I currently have a desktop computer running windows 7 and a lapptop running Mac OS X 10.5.8. My wifi router is Tenda 311R b/g/n 150 Mb/s. Can you show me the way to setup a wireless lan? I tried to set the shared folder on windows7 but, how to say it .... both my desktop and lapptop (running OS X) cannot see each other. I can only access to shared folder when my lapptop also running W7, and the speed connection is very low (only about 5 Mb/s ) Thank you for your helps.
