Network not found

when power is supplied to the WiFi module the blue LED blinks constantly. i am able to get to the and the network setup page. from this page it will say "searching for networks" then "no network found" or it will give me a drop down list of available networks, and when i select one it says "failed - network not found". sometimes it will let me select a network and input password, then spend some time connecting and result in "Failed - network not found)

i have used the flash tool 3.0 to re flash 2.2.5 with the same results. 

 same issue with a board what was working for a week then suddenly poof!  I am going to contact support because i think its the nodemcu wifi chip gone to gumbyland
