Why does "Limited Access" appear when connecting to Wi-Fi? A full analysis of the causes and solutions.

• ✅ Connected to the router (there is a connection at the Wi-Fi level)
• ❌ Did not receive correct network settings (IP address, gateway, DNS)
• ❌ Cannot access the global network (problems at the provider or routing level)

This not an authentication error (when asked to enter a password). Here, the device "sees" the network but can't use it. Most often, the problem lies in one of three components:

Before digging deeper, check the basics:

Make sure the internet works on other devices|

Reboot your router (unplug for 30 seconds)|

Check if the Internet light on your router is on|

Try connecting via cable (if possible)-->

2. Router-side problems: top 5 causes

If all devices If the network shows "Limited Access," the router is to blame. Let's look at the most common scenarios and their solutions.

2.1. DHCP server failure (no automatic IP distribution)

The router should automatically assign IP addresses, subnet mask, gateway And DNS through protocol DHCPIf this service crashes, devices receive incorrect settings (for example, IP like 169.254.x.x).

How to check:

1. On Windows open Command line (Win + R → cmd).
2. Enter

   ipconfig /all

   and find the line IPv4 address.
3. If the address starts with 169.254 — DHCP is not working.

Solutions:

• 🔄 Reboot your router (Pull out power for 30 seconds).
• ⚙️ Enable DHCP manually:
  1. Go to the router's web interface (192.168.0.1 or 192.168.1.1).
  2. Find the section LAN → DHCP Server.
  3. Make sure the option is Enable DHCP Server included.
• 📡 Reset your router to factory settings (button Reset for 10 seconds).

2.2. Blocking the MAC address of the device

Some routers (especially TP-Link, Asus with proprietary firmware) have the function MAC address filteringIf your device is blacklisted or not whitelisted, access will be restricted.

How to check:

1. Log into your router's web interface.
2. Find the section Wireless → Wireless MAC Filtering (or Security → MAC Filter).
3. Check if filtering is enabled and if your MAC is listed.

Solution: Disable filtering or whitelist your device's MAC address. You can find the MAC address using the command:

ipconfig /all | find "Physical Address"

What does a MAC address look like?

A MAC address is a unique identifier for a network adapter in the format XX:XX:XX:XX:XX:XX (For example, 00:1A:2B:3C:4D:5E). It is assigned at the factory and does not change (unless replaced by software).

2.3. IP address conflict in the network

If two devices on the network receive the same IP address, a conflict occurs and Windows displays "Restricted Access." This may occur due to:

• 🔄 DHCP server failure (distributed one IP to two devices).
• ⚙️ Manual IP configuration on one of the devices (static IP matched dynamic).
• 📱 Connecting a device that was previously on the network with the same IP (for example, after resetting the router).

Solution:

1. On the problematic device, open Control Panel → Network and Sharing Center → Change adapter settings.
2. Right click on Wi-Fi → Properties → IPv4.
3. Check the boxes Obtain an IP address automatically And Obtain DNS server address automatically.
4. Restart your device.

  2. Restart your PC - Windows will install the driver automatically.

3.2. Incorrect TCP/IP settings

Sometimes the network works, but DNS servers are not responding or the gateway is assigned incorrectlyThis results in "Limited Access" even though the IP address is obtained.

How to check:

1. Open Command line (Win + R → cmd).
2. Enter in turn:

   ping 8.8.8.8
   ping ya.ru

3. If the first one ping passes, but the second one doesn't - the problem is DNS.

Solutions:

• 🔧 Reset TCP/IP settings:
  1. Launch Command prompt as administrator.
  2. Enter in turn:

     netsh int ip reset
     netsh winsock reset
     ipconfig /flushdns

  3. Restart your PC.
• 🌐 Assign DNS manually:
  1. Open Control Panel → Network and Sharing Center → Change adapter settings.
  2. Right click on Wi-Fi → Properties → IPv4.
  3. Check the box Use the following DNS server addresses.
  4. Enter:

     8.8.8.8

     (DNS from Google) or

     1.1.1.1
     
     1.0.0.1

     (DNS from Cloudflare).

