Normally, when hit by lightning, a lot of devices end up getting damaged. If so, it's possible that it's not only your router, but your modem as well (you're lucky only your router was damaged). Anyway, a few things to check:
1. If you connect your computer directly to the modem, do you have a connection? If so, the problem could be w/ the router.
2. Does your router actually still turn on? In my experience w/ lightning, it killed the router. Wouldn't even turn on anymore. I suggest getting a new router, it's probably more cost-effective that having it repaired.
3. Are you still able to connect to your router? Can you access it's homepage (it's usually:
http://192.168.1.1)?
Also, what's your broadband connection? PLDT? Globe? Router model?
