- Incorrect Wifi password: Incorrect Wi-Fi password will cause dbell to go offline
- Wi-Fi signal drops: dbell will go offline if Wi-Fi signal strength drops to -60dBm to -100dBm.
- In-sufficient Power: dbell will go offline when supplied power is insufficient. Noticeable Symptoms, dbell restarts after few minutes, makes a static or hum noise.
- Corrupted microSD card: Corrupted SD card will cause dbell to go into offline state
- New Router: Router has been changed but dbell is not synced with the new router
Suggested corrective action:
1. Incorrect Wifi password: Incorrect Wi-Fi password is number one reason for dbell to go offline.
- Connect dbell to your router by a Data cable for a short time
- Power-up dbell
- Open your dbell app
- Wait few seconds for the dbell to be online - Blue Dot before the dbell name means dbell is Online. If you see yellow Dot or red Dot dbell is not Online, no settings will work.
- Go to >> Settings - 4 square icon
- Click Manage Wireless Networks
- From the list of Wifi networks - Select your Wifi SSID name
- Enter Wifi password
- Click "Connect to WiFi"
- Wait for dbell to restart
- Once dbell is online(Blue Dot) disconnect Data cable. dbell will go disconnect then go Online.
- If your Wifi password was incorrect - dbell will not work - retry the steps from start.
2. Wi-Fi signal drops: dbell will go offline if Wi-Fi signal strength drops to -60dBm to -100dBm.
- Wi-Fi signal strength is weak(-60dBm to -100dBm). Good signal strength is -40dBm to -55dBm
- Your router has been changed/replaced,
- Wi-Fi password has been changed,
- No SSID available for 2.4GHz band,
- SSID for both 2.4G and 5G is same name
- Router has been relocated,
- dbell is connected to Wi-Fi extender but Wi-Fi extender is not connected to Router,
- MAC filter has been enabled but dbell MAC address is not added as safe device etc
- Static IP, Gateway and DNS is configured incorrectly
Wi-Fi signal strength:
The performance of a Wi-Fi wireless network connection depends greatly on radio signal strength. Distance between the wireless access point or Router and dbell, the signal strength in each direction determines the data rate available on that link, not the download/upload speed you have.
Wi-Fi signal strength and your upload/download speed are completely two different parameters. You can have highest upload/download speed but if your Wi-Fi signal strength is weak, meaning router or WAP cannot simply broadcast a good WiFi signal, it’s probably a good idea to consider employing Wi-Fi extender.
WiFi signal is usually measured in dBm. A signal between -40dBm to -55dBm is good for live video streaming from dbell, and -60dBm to -100dBm is poor.
How to check Wi-Fi signal strength:
Any mobile device that is internet capable can show you the strength of the Wi-Fi network in range. If you have an Android phone or tablet you may use Wi-Fi analyzer to check your Wi-Fi signal strength
Screenshot: Wifi Analyzer by farproc
We recommend a signal strength between -40dBm to -55dBm
3. In-sufficient Power: dbell will go offline when supplied power is insufficient. Noticeable Symptoms, dbell restarts after few minutes, makes a static or hum noise.
dbell requires wired doorbell transformer rated 16V 10VA.
To ensure dbell gets sufficient power join F & T together inside your pre-existing chime.

4. Corrupted microSD card: Corrupted SD card will cause dbell to go into offline state
Due to outdoor usage, SD card may get corrupted. Remove SD card and recycle power to resovle the condition.

5. New Router: Router has been changed but dbell is not synced with the new router
If you change the router, dbell will stop working until you sync dbell with the new router.