3.3. Disabled IPv4 protocol

In rare cases, the protocol IPv4 This can be disabled in the adapter settings. Modern networks won't work without it.

How to check:

1. Open Control Panel → Network and Sharing Center → Change adapter settings.
2. Right click on Wi-Fi → Properties.
3. Check if there is a check mark next to it Internet Protocol version 4 (TCP/IPv4).

Solution: If there is no check mark, check it and restart your PC.

4. Problems on the provider's side

If the router distributes IP, but the indicator If the "Internet"** light isn't on, there's a problem with your internet service provider. Let's look at some common cases.

4.1. Technical work or communication failure

The most banal reason is the provider is carrying out repair work or a cable break occurred. In this case:

• 📵 The indicator light on the router is not lit Internet (or lights up red/orange).
• 📞 A call to the provider's support confirms the problem.
• 🕒 The error appeared suddenly and on all devices.

Solution: Wait for the issue to be resolved. If the connection isn't restored within 2-3 hours, call support and find out the reason.

4.2. Blocking by router MAC address

Some providers (especially Rostelecom, Beeline, local operators) link access to Router MAC addressIf you've changed your router or reset its settings, your internet may not work.

Solutions:

• 📞 Call your provider and provide the new MAC address of the router (indicated on the sticker below).
• 🔧 Clone the MAC address of the old router (if there was one):
  1. Log into the web interface of your new router.
  2. Find the section Network → MAC Clone (or Internet → MAC Cloning).
  3. Enter the MAC address of the old router.
  4. Save the settings and reboot the router.

4.3. Authorization problems (PPPoE, L2TP)

If your provider uses connection by login/password (For example, PPPoE or L2TP), the error may be due to incorrect settings.

How to check:

1. Log into your router's web interface.
2. Find the section Internet or WAN.
3. See what type of connection is indicated (Dynamic IP, PPPoE, L2TP etc.).
4. If this is PPPoE — check if the login and password are entered correctly.

Solution: Check with your ISP for the latest connection details and re-enter them. Sometimes resetting the router to factory settings and reconfiguring it can help.

5. External interference and hardware problems

If all the settings are correct, but “Limited access” remains, it’s the fault of external factors or hardware malfunctions.

5.1 Wi-Fi Channel Overload

Wi-Fi channels in apartment buildings 2.4 GHz are often overloaded. If too many networks broadcast on the same channel, the speed drops and the connection becomes unstable.

How to check:

FAQ: Frequently Asked Questions

❓ Why does "Restricted Access" only appear on one device?

If the problem is only on one device, the following is to blame:

• 🖥️ Wi-Fi adapter drivers (update or reinstall).
• ⚙️ Incorrect IP/DNS settings (reset them or assign them manually).
• 🔒 Blocked by antivirus/firewall (temporarily disable protection).
• 📱 OS crash (on Android/iOS try "Forget network").

Start by rebooting your device and router. If that doesn't help, check your drivers and network settings.

❓ How can I tell if my router or my ISP is at fault?
Take a simple test:
1. 🔌 Connect your provider's cable directly to a PC/laptop (bypassing the router).
2. 🌐 Check if there is internet.
Results:
• ✅ There is Internet → problem with the router (settings, firmware, hardware failure).
• ❌ There is no Internet → the problem is with the provider (call support).
Why did my internet connection disappear after resetting my router?

Resetting your router to factory settings erases:

• 📡 Connection settings to the provider (login/password for PPPoE, L2TP).
• 🔐 MAC address (if the provider is linked to it).
• 🌐 Wi-Fi settings (network name, password, channel).

Solution: Reconfigure your router using the details in your contract with your provider. If you don't remember the settings, call support.
