We have received couple similar report, but have not found the root cause.
According to one of the reporters, when he reset his router, everything works fine. So we suspect some wireless config has something to do with the issue.
Any chance you can reset your router and try again? If it works after reset router, could please restore your settings one by one and help to narrow down the root cause?
BTW, could you change your router console page to English and send the screen capture again?
Thanks in advance!
