如果 WiFi 网络旁边有“连接受限”^{(‘limited connectivity’)}标志，则表示您已连接到网络但无法访问互联网。此问题的主要原因是DHCP服务器没有响应。当DHCP服务器没有响应时，计算机会自动为自己分配一个 IP 地址，因为DHCP服务器无法分配 IP 地址。因此出现“有限或无连接”错误。^{( ‘Limited or No connectivity’ error.)}

Fix Limited Access or No Connectivity WiFi on Windows 10

If a WiFi network has the ‘limited connectivity’ sign next to it, it means that you’re connected to the network but do not have access to the internet. The main reason for this issue is that the DHCP server is not responding. And when the DHCP server doesn’t respond the computer automatically assigns an IP address to itself because the DHCP server was unable to assign the IP address. Hence the ‘Limited or No connectivity’ error.

Fix limited access or no connectivity WiFi issues

Method 1: Run Network troubleshooter

1. Right-click on the network icon at the taskbar and click on Troubleshoot problems.

2. The Network Diagnostics window will open. Follow the on-screen instructions to run the Troubleshooter.

Method 2: Reset TCP/IP

1. Right-click on the Windows button and select “Command Prompt(Admin).”

2. Type the following command: netsh int ip reset c:\resetlog.txt

3. If you don’t want to specify the directory path then use this command: netsh int ip reset resetlog.txt

4. Reboot the PC.

Method 3: Change Bitdefender firewall settings (Or your Antivirus Firewall)

1. Open Settings of Bitdefender Internet Security and choose Firewall.

2. Click on the “Advanced Settings” button.

3. Make sure that “Enable Internet Connection Sharing” is checked.

NOTE: If you don’t have the above setting then disable “Block Internet Connection Sharing” instead of above.

4. Click the OK button to save changes.

5. And if it doesn’t work try disabling your Antivirus Firewall and enabling Windows Firewall.
