Nighthawk MR1100 Something Unusual On Battery Display

The display shows NETGEAR, then the light in the top right hand corner start to blinking yellow, then blue, then yellow, then blue, then yellow then it quits.  Where it first showed NETGEAR now it shows a battery with what looks like a little lightening bolt in front of it and below there appears to be a little clock.  Everything has worked well up to now.  Then this started happening.  I tried taking the battery out for 60 seconds and then putting it back in.  That did not help.  Please help me with this.  I need the Wi-Fi to work.  Thank you.
