MK808B + Finless 1.7 Wi-Fi Problem

[mishtag]

My friend has MK808B flashed with Finless 1.7, and few days ago he had power outage, and when the power was restored, the MK808B doesn't connect with Wi-Fi, it keeps trying to connect and obtaining the IP adress but not connecting, so I fist rebooted the router and it didn't work, then I tried to remove the network connection from the list (forget it) and reconnect and didn't work, and finally and re-flashed it again with finless 1.7 and still not working, so now, before I call the internet service provider and maybe reset the router, is there any option in in the MK808B it might fix the problem?

Did unplug and replug the router? That's the first thing I would do.

EDIT: I see that now you did.
