Network Adapter/Router assigns bogus IP address

I decided to upgrade my wireless router to a new AC router (Netgear). That was a mistake. I had nothing but problems with setup and connecting devices.

So I decided to go back to the old router (Linksys) and I figured that everything would just re-connect as it had before. However, one of the computers that was directly wired into the router (not wireless) would not connect to the internet.

PRIOR to trying the new router the IP address of the computer was 192.168.1.106 After trying the new router and then going back to the old Linksys router, I noticed that the automatically assigned IP address of the computer was 192.168.2.3 Again, this is with the OLD Linksys router, even though the previous connection had been 192.168.1.106

If I go into adapter properties and change the IvP4 to a static IP address, and change it to the former 192.168.1.106 then the wired connection will connect just like it used to to the Linksys router. But as soon as I try to change the adapter properties to automatically assing an IP it goes right back to 192.168.2.3

I have absolutely no idea where the 192.168.2.3 address comes from, except that perhaps it had something to do with the new Netgear router that I removed.
