Trying to set up this travel router, TL-WR 1502X. When appearing on my new Apple laptop screen, and the unit set on hot spot,I click on it then immediately it goes to a screen asking to change my administrator password, then the unit led goes to red. 
Ultimately, I went ahead and worked through the set up with the led light red on and succeeded.The light turned back to blue.  But why did the led system light turn red leading me to believe something was wrong although the login set was unsuccessful. I wasted hours of time researching to get information about the red operational light significances. 
Has anyone else had this problem?  If so I would appreciate it if you could enlighten me.
