Hi TPG - I have recently changed my wi-fi password from the default to a new one which is easier to remember. Since then, my macbook pro failed to connect to the wi-fi. The network is detected but it keeps saying it has have no IP address. I tried keyed in manually but still not working. All my other apple devices such as tablets and mobile phones are well connected to the same wi-fi. Please advise if there is something wrong with my macbook network setting. Thanks!
Welcome to the Community @queenykeithchan.
Have you tried to forget the WiFi network and reconnect using the new password?
If not, try it first.
If you are still not able to get an IP or internet using the WiFi network, shoot me a PM with your TPG username or customer ID number to assist you further.
