedtest. All that matters is that you run your before and after speed tests around the same time, and that you use the same speed testing website to run both tests. This will ensure you collect an accurate reading when determining whether the below methods work for you.

Here’s one example what my mid-day speed test results look like:

I used Internet Health Test for this report. Most people opt for for these tests, but is not the only internet speed testing option, nor is it the best one available. Some sites, like , only check internet speed through a sample download and upload to one server. However, other services, such as Internet Health Test, actually test the amount of congestion on your ISP’s network to determine speed.

We recommend testing your speed using a few different services. These tests typically take under 30 seconds.

Additionally, you’ll notice a lot of variation among speed test result shown below. Your bandwidth can fluctuate a lot during the day, as mine did while testing these methods. And as this guide was written over the course of several days, you’ll see a variety of speed results, all coming from the same network.

Here are additional speed results from other popular internet speed testing sites.

There are other speed testing websites out there, but these four should cover your needs and provide the most accurate analysis of your available upload and download bandwidth.

You may even want to simply test your speed the old-fashioned way: downloading a file and recording how long the file takes to download.

Across the different methods, you’ll see a lot of variation. This is why it’s important to try out a few services, as they can all give various readings. However, you may want to stick with one or two that appear to be the most consistent.

With that out of the way, here are a few speed boosting tips you might want to explore.

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.

Step 3: Blocking browser pop-ups

A pop-up is a small web browser window that appears on top of the website you are viewing. Pop-up windows often open as soon as you visit a website and are usually created by advertisers. Web browsers have features called pop-up blockers that can prevent pop-up windows from appearing. In most pop-up blocker programs you can choose the level of filtering you want, select which pop-ups you want displayed and build a blacklist of those you do not. See Blocking Pop-up Windows or Advertisements for more information.

Problems with browser

The Internet may also appear to be slow because of the Internet browser you are using to browse the Internet. To make sure you are not running into browser issues, try an alternative browser on your computer (e.g., Google Chrome or Mozilla Firefox). If multiple browsers all seem slow, then you may have an issue with your computer or the network. If an alternative browser works, then the problem is with your primary browser, and we recommend troubleshooting that browser or sticking with the alternative browser.

3.  Disable Windows Update

I’ll be honest with you, this method works like a charm.

“b-b-but wait jake, doesn’t this leave my computer more likely to be affected by bugs and viruses.”

Yeah I know what you’re saying because I asked the very question myself. 🙂

The thing is, you don’t really have to disable it altogether,  you can still manually ask it to send you notifications so that you can choose when you want to update your Windows 10.

Here’s how can adjust the Windows Update settings to your comfort. 🙂

Step 1:  Go to Start, look for your Control Panel

Step 2:  Head over to your Administrative Tools

Step 3:  Here’s where you can find and get to your Services. Once you’re in your Services window, scroll down to Windows Update and turn it off.

Step 4:  To turn it off, all you have to do is just right click on it, and then select Properties.

Step 5:  Now Disable it from inside your Properties, and Voila! You’ve just disabled your Windows Updates (Don’t worry 🙂  just follow these 5 simple steps and you can re-enable it back whenever you want to)

Note from Jake

Note from Jake

It is important that you keep up to date with your Windows updates whenever you can as each update brings new and better ‘stuff’ that you might like actually!

The thing you have to keep note is whenever you turn it back on again and when you open your Windows Update in your settings to check for the latest updates, you will find a message saying that the updates were not installed because computer was stopped.

It’s pretty much a piece of cake from here, just keep clicking on Retry so that all your available updates are installed and up to date. Chances are if you left it disabled for some time then it will take two or three times (or maybe more) to Check for Updates until your computer says it is up to date.

Step 1: Detecting and removing spyware and adware

If the computer becomes slow after connecting to the Internet, or your home page changes to a page you do not want, or unwanted desktop links display, or advertising windows pop up repeatedly, then the computer probably has spyware or adware installed. Spyware and adware can be very difficult to remove manually. For more information about spyware and how to remove spyware from the computer, go to Computer Might Be Infected by a Virus or Malware (Windows 10, 8).

Direct connection vs. Wi-Fi

Wireless (Wi-Fi) technology has improved since it was first introduced. However, it still cannot offer the same reliability as a direct connection. If the computer or wireless device has a poor connection, it decreases your Internet speed. If you’re using Wi-Fi, move closer to the wireless router to ensure it’s not a problem with the wireless signal. If you get a direct connection to the router, we’d also recommend using an Ethernet cable instead of using wireless when you can.

8.  Disabling Large Send Offload (LSO)

This is another one of the features that you might find on Windows 10 and again it is meant to improve your overall network performance of your system (it’s pretty similar to the Windows Auto-Tuning level feature that you just saw above), but it does come at a price.

Your LSO forces your background apps (which includes your Skype, Spotify, etc.) to use up a large amount of your internet whilst you’re doing something else on your computer.

I’ll show you how you can disable it (you can re-enable it anytime). 🙂

Step 1:  Go ahead and open Start and then right-click on your Computer

Step 2:  Next, select Properties

Step 3:  Now from your Control Panel, click on Dev

Step 3:  Now from your Control Panel, click on Device Manager 

Step 4:  Here you will be able to see all your devices listed, but for now you will only need to expand your Network Adapters.

Step 5:  Next, look for your Network Card and then double click on that.

Step 6:  You’re almost there! Now select the

Step 6:  You’re almost there! Now select the Advanced tab and then go ahead and select Large Send Offload V2 (IPv4).

All you have to do here is set the value to Disabled.

Step 7:  Do the exact same that you just did for L

Step 7:  Do the exact same that you just did for Large Send Offload V2 (IPv6) (that is if, it is available).

Step 8:  Click OK and you’re done!

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:

  • Go to Windows settings > from “Update and recovery” menu > click on “Windows Update”

 Then, click on “Choose how updates get installed”

  • Then, click on “Choose how updates get installed” option and set update preferences as per your preference, or simply turn off the On
