It can be extremely aggravating when you have the “Wifi is enabled, but there is no network connectivity” issue. The modem or the operating system could both be at fault. We’ve seen the “No internet on connected Wifi” issue quite frequently over the years, so we decided to compile a thorough guide to help you solve it.


Why Does The Error “AT&T WiFi Connected but No Internet Access” Occur?

Connecting additional devices, such as a mobile phone, to the router’s WiFi network can help pinpoint its malfunction. If other devices can connect to the Internet without issue, the issue must be with your computer’s WiFi adapter. However, if other devices are also unable to connect to the Internet, the issue is likely to be with the router or the Internet connection.

When the Internet Connection is Unreliable

Even when WiFi is active, there are times when the issue is with the Internet network rather than a specific device. Anything beyond your control, such as a wire cut or a service interruption, could be at fault.

You must therefore determine whether your ISP is to blame for the problem. To do this, make sure the modem’s “Internet” indication light is on. The power and DSL indicators should be on. Check to see if anything unusual is occurring, such as unexpected changes in the lighting.

Immediately contact your ISP if the lights are out or fluctuating.

Problem in the device

The issue lies with the device and its WiFi adapter if other devices can connect to the Internet using your WiFi.

Check whether rebooting your device will help first. Similar to the router, network and software issues are usually immediately resolved with a quick restart.

DNS Cache Related Conflict

A DNS cache stores information about all recent website traffic so that it can quickly load website content for you.

When you enter a URL in your browser, the operating system typically checks the DNS cache. The system software pulls these pages out from the cache rather than downloading them from the Internet if your query matches those that are available in the cache.

Several factors, such as software viruses and other malicious code that inserts domain names without permission, can cause DNS caches to become skewed. On some websites, banners and ads may have malicious code that can harm your DNS cache.

An incorrect IP address results in an incorrect DNS cache that prevents you from connecting to the Internet. The DNS cache can indeed be cleared to resolve this.

Out of Date Wireless Modes

Internet speeds and coverage are impacted by the wireless mode and standard that your router uses. Standards like 802.11n, 802.11b, 802.11g, and 802.11ac are frequently seen. These standards are set by IEEE to ensure cross-brand and cross-type router interoperability.

The oldest and slowest of them is 802.11b, while the newest and fastest is 802.11ac. Let’s say your router is based on the most recent 802.11ac standard, but your device can only connect to 802.11b or 802.11g. The device is incompatible with the current standard, which creates difficulty.

IP address conflict

The term “IP address dispute” refers to the circumstance that occurs when numerous network nodes are assigned the same IP address. When this happens, every device’s internet connection is lost.

Despite their rarity, IP address problems can happen under certain circumstances.

  • An IP address collision occurs when two or more devices share the same IP address.
  • An IP address from static range is given to one device by the DHCP server, and that exact address is then given to another device on the network.
  • Other networked devices can access a computer’s IP address when it enters hibernation. As a result, there is a conflict when the laptop is turned back on.
  • Interference nearly always occurs when several wireless routers are connected to a single network.

Outdated network driver

A broken or out-of-date network driver may be the cause of WiFi being enabled without an Internet connection. There might be a problem if the name of your network adapter or device has a small yellow exclamation mark next to it. If none of the previous options have worked, you should try this even though the “yellow mark” isn’t there.


[Fixed] AT&T WiFi Connected but No Internet Access

Solution 1: Confirm Whether AT&T Service Is Down

If your WiFi light is on but none of your gadgets can connect to the internet, the problem is likely caused by a temporary disruption at your ISP. This should be checked before you go resetting everything and rearranging the cables.

To check if an outage is reported in your location, turn on your cellular data and visit the customer-facing website or social media pages of your internet provider. Down Detector and similar sites aggregate outage data and may have the answer you’re looking for if you can’t find it here.

Of course, you can always phone your ISP and ask whether there is an issue with their service in your area that is preventing you from accessing the Internet.

