LAN printer in WIFI network

Hi

I have a problem getting a network printer ( Ricoh MP-171) and internet access to work at the same time.

Here is my situation :

Two PC's both running Windows 8.1 are connected to office WIFI, works fine !

Now I am trying to get the network printer to work, It cannot connect to the WIFI network ( and the rest of the office should not be able to print to it)
so I placed a Router, set the IP range to that of the printer and connected the 3 devices to it using UTP cables.

Now both PC can print , but internet access no longer works , apparently windows is trying to connect to the internet over the wired connection !


In advanced settings menu ( Network connections / change adapter settings ) I swicthed 'provider order' but that did nothing
I also tried bridging both networks ..


when I disable the LAN port , internet works ( but obviously I cannot print )

network details :
Wifi default gateway : 192.168.11.1 ( I am not allowed to change any setting here )
Lan default gateway : 192.168.1.1
Printer IP : 192.168.1.252 ( http://192.168.1.252 In a browser I can see the RICOH page , I could not find were to change the IP address but that is a different problem )


what am I doing wrong ? Is using a router the correct choise .. is there an easier solution. maybe getting the router to pick up the wifi ?


thanks for your help
