Keurig K-Supreme SMART Won't Connect to App? 5 Fixes

What the App Connection Adds on the K-Supreme SMART

The K-Supreme SMART brews without the app. Its buttons, sizes, five strengths and six temperatures all work from the brewer. What the Keurig app adds is BrewID recommendations, remote brewing and scheduling, Favorites, voice control and Smart Auto-Delivery. So when it won't connect, you've lost the extras, not your coffee.

Keurig's Use & Care Guide gives one connection procedure, started from the app and finished on the brewer. Keurig's own FAQ for the K-Supreme Plus SMART adds one requirement: it "only supports a 2.4GHz Wi-Fi network. It will not work with a 5 GHz Wi-Fi network." The plain K-Supreme SMART's guide doesn't name a band. If your router mixes both bands under one name, the 2.4 GHz requirement is the first thing to check.

Try This First

• Have your home Wi-Fi password ready. The guide asks for it at the start.
• Check your network is 2.4 GHz. On a dual-band router, the 2.4 GHz network is usually the one without "5G" in its name.
• Update the app. Keurig's FAQ for the Plus SMART lists iOS 11 or Android 6 as minimums.
• Stand near the brewer. You'll scan the QR code on its back and press its buttons during setup.

Fix 1: Connect on a 2.4 GHz Network

Keurig's FAQ is clear for the Plus SMART: 2.4 GHz only. A brewer told to join a 5 GHz network can't finish connecting.

1. Find your router's 2.4 GHz network name. It's on the router label or in its app.
2. If the router shows only one name for both bands, check its settings for a separate 2.4 GHz network.
3. Choose the 2.4 GHz network when the Keurig app asks for your Wi-Fi.
4. Enter the password carefully. It's case-sensitive.

Fix 2: Run the Guide's Connection Steps in Order

The guide's sequence goes back and forth between app and brewer, and skipping a step stops it.

1. App: download the Keurig app and select Get Connected to create an account. Already have the app? Go to Settings → Connect a Brewer → Get Started.
2. Scan the QR code on the back of the brewer.
3. Brewer: press both arrows at the same time to open Settings.
4. Press the right arrow to reach the Wi-Fi settings.
5. Press the K button, then the right arrow to Connect.
6. App: tap LINK and follow the in-app instructions.
7. The brewer shows SUCCESS! when it's connected.

Keurig also has a How To Connect video at keurig.com/connect.

Fix 3: Change the Wi-Fi Settings on the Brewer

New router, or changed your password? The brewer keeps the old details until you change them. Its Settings menu has a Wi-Fi item to "Connect to your Wi-Fi network, modify your password, and change the Wi-Fi settings."

1. With the brewer plugged in and on, press both arrows together.
2. Scroll with the right arrow to Wi-Fi.
3. Choose to connect again, modify the password, or change settings, and follow the screen.
4. Finish in the app with LINK, as in Fix 2.

Fix 4: Check BrewID Separately

A connected brewer can still miss BrewID recommendations. The guide's row "Recommended Brew Settings Are Not Provided or a Keurig K-Cup Pod Is Not Recognized" lists these checks:

1. Make sure the brewer is connected to Wi-Fi. BrewID needs it.
2. Use a genuine Keurig K-Cup pod, with the Keurig logo on the lid.
3. Use an unpunctured pod. "If a Keurig pod's lid is already punctured, it may not be recognized."
4. If Keurig pods still aren't recognized, contact Customer Service.

Fix 5: Factory Reset, Then Connect From Scratch

The SMART's Settings menu has a Factory Reset that "resets to the original manufactured state". The guide doesn't offer it as a fix for any fault. It's the last step before calling Keurig, and it wipes your settings and Favorites from the brewer.

1. Press both arrows together to open Settings.
2. Scroll with the right arrow to Factory Reset and confirm.
3. Set the brewer up again, then run the connection steps in Fix 2.

Time: 15 minutes
Cost: Free
Difficulty: Easy

When to Contact Keurig

If the brewer still won't connect on a 2.4 GHz network after these steps, the Settings menu has a Support item with contact details. You can also call Keurig Customer Service at 1-866-901-BREW (2739). The brewer is covered by a limited one-year warranty in the US and Canada.

Prevention

• Keep the 2.4 GHz network name and password unchanged, or update the brewer (Fix 3) when they change.
• Keep the app updated.
• Check Settings → Brewer Information to see the brewer's installed software version.

FAQ

Does the K-Supreme SMART work without the app?

Yes. Brewing, strength, temperature and sizes all work from the brewer. The app adds BrewID, remote brewing, scheduling, Favorites and voice control.

Can a Keurig SMART brewer use 5 GHz Wi-Fi?

Keurig's FAQ for the K-Supreme Plus SMART says no: 2.4 GHz only. The K-Supreme SMART guide doesn't name a band, so connect it to 2.4 GHz as well.

How do I connect if I skipped setup out of the box?

In the app, go to Settings → Connect a Brewer → Get Started, scan the QR code on the back of the brewer, then open Wi-Fi in the brewer's Settings (both arrows) and press K then the right arrow.

How do I set up Alexa or Google Home?

In the Keurig app: Settings → My Account → Voice Control, then follow the prompts.
