Loss of Internet Connection – Devices with conflicting IP addresses may not be able to access the internet.
Frequent Disconnections – You may notice that your internet connection frequently drops and reconnects.
Error Messages – Network devices may show error messages such as “IP address conflict” or “Duplicate IP address found.”
Slow Network Performance – Even if you can connect to the network, your connection might be slower than usual.
Limited or No Connectivity – Devices affected by the IP conflict may show a "Limited or No Connectivity" status.
If you’ve experienced any of these issues while using a device with the 88E1112-C2-NNC1I000 adapter, there’s a strong chance that an IP address conflict is the root cause.
Why Does IP Address Conflict Happen?
IP address conflicts can occur for several reasons, and understanding the causes can help you troubleshoot the problem more effectively. Here are some common reasons behind IP address conflicts:
Static IP Addresses – Devices that use static IP addresses (manually assigned IPs) are more prone to conflicts, especially if two devices are configured with the same IP.
Dynamic Host Configuration Protocol (DHCP) Issues – DHCP is responsible for automatically assigning IP addresses to devices in a network. If the DHCP server fails to properly assign unique IPs or if the server is overloaded, it may inadvertently assign the same IP address to multiple devices.
Network Adapter Conflicts – Sometimes, issues with network adapters themselves, such as the 88E1112-C2-NNC1I000, may cause incorrect IP configurations.
Network Changes – Changes made to the network infrastructure, such as moving devices or modifying network settings, can trigger IP address conflicts if the network isn't updated accordingly.
Multiple DHCP Servers – In larger networks, multiple DHCP servers might be running, and if they aren’t properly coordinated, they can assign the same IP to different devices, leading to conflicts.

Step 2: Unplug your router from the power source and wait for 30 seconds.
Step 3: Plug the router back in and turn your device on again.
Step 4: Check if the conflict is resolved.
Restarting both the device and the router forces the DHCP server to reassign IP addresses, which might resolve the conflict.
2. Release and Renew Your IP Address
Another common method for fixing IP conflicts is to release your current IP address and request a new one from the DHCP server. This can be done using the Command Prompt (on Windows) or Terminal (on macOS).
For Windows:
Step 1: Open Command Prompt (press Win + R, type cmd, and press Enter).
Step 2: Type ipconfig /release and press Enter. This will release your current IP address.
Step 3: Type ipconfig /renew and press Enter. This will request a new IP address from the DHCP server.
For macOS:
Step 1: Open the Terminal application.
Step 2: Type sudo ifconfig en0 down (or en1 for wireless) to bring the network interface down.
Step 3: Type sudo ifconfig en0 up (or en1) to bring the network interface back up and obtain a new IP address.
Once this process is complete, check whether the IP address conflict is resolved.
3. Manually Assign a Static IP Address
If the problem persists, you may want to assign a static IP address to your device. By doing this, you can avoid automatic assignment errors that may lead to IP conflicts. When assigning a static IP, ensure the chosen IP address is outside the DHCP range to prevent conflicts.
Step 1: Open your network settings and navigate to the network adapter settings (for the 88E1112-C2-NNC1I000 adapter).
Step 2: Select the option to use a static IP address.
Step 3: Enter an IP address that’s outside the range provided by your DHCP server, as well as the correct subnet mask, default gateway, and DNS server settings.
Step 4: Save the changes and check the connection.
4. Check for Duplicate IPs in Your Network
In some cases, multiple devices may be using the same IP address. To address this, you should scan your network for devices with duplicate IPs and manually change their IP settings.
Step 1: Access your router’s configuration page (usually by typing 192.168.1.1 or 192.168.0.1 in your web browser).
Step 2: Log in with the router’s credentials.
Step 3: Look for the list of connected devices and check their IP addresses.
Step 4: If you find any devices with duplicate IPs, change the IP on one of them and reboot the devices.
These steps can help clear up conflicts by ensuring that each device has its own unique IP address.
