IP address conflicts that Don't really exist!

I'm using a Mac Pro running Mavericks. Connecting to the internet through my NetGear N900. I've been having the error message "Another device on the network is using your computer's IP address (192.168.1.4) The issue is that I have set the router to give the computer the address 192.168.1.3 and have set the computer to use the same ip as a static address. I also checked the connected devices in the Netgear genie and there are no computers with the ip of 192.168.1.4 Why is my computer doing this? I can still get on the internet. But it has been very slow lately. On all my connected devices.

Anyone with information please let me know.

Thanks

Maybe you use both Ethernet and WiFi to connect with the same IP to router?
Use an IP like 192.168.1.101 and test the speeds on both WiFi and/or Ethernet.

I hope this helps.

Unfortunately that's not the case. I do have an ethernet cable plugged into that computer right now, but this problem was happening before I did that. Besides the IP on the ethernet connection is 192.168.1.5.

The issue is that I have set the router to give the computer the address 192.168.1.3 and have set the computer to use the same ip as a static address.

So you are using DHCP reservations on the router to assign that IP to the Macs MAC address? If that is the case, you do not need to assign the Mac a find IP address. Just leave the Mac set to use DHCP and the router will assign that same IP every time effectively giving you a fixed IP on the local network.

You don't want to have DHCP reservations on the router and a fixed IP on the Mac both.
