It hasn't worked.
No - just - unable to join the network "xxxxx"
Then open your internet browser and goto http://192.168.0.1 or http://192.168.1.1. Either one of the address will be your router's address and this will open router configuration window. The Login window will prompt for the router configuration username and password. The default username is “admin” and the default password XXXXX “password” (without quotes). Setup your router in there.
When you reset, your internet will be temporarily disconnected until you setup your router again. If you need any settings (like Username, Password, IP adress) you can contact your ISP. Let me know if that didn't worked. Only click Accept after it worked. Best Regards, Ashik