Solution 2: Restart Device

We know how silly this may sound, and I’m willing to bet that most of you have already tried it a few times.

Can you try powering it down and then back up again? A remedy so obvious that it’s become a cliche. When you don’t have access to the internet, though, the remedy is straightforward. Stop using the internet and disconnect your router from the wall if you only have a router and no modem. Let it sit for a minute, then try turning it on again.

If you are using a modem as well as a router in your house, switch them off and keep them disconnected for a while. Then connect the modem first, followed by the router a minute later. It normally takes around five to 10 minutes for these gadgets to reboot and power back up again. Once you’ve done that, double-check to see if everything is still linked.

This is one of the best and most reliable solutions to the “no internet connection” problem at home. However, there are situations when not even this helps. The next step, then? Moving on to the third stage now.

The network devices must reboot to reload their settings and update their IP tables.

Solution 3: Check Modem Indicator Lights

Your network connection might be the problem rather than the devices themselves. Check to see whether the WAN indicator is blinking on the router. Verify that the WAN signal isn’t flickering erratically or not lighting up at all.

The Wifi lights should be flickering, and the DSL lights ought to be ON or green. Checking this out on your own could be difficult, so calling your internet service provider’s support line is your best bet if you want to make sure the problem is still happening. Ask them how much time will it take to solve the problem.

Solution 4: Check If The ISP Is Down

Use mobile data to access Downdetector and search for your Internet provider. Suppose AT&T is responsible. You can check the most well-known provider of internet services here to see whether there is a server outage or downtime. This useful tracker allows you to confirm coverage in your precise area.

Click the Live Outage button to see whether it’s down right now in your region. To see whether other subscribers are reporting issues with

Solution 5: Antivirus or Similar Security Applications

Antivirus software is known to interfere with web connections. Turn off your antivirus and other security software for a while to see whether the “Wifi connection but no internet issue” gets fixed. In that scenario, you are aware of where to focus your search. If not, move on to the next step.

To make sure you haven’t installed any malicious software that is causing this issue, you should also run a thorough scan with your antivirus program and Malwarebytes.

Solution 6: Check Your Router Settings To Ensure Your Permissions are Correct

When neither your service provider nor your router is at fault, troubleshooting your network permissions should be your next step if you still can’t access to the internet. Media Access Control (MAC) identities are used by every home Wi-Fi network to determine which devices are authorized to connect to it. It can force-reboot your devices if the necessary permissions aren’t in place. You must therefore determine if this system is set to “approve” or “deny.”

  • If you’re having trouble connecting to the internet, try these steps:
  • Find the Windows key on your keyboard and hit it. When a search bar appears, enter “cmd.”
  • Right-click the Command Prompt application and choose “run as administrator” to accomplish this.
  • The command prompt can be accessed by repeating the right-click process. Go ahead and press the Enter key after typing “ipconfig” into the command prompt.
  • The IP address of your default gateway should now be visible. It will produce a figure similar to this: 192.168.X.X. Keep this number.
  • To call this number, open a web browser, type or copy and paste the number into the address bar, and hit the enter key. It should now be possible to access the router’s administration interface.
  • Nonetheless, you’ll need to log in before you can use this control panel. These are not the same credentials as your WiFi network’s login information. Where did you discover this data? The username is typically displayed on the router’s back. There’s a good probability that “admin” is the default password for your router if you haven’t changed it.
  • You should now be able to access the configuration menu. Find the option to restrict access based on MAC address. Verify that it has been turned off, or that you’re not accidentally blocking access with a filtering rule that you never intended to activate.

Solution 7: It’s Time for a Network Reset

You have probably already tried unplugging, restarting, and checking your connections. If you’ve exhausted these steps and are still experiencing “no internet connection,” a network reset is usually the next best option. Having trouble connecting to the internet? Try restarting your network settings.

