N7 (after 4,2 update) reboot after connect to wifi

[wyl51]

Hi all,

another question from me.

i got my n7 updated with the rebooting issue, which i sorta fixed after hard reset.
i was very happy with it until i bought it to my office.

once it connected to the WIFI in my office, it reboot.:'(

anyone could teach me how to fix?

Thanks!
