DH says: define "can't get it to work" the tv being internet ready is irrelevant. If it detects the wireless network, the setup is relatively straight forward.
"if the tv is connected via wireless and working fine, that could be why she mentions the tv."
so, the steps are, 'does it detect the wireless network?'
'if yes, then does it provide a signal strength, how strong is it?'
'if no, then what sort of network setup is it, WPA/WEP/WPA-2'
