Having Trouble Connecting Your Aroma Retail Scent Machine to a TP-Link Mesh Network? Here’s What You Need to Know
If you landed on this page, it probably means you have been having issues connecting your Aroma Retail Scent Machine to your TP-Link Mesh Network. Rebooting, re-pairing and moving the machine closer to the router and your Aroma Retail Scent Machine is still refusing to connect. You’re not alone. Many users hit the same roadblock when pairing a scent machine with a TP-Link mesh Wi-Fi system.
The good news: it’s not the machine, and it’s not your Wi-Fi quality. It’s simply how mesh networks handle smart home devices.
Why Your Aroma Retail Device Won’t Connect on Standard Mesh Wi-Fi
Mesh networks (like TP-Link Deco X20, XE75, M5, etc.) automatically switch devices between 2.4 GHz and 5 GHz to maintain “optimal” routing. But some smart devices, like the Aroma Retail Scent Machine, don’t like that automatic band shifting.
So, the device starts pairing…
then the mesh system tries to hand it off…
and..Nothing…connection fails or drops.
Common Symptoms You Might Have Already Seen:
- “Connection failed. Try again.”
- “Password Incorrect. Try again.”
- Aroma Retail app finds Wi-Fi but can’t finish setup
- You can see the SSID in your settings, but device setup never completes
This problem isn’t unique to Aroma Retail, it can happen with doorbells, plugs, smart switches, and other IOT devices on mesh systems every day.
The Fix: Create a Dedicated IoT Subnetwork for Your Scent Machine
TP-Link finally answered this universal smart-device headache by adding IoT Network Mode.
Instead of letting both 5 GHz and 2.4 GHz battle it out, the IoT subnetwork broadcasts a dedicated Wi-Fi channel that stays locked to 2.4 GHz, exactly what the scent machine needs.
What This Solves Instantly:
- Prevents mesh from shifting the device between bands
- Create a smoother connection experience
- Avoids security mismatches (WPA3 vs WPA2)
- Reduces congestion from phones, laptops, streaming devices
- Keeps the Aroma Retail scent machine connected 24/7
How to Set Up the IoT Subnetwork (What You Actually Came Here For)
Steps in TP-Link Deco App
- Open the Deco App
- Tap the More menu
- Select IoT Network
- Toggle Enable IoT Network
- Set:
- Network Name: Aroma-IoT (or anything you like)
- Password: unique but simple
- Frequency: 2.4 GHz only
- Security: WPA/WPA2
- Save and wait for the network to broadcast
Important: It's important that you choose WPA2 for the security protocol. Some IoT devices simply don’t speak WPA3 yet.
Now Connect Your Aroma Retail Scent Machine
- Ensure your Aroma Retail Scent Machine is on and ready to pair
- On your phone, join the new IoT SSID (Aroma-IoT).
- Open the Aroma Retail device app and complete setup.
- Once paired, switch your phone back to your main Wi-Fi—your machine stays on IoT.
No re-pairing, no drops, no random disconnects when the mesh decides to “optimize.” Here is a link from TP -Link if you want to hear straight from the source on how to set up your IOT Network: https://www.tp-link.com/us/support/faq/4420/.
