Router Sign-on Issues

[tclatt]

Help - I had lightning strike close to our house and in essence knock our router out (lights were all out).  I unplugged it and it started lighting back up and working and worked for approximately 12 hours.  It is now lighting up, but does not seem to be working.  I try to connect to it and it requests the password and when I put it in it says it is the wrong password.  It is all lit up like it would be working, but it isn't.  I wasn't sure if there was something I could do to reset it or if something did happen to it that took a litle time to develop.  Any ideas are appreciated.  Thanks

I would start with a factory reset and then reinstal the firmare. 

Push and hold reset for 7-15 seconds while its powered on. 

then reinstall the firmware to it. A reset only clears out settings. By reinstalling the firmware, you potentially overwrite any corrupt firmware. 

Lightening does a great job of wrecking things. I'd start with those options if you can
