Some Devices Picking Up The Wrong IPs From DHCP Server

  • 2

I have a network of PC and laptops connected to a router and out to the internet.
I have the DHCP server in the router set to give out addresses from 192.168.1.100 to 200.

Up until yesterday everything worked just fine.

Today I’ve found several computers that could not connect out to the internet. I looked at the IPs and they were not in the range they should have been. Their IPs were 192.168.254.xxx and off course could not connect as this is a different network than the router altogether.

I made their IPs fixed in the right range (192.168.1.xxx) and they work fine.

Can’t figure out why they are not picking the right IP????

Any ideas?

    1. Is this a wired or wireless network?
      The only way a computer can pick up the wrong IP address is if some other computer or device is providing DHCP services. Such as another wireless router that is in range.
