There are a few situations where you can get an IP address conflict:

-One or more of your devices is set with a Static IP address that is within the range being given out by your router - so when the router assigns that IP to another device, the two conflict

-You have more than one device on the network running DHCP, and their IP ranges overlap

-Your router is broken and is giving out the same IP to multiple devices (very,very unlikely)

This used to happen with our stupid old router.  For example: Basically, one PC would be given a certain IP, then another one would be started up and assigned another IP, etc. and then the first one would go to sleep.  The router would then see that number as free, and would give it out to another computer.  Then the first one would wake up again and BAM IP conflict.  I think disconnecting from the router (just click the wifi icon and disconnect) and then reconnecting should fix it.  Or reboot one or both machines... or, you know, upgrade the router to a smarter one

Depending on your router, you can do MAC address reservation. When you have a device connect to the network, you use the MAC address to reserve a specific IP address for each device. You can still keep DHCP for unassigned devices; the ones that are reserved though will only be used for that specific MAC address you assigned.

This is actually the preferred solution as long as your DHCP server is reliable. There are only certain services, like a DHCP, VPN, or routing/NAT device that truly need their IPs set statically on the device itself. Everything else is better done as a DHCP reservation.
