Windows 7 — Cannot connect to the internet

Do you have McAfee? It was updated at about the same time and it seems to be the cause of this problem.

See this «critical» McAfee notice —

You should do the McAfee fix, if applicable.

I had McAfee but the connection started working again of its own accord so I thought I was clear of problems. However, when I checked it said it had been doing routine checks for updates but failed when I told it to do one manually. So staying with McAfee without following their fix procedure would have put my PC at risk by not being updated and, as further McAfee announcements have since explained, the application was not referring to its threats database correctly. Actually, I removed it then installed Microsoft Security Essentials instead & my IE response is quicker than I have known it [even though I had had the McAfee add-ons disabled for ages].

I’ve had to run the McAfee MCPR removal a few times before and it caused a licence problem if the PC was not connected to the internet during the removal. The McAfee support chat had to reset their records to allow reinstallation-reactivation. Here’s their chat link — McAfee support — contains the link to chat

If you don’t have McAfee then Windows update KB2705219 might also be a cause as uninstalling that has appeared to fix the problem for some users. To uninstall an update — Control panel, Programs & features, [left-hand side of the window] View installed updates. Wait until the system has finished searching for the list of updates. Select required update then right-click & Uninstall.

4 solutions to fix Internet connection problems

1. Install the latest network drivers
2. Check your IP settings
3. Change the channel width
4. Run the Internet Connections troubleshooter

Windows 10 is now released and downloaded by millions of users. So now when the hype nearly passed, we have to focus on the possible problems that Windows 10 brings with itself.

One of the most annoying problems which certainly needs to be solved as soon as possible is the ‘no internet connection’ issue. In this article, I’m going to show you what to do if you cannot connect to internet in Windows 10.

What to do if you can’t connect to the internet

1. Install the latest network drivers

Outdated network drivers are frequently the cause of most Internet connectivity issues. As such, update them as soon as possible.

This can be easily done with a third-party driver updater, and the best on the market is DriverFix.

Simply download it, run it, and let it automatically scan for any missing, broken, or outdated drivers. You will then get to choose what to do with each and every one of them.

All in all, if you love programs that do the work for you, then you can rely on DriverFix.

2. Check your IP settings

Here’s how to enable IPv4 and IPv6 protocols:

1. Go to Search, type network and open Network and Sharing Center
2. Go to Change adapter settings from the left pan
3. Right click on your connection device (in most cases it’s called just Ethernet) and go to Properties
4. Under This connection uses the following items: check Internet Protocol Version 4 (TCP/IPv4) and Internet Protocol Version 6 (TCP/IPv6)
5. Click OK and restart your computer

When you turn your computer back on, you should be able to connect to internet without any problems.

There’s a chance that Windows 10 turned off your IPv4 and IPv6 protocols after the installation, this doesn’t happen very often, but it could happen. So logically, all you need to do to get your internet connection back is to turn on these protocols again.

Sometimes, your IPV6 may be enabled but not working. Re-enabling it should fix this issue.

3. Change the channel width

1. Navigate to Network and Sharing Center from the list of results
2. Go to Change adapter settings
3. Select your wireless adapter by right-clicking it > go to Properties > Go to Configure
4. Select the Advanced tab > select the 802.11 channel width and change the value. Keep using a different value until you’ve established a stable internet connection.
5. Save your new settings.

This step applies to wireless networks. By changing the bandwidth settings, you allow your computer to use other wireless frequencies and expand its reach.

4. Run the Internet connections troubleshooter

Windows 10 also comes with a built-in troubleshooter that automatically identifies network issues and errors.

Go to Settings > Update & Security > Troubleshoot > run the Internet troubleshooter.

If you have any other Windows 10-related issues you can check for the solution in our Windows 10 Fix section.

How To Fix An Intermittent Internet Connection In Windows 10

Get down off the ledge and instead try these options

Few things are as frustrating as having to deal with an intermittent internet connection that keeps disconnecting and reconnecting. Maybe you’re working on an urgent task, binging on your favorite program on Netflix, or playing a heated online game, only to be abruptly disconnected for whatever reason.

In this guide, we’re going to show you the usual suspects behind a bad internet connection and possible solutions that can resolve the problem.

What Causes Intermittent Internet Connections

An intermittent internet connection is often a result of several issues:

• Physical or electronic interference from devices such as cordless phones or other electronics large metal objects and electrical equipment like TVs, microwaves or home entertainment electronics.
• Wireless networks running in your area at the same frequency.
• Physical obstructions such as floors, appliances, walls, furniture and more can cause interference, especially where wireless signals pass through them.
• Corrupt Windows system files
• Problems caused by Windows updates
• Faulty network card in your computer or outdated drivers
• An overheating modem
• Issues with your Internet service provider
• Virus or malware infection
• Software conflicts

Fixing An Intermittent Internet Connection In Windows 10

1. Move closer to the WiFi router or hotspot
2. Disconnect some devices connected to your WiFi
3. Move WiFi devices away from other transmitting devices
4. Power cycle your router
5. Check service alerts
6. Check with other devices
7. Network Card failure
8. Corrupted Windows system files
9. Malware or Virus infection
10. Security software conflicts
11. Run Network Troubleshooter
12. Hide Windows Updates or driver updates
13. Network Reset

Move Closer To The WiFi Router Or Hotspot

You can do this whether you’re at home or have a portable computer at your workplace if you know where the WiFi router or hotspot is positioned.