  • Type “settings” into your browser’s search box.
  • Find the menu item labeled “network and internet” and choose it.
  • There ought to be options on the left side of the screen. Find the “status” menu item and choose it.
  • Locate the “network troubleshooter” menu item and choose it to launch the tool.
  • Options to “Network Reset” should be available.
  • In order to reset all your devices and network settings, click the “network reset” button and follow the on-screen prompts. After you’ve done these things, click the wifi icon, check that your network is listed, and then connect to it.

Solution 8: Use a Built-in Troubleshooter

If at least one of the additional devices connected to the network is able to access the Internet, but the device with a Wifi adapter problem is unable to, then the router is indeed the cause of the problem. If you’re using Windows or a Mac, simply use the system’s built-in troubleshooter to fix the issue.

When you right-click the network icon in the taskbar, a menu will display where you may choose “Troubleshoot issues.” Windows will automatically check for and fix network problems. A diagnosis of the issue will be provided if repair is not possible. If you can’t find the answer here, try searching the web or asking in the discussion thread.

Solution 9: Update your network adapter driver

If you often update your OS but fail to update your hardware component, there can be a communication problem between your computer and your network adapter.

For this workaround to succeed, a functional internet connection is required while we urge Windows to upgrade your WiFi network adaptor. By connecting an Ethernet cable to both your desktop and your network or modem, you may confirm that you have a working internet connection.

If your WiFi card’s driver needs updating, try these steps:

  • You may find the device manager by searching for it in your computer’s search bar.
  • Find “Network adapters” and drag it down to see the list.
  • In the enlarged list, right-click the WiFi adapter you wish to manage.
  • Select the Driver Update tab.
  • Either the adapter will specify that it is for a wireless connection, or it will identify a wireless mode, such as 802.11.

You may need to manually install the latest driver on your computer if it does not do so automatically. You’ll need to connect to the internet in order to do this again, so you’ll need to use an Ethernet cable or switch to a device that can connect to the internet.

The next step is to manually install the most up-to-date driver on the computer that has WiFi connected but no internet access by visiting the website of the motherboard maker or the WiFi card manufacturer and downloading the driver from there.

Solution 10: Reboot Router

This setting will resolve any problem you may be experiencing with your router. You can reboot the router to its factory settings to undo any modifications that might be the root of the issue. This calls for you to change your router’s password and a few of the default options once more.

Although a reset can be started using the router’s settings, hitting the reset button directly is considerably easier. The reset button is generally hidden in a small hole on the router, so you will need to carefully scrutinize the device to find it. Using a paper clip or mobile SIM tray, locate the key and hold it down for 5 to 15 seconds, or until all the lights flicker and the router restarts. You ought to be able to make a connection once the router has finished rebooting.

A bad network driver could be the cause of a broken connection. By pressing the Windows key along with R and typing “devmgmt.msc,” you may access Device Manager.

Pull up the Network Adapters menu and locate the wireless card you’re using. Any brand you choose should include Wireless Network Adapter after the label name. If you right-click the network card, a menu will appear where you may choose “Update drivers.”

There are currently two options. You have the option of manually updating drivers or automatically updating drivers (online). Connect your PC to the network switch using an Ethernet cable. As long as your router and internet connection are working properly, you should be able to connect without any problems. Once everything is connected, choose the option to have Windows automatically find and install the most up-to-date driver for your machine.

You will need to manually download the most recent driver from the manufacturer’s website using another device in case you are unable to access it and then copy it to your computer. Select “Browse my computer for driver software” and carry out the manual installation process after obtaining the most recent driver.

Solution 11: Call the ISP

If your ISP also supplied your router and modem, they are responsible for making sure you can always access the internet. If the above solutions failed to resolve the issue, you should contact your Internet service provider (ISP). They ought to be able to give you step-by-step instructions over the phone if you have an issue. If they are unable to solve the issue over the phone, you can request that an agent be dispatched to the location of the device for a more in-depth look.
