My Netgear Wi-Fi won't work on my iphone or kindle fire?

My Wi-Fi was working perfectly fine but then just stopped working. Now my iphine and kindle fire can't find our Wi-Fi. Even my laptop says no networks found. I'm still able to get online through our home computer which is ran by hughes net but thats it. On the netgear modem the lights for power, internet and number two are all on so i have no idea what's wrong.

All you need to do it to change your Wi-Fi broadcasting channel. Open up your router's setup by entering the default gateway IP, enter username password if prompted ->go to Wi-Fi or Wireless Lan setting and make sure that broadcasting is b/g/n mixed mode, then check what broadcasting channel is selected starting from 1 to 11/13, in case of extreme start or end make in middle like 6 or 7 and in case of any middle number like 6 to 8 make it either 10 or 3.By changing the broadcasting channel shall hopefully stop any interference with other frequencies.
