Hello,
[FONT=Segoe UI] [/FONT]
[FONT=Segoe UI]I have a Lumia 925 and I can't connect to facebook account over Wi-Fi (Belkin N+ router).[/FONT]
[FONT=Segoe UI]If I use only 3G I can connect without any problem, but if I enable wi-fi, I can't connect anymore.[/FONT]
[FONT=Segoe UI]This issue is only for facebook since I can connect to microsoft account, linkedin account and so on.[/FONT]
[FONT=Segoe UI]What might be a solution ?[/FONT]

[FONT=Segoe UI]Thanks[/FONT]
