thank you for ur advice......is there any other reason to look for add on wifi cards besides cost??
at the moment i am currently thinking of asus z77 with "wifi go" feature......
is it enough to have any wifi capability for pc to stream hd media/files to tablets/tv??
I currently have a wifi card and I cannot get it iPad with m iPad rather I use a Internet modem router for sharing files it doesnot use Internet even when Internet is connected.
Also te range of the external router is generally much better than internal cards.
