I live in an area where the power can flicker on and off nearly everyday during certain seasons of the year.  When this happens the router resets to factory condition and I have to go into the http://tplinkwifi.net/ website on my hard-wired computer and set the router up again as if it's the first time it's being used.  I lose all of the previous settings and in the process lose all of the wifi devices since they are searching for the customized wifi names and passwords.  How do I stop this from happening everytime the router loses power and starts back up?
