If your computer won’t connect to the internet while other devices do, the issue is almost always local to your machine – often related to network settings, adapter problems, or software conflicts. By checking your Wi-Fi status, updating drivers, resetting network configurations, and verifying physical connections, you can usually restore internet access quickly and smoothly.

Key Takeaways
- Check your computer’s Wi-Fi and network adapter status carefully, including hardware switches and power settings. [1]
- Reset or update your network drivers and configurations to resolve common software or configuration glitches.
- Check physical connections and adjust router settings to rule out hardware issues and ensure the network allows your device.
1. Verify Wi-Fi and Network Status
Credits: Ask A Computer Geek
It’s funny how one stubborn computer can throw the whole office off, even while every other device is humming along online. We’ve received calls from people staring at the “No Internet” sign next to their clock, shaking their heads at how their computer won’t connect to the internet but others will – and with good reason. It feels personal, even though it isn’t. Our first thought? Always start simple. It could be the tiniest thing.

1.1 Check Wi-Fi and Airplane Mode Settings
People don’t always realise laptops sometimes carry a small switch that turns Wi-Fi off entirely. If you’re using a Windows device, look for a Wi-Fi symbol key along the top row, often paired with the “Fn” key. Flicking the switch, or pressing that key, fixes a lot.
On desktops with a USB or PCIe wireless adapter, check that nothing’s come loose at the back. For Airplane Mode, glance at your system tray or menu bar: is it switched on? This one blocks all wireless adapters, no matter what you try.
Now, skim the list below for what we regularly check with clients in person or over the phone:
- Is the Wi-Fi turned on (check with hardware switch or function key)?
- Is Airplane Mode definitely off?
- Are you connected to the right Wi-Fi network – matching the one everybody else uses?
- Did you enter the correct Wi-Fi password? Sometimes it’s changed and not updated on your machine.
A lot of embarrassment is avoided just by re-typing that Wi-Fi password carefully or picking the correct wireless network from the list.

1.2 Inspect Network Icon and Error Messages
The network icon is not just decorative, it’s telling the whole story if you look. Some see a yellow triangle with an exclamation mark, others a red “X” or just a spinning symbol that never seems to stop. If your computer says “Connected, no internet” or reports limited connectivity, jot down the exact message you see or snap a quick photo. That’s information we use when diagnosing the next step.

1.3 Run Network Troubleshooter
Built-in tools do repair more than their reputation suggests. On Windows, right-click that network icon and select “Troubleshoot problems.” It’s straightforward, sometimes surprising you by flipping a broken connection back on in minutes. On Mac, search for “Wireless Diagnostics” and let it run. There’s a reason this step is first for us on most calls – we’ve seen it fix dodgy settings, disabled adapters, and weird IP address issues in a flash.

2. Network Adapter and Driver Checks
Sometimes, everything looks right on the outside, but the computer won’t connect to the internet. We get a lot of these cases – especially after major Windows or macOS updates.

2.1 Confirm Network Adapter Status in Device Manager
If the adapter’s disabled or missing, your computer won’t join the internet, no matter how strong the signal. We use Device Manager on Windows:
- Expand “Network adapters” to see if your Wi-Fi device is listed.
- Any device with a down arrow is disabled; a yellow exclamation mark means trouble (usually drivers).
- If your wireless adapter isn’t there at all, it might be a hardware or BIOS issue.
A quick enable, update, or uninstall/reinstall often works. We’ll right-click the adapter, enable it if disabled, or reinstall if it looks suspicious.

2.2 Update, Roll Back, or Reinstall Network Drivers
Driver errors rank high on our list of “usual suspects.” If your computer lost its wi fi connection after a driver or system update, try rolling back to the previous driver version. If everything suddenly broke, update through Device Manager, or, failing that, fully uninstall the adapter and let Windows reinstall upon reboot. Mac users can check for software updates or re-add network adapters in system preferences. [2]

2.3 Verify Hardware Switch and Power Settings
On some machines, a tiny slider or button (sometimes hidden near a laptop’s edge) controls wireless power. Function keys are another culprit – often toggled by accident. We always have clients check, because a bumped switch wastes more time than you’d think. Also, pop into Advanced Power Settings (found through Control Panel or power icon) and make sure “Allow the computer to turn off this device to save power” is unticked for the wireless network adapter.

3. Reset and Reconfigure Network Settings
There’s something liberating about wiping the slate clean and letting the system rebuild its network preferences. On plenty of service calls, this step has turned things around.

3.1 Reset Network Configuration
- In Windows, head to Settings > Network & Internet > Status and choose “Network Reset.” This will remove and reinstall all your network adapters.
- On Mac, go to System Preferences > Network, remove the Wi-Fi adapter, and add it back.
Clients in busy offices love how this avoids fuss – no need to hunt for individual problems, just tear it down and set it up fresh.

