I have a Verizon FIOS Actiontec MI424WR router that I have hooked up my Deco-M4 three pack in access point mode and it is working with good Wifi coverage. I have the Wifi on the Actiontec shut off. The problem I have is that when I was using the Actiontec's built in Wifi all of my computers, both wired and Wifi connected, could see and communicate to one another. Now all of the computers on the Deco-M4 wireless can see each other and the wired computers can see each other, but the wireds can't see, or communicate with the wireless ones. Can someone give me specific instructions on how to set things up properly so that all computers on the LAN can see and communicate with one another? 

Thanks for your help.
