Hi will1,
Welcome to Sony Community!
We apologize for this inconvenience. Did you update wireless driver after you reinstall it?
Try the steps below:
- Boot to Safe Mode and verify if the issue persist. A successful network connection in safe mode indicates the interference of firewall or Internet security software.
- Turn off the router and broadband modem and then turn them back on to reset the units. It may be necessary to update the firmware version on the router. Check the router manufacturer's Web site for update instructions.
We kindly recommend visiting our Sony Global Web site for information on contacting the Sony Support Center in your region at http://www.sony.net/SonyInfo/Support/.
Regards,
Jen