3.2 Forget and Reconnect to Wi-Fi Network
Saved profiles sometimes go sour. We recommend:
- Removing your Wi-Fi network from the saved list.
- Rejoining and re-entering your password.
This sidesteps strange errors involving outdated credentials or changed router settings. It also forces the system to treat your computer won’t connect to the internet like it’s brand new – usually resets hidden problems.

3.3 Reset Network Stack via Command Prompt
There’s a laundry list of handy commands for nerdier users:
- “netsh winsock reset”
- “netsh int ip reset”
Run these in Command Prompt as administrator. Most people don’t bother, but we often see them rescue stubborn configurations. Don’t forget to reboot.

4. IP Address and DNS Configuration
A flash of insight sometimes hits when we spot two machines with the same IP. Could be your computer, another device, or even a printer, all given identical addresses by accident – conflict.

4.1 Ensure Automatic IP and DNS Settings
Most home and small business setups run best with everything set to automatic. We do this for a reason:
- Open Network and Sharing Centre (Windows).
- Go to your active network’s Properties.
- Double-check IPv4 is set to “Obtain an IP address automatically” and “Obtain DNS server address automatically.”
Anything else can introduce conflicts, especially on networks with a lot of visitors or older hardware.
For command-line warriors:
- Type “ipconfig /release” and “ipconfig /renew” in Command Prompt.
- This gives your computer a new lease on addressing, so to speak.

4.2 Change DNS Server Address (If Needed)
DNS issues masquerade as broader network problems. For clients stuck in endless “connecting…” but able to ping IPs, we’ll set their DNS to public servers:
- Google: 8.8.8.8 and 8.8.4.4
- Cloudflare: 1.1.1.1
A small tweak here solves a wide range of mysterious loading failures, especially after ISP maintenance days.

5. Physical Connection and Router Checks
Sometimes a problem’s in the cables or router itself. We see more than a few Ethernet cables kicked loose, or routers that just need to take a breather.

5.1 Test Wired Connection with Ethernet Cable
When Wi-Fi is out, it’s time for hardwire:
- Plug an Ethernet cable directly from your computer to the router or gateway.
- Check if the network icon shows you have internet access.
If this works, your issue is local to the computer’s wireless adapter, not your whole internet connection.

5.2 Inspect Router and Gateway Device Settings
Routers can block a single computer in a dozen small ways:
- Restart the router and modem by unplugging them for at least 60 seconds.
- Check if your computer appears as a connected device in the router settings; some devices get listed as “blocked.”
- See if MAC address filtering or parental controls are enabled – you might need to whitelist your device.
One case at a restaurant in Marrickville stands out. Every POS terminal worked except one. A peek at the router showed it sitting in the “denied” list after a previous staffer fiddled with device controls.

6. Software Conflicts and Security Settings
On any given day, we get called out for issues tied to software rather than the network itself.

6.1 Disable VPN, Firewall, and Security Software Temporarily
VPNs and security software sometimes block internet access even when set to “automatic” mode. We ask clients:
- Switch off VPN and check if the network springs to life.
- Turn off your firewall or security suite just for a few minutes.
If your page loads now, it’s time to tweak your firewall settings instead of the router.
6.2 Check for Background Network Services and Updates
Windows updates, backup synchronisations, and antivirus scans can drown a machine’s connection. A check in Task Manager or Activity Monitor shows what’s running in the background.
Recently, we saw an architect’s laptop “freeze” during client calls every Friday afternoon – after some poking, we pinned it to large, timed Dropbox syncs that hogged all outbound bandwidth.
7. Advanced Troubleshooting and Diagnostics
When all the basics fail, we bring out the deeper tools – these steps sort rare or sticky cases.
7.1 Use Command Prompt for Network Diagnostics
- Open a command prompt and enter “ipconfig /all” to view details.
- If your IP address starts with “169,” your adapter isn’t talking to the router.
- Use “ping” and “tracert” commands to check where your connection fails.
This isn’t just nerd trivia, it’s practical – lets us quickly see where the blockage lies.
7.2 Identify and Resolve IP Address Conflicts
Routers sometimes assign the same address twice, or manual settings overlap. We check:
- Router-connected devices for repeat IP addresses.
- Change your computer’s settings to automatic, or set a specific, unused address.
- Restart both computer and router after adjustments.
8. Additional Considerations for Stable Connectivity
After every fix, we check for things that might trigger future issues. No sense patching something just to have it break again.
8.1 Manage Power Settings Affecting Network Adapters
Sleep and hibernation are great, until your network adapter fails to wake. We look in advanced power management and untick any setting that lets Windows “save power” by turning the adapter off. This one step has stopped dozens of “disconnect after sleep” problems for clients.
8.2 Recognise Hardware Limitations or Failures
Wi-Fi adapters, especially USB dongles and older internal cards, don’t last forever. If every other test fails, we plug in a spare device. If it connects instantly, you know there’s a hardware fault at the heart of things. Sometimes it’s age, sometimes wear, sometimes just a cheap adapter running out of steam.

