Wi-Fi Error: IP Conflict Detected (Android) — What It Means & How to Fix It

What Does This Error Mean?

Android shows this warning when it detects that another device on the same Wi-Fi network has the same IP address. Two devices cannot share one IP address — they will both lose reliable internet access. The fix is to force your Android phone to get a new, unique address.

Affected Models

Android 10
Android 11
Android 12
Android 13
Android 14
Samsung Galaxy
Google Pixel

Common Causes

Two devices were accidentally assigned the same IP address by the router
A device has a manually set static IP address that matches one the router later assigned to Android
The router's DHCP lease table is corrupted and it assigned a duplicate address
Android's randomized MAC address feature caused the router to assign a duplicate IP
The router was restarted and re-assigned the same address to a different device

How to Fix It

Toggle Wi-Fi off and back on. Go to Settings > Wi-Fi and turn it off. Wait 10 seconds and turn it back on. Android will request a new IP address when reconnecting.

Simply reconnecting often gets Android a different IP address that does not conflict.
Restart your router. Unplug it for 30 seconds and plug it back in. This clears all DHCP lease records and reassigns addresses fresh to all devices.

Restarting the router forces every device to request a new address — resolving the conflict completely.
Forget and rejoin the Wi-Fi network on your Android phone. In Settings > Wi-Fi, tap the network, select Forget, then reconnect with the password.

This gives Android a clean slate for negotiating a new IP address.
Disable MAC address randomization on your Android phone for this specific network. In Settings > Wi-Fi > tap the network > Privacy > use Device MAC. Reconnect.

Random MAC addresses can confuse router DHCP tables and lead to duplicate assignments.
Temporarily set a static IP to bypass DHCP. In Wi-Fi network settings > Modify > Advanced > IP settings: Static. Use 192.168.1.200 and gateway 192.168.1.1 — a high address unlikely to conflict.

Switch back to DHCP after fixing the router to avoid future static IP conflicts.

When to Call a Professional

IP conflict detected is almost always fixable without professional help. If it keeps happening repeatedly, log into your router admin page and expand the DHCP range, or check for devices using static IP addresses that overlap. If you cannot access the router settings, your ISP can assist you remotely.

Frequently Asked Questions

What is MAC address randomization and why does it cause IP conflicts?

Modern Android phones use a random MAC address when connecting to each Wi-Fi network for privacy. The problem is that routers track devices by MAC address to assign consistent IP addresses. When the MAC address changes, the router may hand out an address it already gave to a different device. Disabling randomization for your home network gives your phone a consistent identity.

Which device is causing the conflict — my phone or another device?

It is impossible to tell from the Android warning alone. The conflict is between your phone and at least one other device. Restarting the router forces all devices to re-request addresses, which usually resolves it without needing to identify the culprit.

Can I stop IP conflicts from happening permanently?

Yes. The most reliable solution is to make sure all devices use DHCP (automatic IP assignment) and none use manual static IPs that overlap. For devices that need a fixed address (like printers), configure the router to always give them the same address via DHCP reservation — a feature on most routers.
