Dedicated fan of pop star reconfigured Wi-Fi set (7)
I believe the answer is:
swiftie
'dedicated fan of pop star reconfigured wi-fi set' is the definition.
I can't judge whether this defines the answer.
'reconfigured wi-fi set' is the wordplay.
'reconfigured' indicates an anagram.
'wi'+'fi'+'set'='wifiset'
'wifiset' with letters rearranged gives 'SWIFTIE'.
Can you help me to learn more?
(Other definitions for swiftie that I've seen before include "Aussie trick" , "Half a pint" .)
