Deco support both 2.4G and 5G at the same time. Whether it uses 2.4G or 5G depends on your devices. If your skybell can only support 2.4G, it can find deco's 2.4G as well.
It seems the skybell can find the deco but can't connect to it. You may change the password of deco or ask help from skybell's support.

I see. OK, I will reach out to skybell. Appreciate the response!

:DMy pleasure. Any update will be welcomed.

I have same issue now. Anyone fixed this issue. Skybell support saying Att router must put in bridge mode to connect this. I don't know how to do that? If anyone has clue please share with me.

step 2 (advance setting)worked for me

Step 1:
1. Press your SkyBell button in and hold it for about a minute. The LED will flash (rapid green>red and green>blue>yellow).
2. Once you see the LED flash yellow, please release the SkyBell button.
3. Within a minute, your SkyBell will be flashing red and green.


To Re-Sync the Device once it is flashing red/green:
Note: Please stand near the SkyBell during the syncing process
1. Open the SkyBell HD app and press "Add a SkyBell"
2. Press the green arrow at the bottom 2 times
3. Press the box with an arrow in it and turn "Airplane Mode" on
4. Press the back button
5. Press the box with an arrow in it and turn Wi-Fi on
6. Select the network "SkybellHD_XXXXXXX"
7. Press the back button
8. Press the green arrow at the bottom
9. Select your home Wi-Fi network
10. Press the green arrow at the bottom
11. Enter your home Wi-Fi network password
12. Press the green arrow at the bottom.
13. The app will remind you to turn off "Airplane Mode" but do NOT turn it off until the sync is complete.
14. Your SkyBell should begin changing colors; it should flash Orange, then flash Green/Blue, then finally turn solid Green
15. When the SkyBell is solid green, your sync is complete and you can turn off "Airplane Mode"

Step 2:
******************** If not working above *************************
Once it is flashing red and green, select 'Add a new SkyBell' in your app and follow the on-screen instructions to re-sync
your device until after you have selected your network. When asked to input your password, please select the "Advanced" at the top.


When syncing, you will need to use the advanced options within the SkyBell Application and enter the information below.


It will ask for the following:
Password: This will be your WiFi password
IP Address: (see gateway first) Use the first three numbers from your default gateway and 201 for your 4th number (e.g. if your gateway is 192.168.1.x, use 192.168.1.201)
Subnet Mask: 255.255.255.0
Gateway: Use the number that follows "Default Gateway" on the sticker on your router/extender that you are using to connect the device (e.g. 192.168.1.1)

I hope this is help!
