Wi fi No IP address. Keeps dropping connection

MacBook Air, 13 inch Mid 2012 running Sierra 10.12.6

My MacBook Air is suddenly constantly dropping the Wi-Fi connection. As it searches for the Wi-Fi, get an error that says "No IP address."

No Wi-Fi problems with a Dell, two iPads, two iPhones. Nothing has changed in the environment, except I think we did a regular, recommended update recently.

Got a new Router 2 months ago, but the problem did not start until 2 weeks ago.

Have confirmed that not a crowded channel, zapped PRAM, updated DCHP lease etc. Restarted Router.

I am not network savvy so some of the discussions go over my head.

This problem has essentially bricked my Mackbook and made it useless.

Help!

How to troubleshoot Wi-Fi connectivity.

Shut down the modem, router, and computer.
Wait at least one minute. Then in order:
Turn on the modem and wait until the connection is established.
Turn on the router and wait for it to connect to the modem.
Last, turn on the computer and wait until it connects with the router.

I'm embarrassed to say...that a router reboot fixed the problem. I figured I'd try again going through what I knew to do. And, sure enough, the MacBook Air is now connecting like a champ.

Thanks Kappy for your help. Sorry to bog down the forums with such an obviously easy fix. I SWEAR I tried it once before. Have no idea why it worked this time.
