Did you check if the router's WiFi channel is one your Samsung can use?
Is the router within 20 feet for the first setup?
Why does the channel matter? Read http://forums.cnet.com/7723-13973_102-560420/wifi-disconnects-from-time-to-time-galaxy-tab-7-plus/?tag=contentBody;threadListing
You bring up a good point. Should these products have more integration and not rely on folk learning about networks and WiFi channels?
My p3600 identifies a wireless connection that I do not have and I cannot figure out how to get it to see the wireless router signal I DO have. The wireless signal comes from a Verizon FIOS router that has a 16 character wpa2 key and an 8 character wps pin. I have never gotten the player to hook up to any wireless system so detailed steps would help. Thanks!
