Extend wireless over ethernet?
I have an Airport wireless/ethernet network in my house, and I have an AP Express in a remote barn on my property. There is an ethernet cable running from house to barn, but any wireless signals are weak. The ethernet is connected to the Express WAN port. Utlimately, there will be IP cameras in the barn, and I need the video to appear back on the house network. The cameras will mostly be wireless, perhaps some wired.
Can I set up the Express in the barn to extend my house wireless networkk via the ethernet cable? I am having trouble configuring this - the setup utility just gives "unexpeced error" when trying to connect to the (unconfigured) Express. Am supposed to have two wireless networks with different names, or can both buildings be under a single network? I read somewhere that I have to turn the "bridge mode" off, but I'm not sure what that means or if it's true.
Thanks for any advice
