2.4 GHz and 5 GHz lights not illuminated and wireless not working

The wireless suddenly went out last night.  After several reboot attempts, it is still out.  Everything is showing properly as enabled when I log in to the router.  Please don't tell me to just return to factory settings!  It took days and days and days to get this thing set up in the first place, and I need to be able to get this fixed without starting all over again from the beginning!  There must be some way to just get this thing working again.
