Amazon Kindle Paperwhite Can't Detect Your WiFi Network

My Kindle Paperwhite couldn't identify my router's SSID. I'm using TP Link router that has wireless N capability. The Kindle Paperwhite won't connect to a 5Ghz N band so I Enabled the dual band feature on the router and used the 2.4 Ghz band in wireless b/g mode only! Rebooted the router and it worked!
