I have Actiontec model GT784WNV router/modem is it wireless?
It doesn't have a visible antenna and I cant seem to set it up for wireless
A lot of newer routers don't come with visible antennas, which suck for flexibility. They are all internal and/or on chip. That ActionTec is certified from what I see as a Wireless N (single band) router so it should be able to do wireless. How/where are you attempting to set up the wireless?
