Help: Apple product no longer have access to web (internet)...

but everythin else does...

This is a very stange bug, since about a week ago, I added a new network card 10gb (instead of 1GB) to upgrade my network. Then all apple product stoped have access to internet via my AP (unify UAPHD pro). Stranger still, all PC do have access to the web via the same AP point. And apple products will no longer have access via cable connection to the web either unless I manually change the router IP to the router main IP (and DNS). I've tried to do the same on the ones using WiFi to no avail...

I can ping and see the apple products (Ipad, Iphones, Apple TV).

Classic case of firmware version I thought... I've upgraded everything to the latest... no connections
Classic case of software version I thought... I've uploaded the latest on all machine... no connections
Classic case of incompatible network card... I've revert back to the old one... no connections
Classic case of corrupted wifi AP point... I've reset them to initial... no connections...latest firmware... no connection... change company AP point...no connection
Classic case of corrupted clearos .... I've created on a new drive with the brand new out of the box Clearos install... No connection...

I've runout of classic cases... and idear LOL

Anyone have a sugestion?