FAQ
Why does my computer lose connection to the wi fi network while other devices stay online, even though the same wi fi router is being used?
There are cases where a computer experiences wi fi connection issues even though multiple devices on the same wi fi network have no problems. This can happen due to local factors such as a failing wi fi adapter, problems with the network adapter driver, or outdated network drivers. Sometimes, advanced power settings or even a hardware switch on your laptop can turn off the wireless adapter to save battery.
Checking device manager for disabled adapters or running the network troubleshooter might highlight something missed. Occasionally, the computer’s network configuration requires a reset using the “type netsh winsock reset” command in command prompt, which can help restore internet connectivity quickly.
How can ip address conflicts in my home network cause only my computer to have internet connection issues while others work fine?
If your home network assigns the same ip address to more than one device, your computer might experience internet connectivity issues, even when other devices are still working. These conflicts happen, especially in networks with many connected devices or custom network settings.
If your computer isn’t set to obtain an ip address automatically in advanced network settings, there’s a greater risk for clashes. Open device manager and the network adapters section, then check all network settings and use the network troubleshooter if needed. Setting your computer to use a valid ip address and correct dns server address can fix these kinds of connection issues.
What troubleshooting steps can I take if my computer won’t connect to the internet, but a direct ethernet cable gives me internet access?
Sometimes, your wireless network fails but connecting with an ethernet cable restores internet access right away. This points to a problem with your computer’s wi fi adapter or wifi settings. Try resetting your network configuration by using the Windows network reset tool or removing and re-adding the wireless network.
Double-check the wifi password and make sure airplane mode is off. If your device connects only with ethernet, you might need to update your network adapter driver or consider replacing the wi fi adapter if nothing else works.
Can advanced security software or firewall settings stop only one computer from accessing the internet on a local network?
Yes, security software or strict firewall settings can sometimes block internet access for a single computer won’t connect, causing internet connection issues while other devices on the local network stay connected. Some security programs may block certain network equipment or ip address ranges they consider dangerous. This can also happen after installing new software or changing factory settings.
If you suspect security software is the cause, try turning it off briefly and checking if the connection returns. Don’t forget to turn it back on after troubleshooting. Use the network icon to check error messages, and make sure your default gateway hasn’t changed.
Why might running a network reset or using a command prompt tool help restore internet connectivity when only my device will not connect?
Network reset tools and command prompt commands like “type netsh winsock reset” or “ipconfig /renew” are useful when only your device faces consistent connectivity issues. Sometimes, hidden network configuration errors, outdated network drivers, or bad registry entries stop your computer from getting a stable connection.
Running these tools reinstalls network adapters, clears out old network settings, and resets your IP settings. This resolves many stubborn connection issues that aren’t affecting multiple devices or the rest of your home network, especially after software updates or internet outages from your internet service provider.
What can cause slow internet speeds only on my computer, even though all other connected devices are working fast and the same internet provider is being used?
Slow internet speeds on only one device while others on the same network or using the same internet service provider are unaffected usually points to issues with local network hardware or outdated network drivers.
Your network icon may show you’re connected, but poor performance could be due to a faulty wifi adapter, damaged power cable, or interference with the wireless access point. Advanced network settings or a network configuration error, such as the wrong dns server address, can reduce speeds. Running computer maintenance and checking both hardware and wi fi settings can help fix this kind of issue.
If my device is stuck on “Obtaining IP address” when attempting to join a wi-fi network, but other devices connect with no problem, what might be wrong?
A device that gets stuck on “Obtaining IP address” while other devices join the wireless network without issues may be facing a glitch with its network adapters or a misconfigured ip settings panel.
Check your device’s ability to get an ip address automatically and ensure your wireless adapter recognises the wi fi router. Try a network reset, update the network adapter driver through device manager, and verify the power settings don’t turn the adapter off during inactivity.
How does a reset router or gateway device affect internet connection problems on a network where only my computer won’t access the internet?
When only your computer won’t connect to the internet but others connect through the same network, resetting the router or gateway device can help by clearing out cached network issues and distributing a fresh valid ip address to all connected devices.
After a reset, double-check all network settings on your computer and ensure you use the correct wi fi password or ethernet cable. If the problem continues, focus on local network equipment, such as the network adapters section in device manager, or look for issues with your command prompt network diagnostics.
Conclusion
If you ever find yourself rubbing your head, staring at that network icon and muttering, “My computer won’t connect to the internet but others will,” don’t let it stall your whole day. The answer’s usually close – a setting, a click, or occasionally a fresh bit of hardware.
