Many users are familiar with the situation where the Wi-Fi indicator is on but there's no internet access. Instead of accessing the usual websites, the browser displays an error, and the system reports the status as "Limited" or "No internet access." This state means that a physical connection to the router is established, but data exchange with the outside world is not taking place.
The reasons can be completely different: from a banal failure in the router to incorrect settings of security protocols on adapter your computer. Often the problem lies in an IP address conflict, when two devices try to occupy the same space on the network. Outdated devices also cannot be ruled out. drivers or operating system software failures that block normal packet transmission.
Before attempting complex manipulations, it's important to rule out basic factors. Restarting the hardware often resolves up to 80% of such issues, as it clears the cache and redistributes network resources. If simple methods fail, a more in-depth diagnosis of TCP/IP settings and power saving parameters will be required.
Diagnostics and initial reboot of equipment
The first step should always be to diagnose the current network condition. Windows provides built-in troubleshooting tools that can automatically fix some errors. Right-click the Wi-Fi icon in the system tray and select "Troubleshoot." The system will check for any problems. addressing conflicts and default gateway status.
If automatic search doesn't help, we'll try a hard reset. Routers, like any computer, have limited RAM, which eventually becomes overloaded with temporary data. This causes the DHCP server to freeze, stopping issuing new addresses to devices. To fix this, you need to completely power off the router.
Unplug the power cord and wait at least 10-15 seconds. This time is necessary for the capacitors to discharge and the device's temporary memory to clear. After turning on, the router will take about a minute to fully boot up and re-establish a connection to the ISP. Only after all the indicators light up should you try connecting again.
⚠️ Important: If your router is leased from a provider, be sure to check the terms of your contract before performing a factory reset (press the Reset button). A reset may delete PPPoE or VLAN authentication settings, requiring reconfiguration by a specialist.
Reset network settings and TCP/IP parameters
The most common software cause of this error is the accumulation of errors in the TCP/IP protocol stack. The operating system maintains a DNS cache and routing tables that may contain outdated or incorrect entries. To clear them, you will need to run the command prompt with administrator rights. Win + X and select the appropriate item from the menu.
In the window that opens, you need to enter several commands sequentially. Each command handles a specific cleaning step: from resetting Winsock to updating the DHCP client. Enter the commands one at a time, waiting for a success message. This will force the system to re-query all the necessary parameters from the router.
ipconfig /flushdnsipconfig /registerdns
ipconfig /release
ipconfig /renew
netsh winsock reset
After running the last command, the system will prompt you to restart your computer. Don't ignore this request, as changes to the registry and network drivers only take effect after the restart. During the restart, Windows will reinstall virtual network adapters, which often resolves software conflicts.
☑️ Network Reset Checklist
Updating and reinstalling Wi-Fi adapter drivers
The software that controls your network adapter may not function correctly after a major Windows update or installing a new antivirus. The driver is the intermediary between the hardware and the operating system, and if it contains bugs, the connection will be unstable. You can check the driver's status via device Manager.
Find the "Network Adapters" section in the list and select your wireless module (usually listed as "Wireless," "Wi-Fi," or "802.11"). Right-click and select "Uninstall device." Don't worry about the adapter disappearing forever—after a reboot, the system will automatically detect the hardware and install the standard driver.
However, for maximum performance, it's best to download the latest version from the official website of your laptop or motherboard manufacturer. Pay attention to the chipset version, as identical laptop models may use different modules. Intel, Realtek or QualcommInstalling the correct driver often solves connection problems.
⚠️ Note: When uninstalling a driver, the confirmation window may check "Delete the driver software for this device." If you don't have the installation file handy or internet access on this PC, it's best to leave this checkbox unchecked so Windows uses the saved copy.
What to do if the driver is not found?
If the automatic search doesn't yield results, use another device (smartphone or another PC) to download the driver. Transfer the file via USB cable or Bluetooth and install it manually.
Configuring adapter power settings
Modern operating systems aggressively optimize power consumption, which often results in the Wi-Fi module being disabled to conserve battery life. As a result, the adapter doesn't wake up quickly when a request arrives, and the connection is dropped or marked as limited. This can be resolved in the device properties.
