new router sent to me after first router seemed defective, same issue with new router cannot name wifi or change password

White light blinking on router fresh out of the box.  Couldn't establish a connection 3 times after saying "connecting will take 3 minutes" unplugged router set a timer for 1 minute replugged in. White light blinking. I get through the process until it asks me to name the wifi and create a password. Tried 3 times it says "there was a problem" I cannot get past this step and cannot set up my wifi and it's taking me weeks to get set up as a result and I'm tired. I had the same problem with my last router but the last router also didn't display the power light as being on even though the other lights would blink on.
