Trouble connecting my wd tv live plus to optimum wifi

any suggestions? im currently connected to some neighboring wifi but id like to connect to my own optimum wifi…i think it says something about the dns but im not sure, anybody have a similar problem? 

itll say connection successful or whatever but then when i try to use internet media like netflix it won’t connect but when i connect to the other wifi (dlink), i have no problems