In Device Manager, go to the properties of your wireless adapter and open the Power Management tab. Here, uncheck "Allow the computer to turn off this device to save power." This will force the adapter to run in constant mode, which will eliminate delays when reconnecting.
It's also worth checking the power plan in Control Panel. Select "High Performance" mode to prevent the system from throttling the processor and network cards. This is especially important for laptops running on battery power, which have strict power consumption limits enabled by default.
| Parameter | Default value | Recommended value | Impact on Wi-Fi |
| :--- | :--- | :--- | |
| Power Saving | On | Off | Connection Stability |
| 802.11n Mode | Enabled | Enabled | Transfer Rate |
| Roaming Aggressiveness | Medium | Low | Connection Priority |
| Throughput Booster | Disabled | Enabled | Response Speed |
IP address conflicts and static addressing
Each device on a local network must have a unique IP address. If the router mistakenly assigns the same address to two devices, or if you manually assign an address that's already in use, a conflict will occur. The system will detect the duplicate address and restrict network access for one of the devices to protect data integrity.
Most often, the problem is solved by automatically obtaining addresses. Go to the protocol properties. Internet Protocol version 4 (TCP/IPv4) Make sure the "Obtain an IP address automatically" and "Obtain DNS server address automatically" boxes are checked. This will allow the router's DHCP server to distribute addresses automatically without errors.
If automatic IP allocation doesn't work, you can try manually entering a static IP address. Use a range that isn't in the router's automatic allocation pool (for example, if the router allocates 100 to 200, select 50). This will help avoid conflicts in the future.
ipconfig /release
ipconfig /renew
These commands, entered in the command line, will forcibly release the current IP address and request a new one from the server. If the problem was a stuck IP address, this action will immediately restore internet access.
The impact of antiviruses and firewalls
Third-party antivirus programs often have their own firewall modules, which can be overly aggressive. After updating their signature databases or the program itself, the antivirus may begin blocking legitimate network connections, deeming them suspicious. This results in a "Restricted" status.
To diagnose the issue, try temporarily disabling your antivirus software. If you can connect to the internet, the problem lies with your security settings. Find the network section in your antivirus settings and add your home network to the trusted list.
It's also worth checking the built-in Windows firewall. Sometimes the rules for public networks get confused. Make sure your network is defined as "Private" and not "Public," as public networks have stricter access restrictions.
Provider-side issues and MAC filtering
Keep in mind that the problem may not be with your computer, but with your ISP's equipment or router settings. Some ISPs use MAC address binding. If you've changed your computer or network card, your router may block the new device unless MAC address cloning is enabled.
Your ISP may also limit the number of connected devices or use specific DNS settings. In this case, changing the DNS servers in your adapter settings to public ones, such as Google's, can help (8.8.8.8) or Cloudflare (1.1.1.1). This often bypasses local name resolution errors.
Check the connection cable (if using the WAN port) and the router's indicator lights. If the error light (often red or a flashing globe) is lit, it means there's no signal from the ISP. In this case, local computer settings won't help, and you'll need to call technical support.
⚠️ Note: Router interfaces and menu item names may vary depending on the model and firmware version. If you are unsure, consult the official instructions from your equipment manufacturer.
Frequently Asked Questions (FAQ)
Why does Wi-Fi say "Limited" but the internet on my phone works?
This indicates a problem with your computer's settings or drivers, as the router is working properly and is distributing internet to other devices. It's worth checking the TCP/IP settings and Wi-Fi adapter drivers on the affected PC.
Can a virus block internet access?
Yes, some types of malware change proxy or DNS settings, redirecting or blocking traffic. Check your LAN settings and run a full system scan with an antivirus program.
How to reset all network settings in Windows 10/11 in one step?
Windows 10 and 11 have a built-in feature: Settings → Network & Internet → Status → Network Reset. This will delete all saved Wi-Fi passwords and restore your network settings to factory defaults.
Will replacing the antenna on a router help if the connection is limited?
Replacing the antenna will only help if the problem is a very weak signal (low RSSI), causing packet loss. If the signal is strong but there's no internet, the problem is software configuration, not hardware.
