Internet router unable to assign static IP
4.5
The router fails to assign a specific IP address to a device.
Symptoms
- IP conflict error
- Device gets a random IP
- Static IP settings don't save
Possible Causes
- IP outside of DHCP range
- MAC address mismatch
- Firmware bug
Step-by-Step Fix
1
Check DHCP Range
Ensure the static IP is within the router's subnet but outside the DHCP pool.
2
Verify MAC Address
Double-check that you entered the correct MAC address for the device.
3
Reboot Router
Forces the DHCP table to refresh.
When to See a Technician
It is often better to set the static IP on the device itself rather than through the router reservation.