If you are in a location where there could be many different wireless networks, it’s probably a good idea to use a WiFi scanner app and change your Wifi channel to something else.

Disconnect Devices Connected To Your WiFi

When multiple devices are using your WiFi all at once, there’s not enough bandwidth for each device, so disconnecting some of them can improve performance on your computer.

This is especially true if you have a lot of smart home devices connected like digital assistants, indoor and outdoor cameras, etc. Another option is trying to switch your device to a wired Ethernet connection rather than slower WiFi.

Move WiFi Devices Away From Other Transmitting Devices

When wireless devices such as cordless phones, Bluetooth devices, baby monitors, and others are closer to each other, they all try to send data over the air. Moving them away from other transmitting devices or turning them off when you’re not using them can help improve your connection.

Power Cycle Your Router

If your router can’t maintain a steady connection, check if it’s overheating and power it off until it cools down, or try power cycling it and see if the connection improves.

Also, if you’re using the cable modem provided by your ISP instead of your own and you’ve had it for longer than 6 months or 1 year, it’s not a bad idea to call them and ask them to replace it. Those devices are usually really cheap and last a very short time in my experience.

Check Service Alerts

Your intermittent internet connection may be due to issues with your ISP. Check the service alerts for your area and see if it’s one of those affected before concluding that it’s an issue with your router or your device.

Contact your ISP to see if the problem is on their end. They can run system and line checks to determine whether there’s any issue between them and your computer, and suggest possible fixes for the connection problem.

Check With Other Devices

If you have another computer or device that uses the same internet connection, test whether the connection is stable on those devices. If they also have the same issue, it could be a problem with the router or modem, or your ISP.

If it’s only with the device you’re currently using, check for hardware failures or operating system issues, which are common causes of internet connection problems.

Network Card Failure

Your computer’s network card may struggle keeping a steady internet connection. You can fix it by reinstalling the network card drivers.

To do this, right-click Start > Device Manager. Click Network Adapter to expand the category, right-click on your network card and select Uninstall. Restart your computer and allow Windows to reinstall the card and its drivers.

You can also check the network card manufacturer’s website for updated device drivers, download and install them to your computer. Reboot your computer and test your connection again.

If you have a removable network card and know how to go about re-seating it, you can remove it and insert it back into the PCI slot to ensure it is seated firmly in the slot. Once done, return everything back to its usual place, plug in the power cord and power on your computer. Test whether the connection is stable.

Corrupted Windows System Files

Internet connectivity issues can be caused by corrupted Windows operating system files. Try running the system file checker first to see if anything comes up. You can also perform a system restore to replace the corrupt files with clean ones and then check your internet connection again.

Malware Or Virus Infection

An intermittent internet connection could also be caused by a virus or malware infection on your router or computer. If it’s severe, it may not even work, but the remedy is to use the best antivirus available that can nuke any virus or spyware, and stabilize your connection.

Security Software Conflicts

Your security software programs like antivirus or firewall may interfere with your internet connection. To resolve this, check the settings for either program and see which ones are enabled. Try to disable them temporarily and see if your internet connection stabilizes.

If it does, check with the antivirus manufacturer if the setting is important for your device’s protection. If it’s not, you can leave it disabled for an improved internet connection.

Run Network Troubleshooter

The Network Troubleshooter helps diagnose and fix the usual internet connection issues, but you can check whether there’s an underlying cause to the bad connection you have.

• To do this, click Start > Settings > Network & Internet.

• Next, click Network troubleshooter under Change your network settings and follow the prompts to see if the problem is resolved.

Replace Your Modem Or Router

If restarting your router didn’t work, a more in-depth solution is to reset your wireless router. This is a bit more involved as you have to setup all the WiFi settings again, but could fix the issue.

If you’re still experiencing a bad internet connection after trying the suggestions above, your network card, router or modem may be defective. In this case, get a new router, modem or network card and see if the connection is better.

Hide Windows Updates Or Driver Updates

If you can’t download and install a new network adapter driver, you can hide the Windows Update that caused you to lose your network connection. In Windows:

• To do this, go to Control Panel > Programs > Programs and Features and click View Installed Updates.
• Select the unwanted update you want to uninstall from the list and click Uninstall.

You can also download the Wushowhide troubleshooter to hide the problematic updates. Check whether the internet connection stabilizes after uninstalling the update. To reinstall it, go to Settings > Update & Security > Windows Update > Check for Updates.

Network Reset

If the steps above don’t help, reset your network as a last resort. This can solve internet connection issues especially after upgrading from a previous version of Windows to Windows 10, or when you can’t connect to shared network drives.

A network reset uninstalls and removes network adapters you may have installed, plus their settings. Once you restart your PC, the network adapters will be reinstalled, and their settings set back to default.

Note: You need Windows 10 version 1607 or later to use network reset. Check your version by going to Start > Settings > System and click About.

• To reset the network, click Start > Settings > Network & Internet.

• Click Status and then click Network Reset.

• In the Network reset screen, click Reset Now and then click Yes to confirm the action. Allow your PC to restart before checking your internet connection again.
