Yes there is a difference. A wireless access point acts as your wireless agent on a network for wireless user to access the network. A wireless bridge connects a wired device, such as a stoker, to the wireless network. If you have a wireless router, you do not need an access point, it's built in, That's not to say you can't have both, but that's another issue. Here's the twist, some wireless access point can act as wireless bridges, such as DLink 2100AP. I doubt that WG602 will act as a wireless bridge. (these are also called wireless gaming adapters)
