I recently switched out the router that comcast installed (netgear? maybe?) for a dlink 601 router. the install seemed to go fine with the CD set instructions that came with the router. However even though the lights are lit I can't connect my iPad or laptops using wi-fi. Am I missing something? Is there a hidden button somewhere that I need to click? I have internet connected on my desk top computer so I know the internet is connected. I'm not sure what else to do. I am a novice. Simple instructions or advice would be most appreciated. Thanks!
