Windows 11 Pro PC Connects to Local Private Network but No Internet Connection

Introduction

In this article, we will explore the steps to connect a Windows 11 Pro PC to a local private network (LAN) even when there is no internet connection available. We will also cover the key concepts related to this topic, including how to manually configure IP addresses and use DHCP to generate IPv4 addresses.

Understanding IP Addresses

An IP address (Internet Protocol address) is a numerical label assigned to each device participating in a computer network that uses the Internet Protocol for communication. There are two types of IP addresses, IPv4 and IPv6, and each device that connects to the internet must have a unique IP address.

 IPv4 Address: 192.168.1.1
 IPv6 Address: 2001:0db8:85a3:0000:0000:8a2e:0370:7334
 

Manually Configuring IP Addresses

Sometimes, when trying to connect to a local private network, the PC may not be able to automatically configure the IP address using DHCP (Dynamic Host Configuration Protocol). In these cases, it's necessary to manually configure the IP address. To do this, follow these steps:

1. Right-click on the network icon in the taskbar.
2. Click on "Open Network & Internet Settings."
3. Click on "Change adapter options."
4. Right-click on the network adapter and select "Properties."
5. Double-click on "Internet Protocol Version 4 (TCP/IPv4)."
6. Select "Use the following IP address" and enter the IP address, subnet mask, and default gateway.

Using DHCP to Generate IPv4 Addresses

DHCP is a protocol used on IP networks to dynamically assign IP addresses to devices that are connected to the network. To use DHCP to generate an IPv4 address, follow these steps:

1. Right-click on the network icon in the taskbar.
2. Click on "Open Network & Internet Settings."
3. Click on "Change adapter options."
4. Right-click on the network adapter and select "Properties."
5. Double-click on "Internet Protocol Version 4 (TCP/IPv4)."
6. Select "Obtain an IP address automatically" and click "OK."

In this article, we have covered the steps to connect a Windows 11 Pro PC to a local private network with no internet connection. We have also explored the key concepts related to this topic, including manually configuring IP addresses and using DHCP to generate IPv4 addresses. It's important to note that having a unique IP address is crucial for devices to communicate with each other on a network.
