IP and subnet basics
How to fix IP address conflict
A practical guide for people searching "How to fix IP address conflict". It explains what to check first, what not to reset too early, and which 192.168 pages or tools help confirm the result.
Quick answer
Start with the same-network check, confirm the default gateway, test the exact URL, then change one setting at a time. Do not factory reset until you know the password, ISP app, and backup options.
Why people share it
This page works as a clean support answer: it separates symptoms, causes, tests and next actions so forum helpers can link one URL instead of rewriting the same router checklist.
When this guide applies
- The fastest fix depends on whether IP address conflict is a wrong address, a browser block, a Wi-Fi isolation rule, a password problem, or a router service that is no longer listening.
- Check the subnet: a /24 home network usually keeps devices in the same 192.168.x range.
- Compare the address with the operating system default gateway.

Detailed steps
Identify the exact symptom
The fastest fix depends on whether IP address conflict is a wrong address, a browser block, a Wi-Fi isolation rule, a password problem, or a router service that is no longer listening.
- Check the subnet: a /24 home network usually keeps devices in the same 192.168.x range.
- Compare the address with the operating system default gateway.
- Test from another phone or laptop before changing router settings.
Run the checks in a safe order
Use the checks below from a device connected to the local network. Keep notes of the IP, browser error, Wi-Fi network name, and whether another device behaves differently.
- Compare the address with the operating system default gateway.
- Test from another phone or laptop before changing router settings.
- Back up settings or screenshots before changing passwords, DNS, DHCP or NAT.
Decide the next action
If a quick check succeeds, use it to narrow the cause. If every check fails, reboot first, then consult the label, ISP app, or manual before attempting a reset.
- Assuming every router uses 192.168.1.1.
- Factory resetting before saving ISP and Wi-Fi settings.
- Leaving mobile data or VPN enabled, which sends traffic outside the LAN.
Make the result shareable
When asking for help, include the private IP, gateway, browser error, router brand, connection type, and what changed recently. That prevents generic answers and speeds up support.
