This problem may occur after upgrading the Android™ OS of an Xperia™ Tablet Z or one of the Xperia Z series smartphones because of a mismatch between the MAC addresses of the two devices. The MAC address of the Xperia device has changed in connection with the update; whereas the BRAVIA® TV remembers its old MAC address.
To resolve this issue, remove the group items in the Wi-Fi® Direct settings of the Xperia device and reconnect the Xperia device to the TV.
- Using the Xperia mobile device, drag the status bar downwards and tap the Settings icon.
- Tap Wi-Fi.
- Tap the Menu button.
- Select Wi-Fi Direct.
- Tap an item under REMEMBERED GROUPS.
- Tap OK.
- Repeat for each item under REMEMBERED GROUPS.
- Reconnect with the Xperia smart phone with the TV .
